Traffic Management and Accident Investigation

Definition of Terms:

Traffic is a movement of vehicles along a route where passengers and cargoes are carried by

transportation.

Traffic Management it comprises all public surfaces , facilities and agencies having responsibility for

licensing, approving, maintaining and controlling the flow of traffic and the use of traffic facilities.

Accident (Legal meaning) an accident is any happening beyond the control of a person the

consequences of which are not foreseeable. ( There is no criminal liability in accident provided, the

following requisites or elements under the law must be satisfied; 1.) performance of a lawful act; 2.)

with due care; 3.) causes injury to another by mere accident; 4.) without any fault or intention of causing

it.)

Fortuitous Event an event which takes place by accident and could not have been foreseen. In other

words it is an Act of God which could neither be foreseen nor resisted, such as earthquake, lightning,

flood, and the like.

Force Majure is an inevitable accident or casualty, an accident produced by any physical cause which is

irresistible. In other words it is an Act of Man, such robbery, fire, fault, negligence, rebellion, etc.

Defensive Driving is an act of driving while preventing accidents despite of the wrong actions of others

aggravated by the existence of adverse driving conditions. Which requires knowledge, alertness,

foresight, judgment and skill.

Last Clear Chance - it means that the driver who is in the better position to prevent the accident

shoulders the responsibility of preventing the accident. The last clear chance principle is always applied

in any traffic accidental investigation in order to justify penalized the driver who was not defensive in its

driving.

State of Necessity there is state of necessity even if the injury to a person results in his death, because

self-preservation always makes the actor feel that his own safety is greater than that of another.

Elements or requisites under the law; 1.) the evil sought to avoided actually exists ; 2.) the injury feared

be greater that that done to avoid it; 3.) that there is no other practical and less harmful means of

preventing it.

Imprudence indicates deficiency of action. If a person fails to take the necessary precaution to avoid

injury to a person or damage to property, there is imprudence. Imprudence usually involves lack of skill.

Negligence indicates a deficiency of perception. If a person fails to pay proper attention to use due

diligence in foreseeing the injury or damage impending to be caused there in negligence. Negligence

usually involves lack of skill.

Motor Vehicle shall mean any vehicle propelled by any power other than muscular power using the

public highways, but exempting road rollers, trolley cars, street sweepers, bulldozers, graders, fork-lifts,

cranes, vehicles which runs only on rails or tracks, tractors, trailers, and traction engine.

Articulated Vehicle- shall mean any motor vehicles with a trailer having no front axle and so attached

that part of the trailer rest upon the motor vehicle and a substantial part of the weight of the trailer and

of its load is born by the motor vehicle.

Transfer Evidence it is an evidence found at the accident scene that will connect to the suspected

vehicle and with the crime scene.

Traffic Actuated Signal is controlled by an individual using his hands in signaling the flow of traffic

wherein traffic shall proceed in accordance with the desire of the individual controlling the flow of

traffic.

Development of Roads

Stone paved streets are found in the city of Ur in the Middle East dating back to 4000 BC. The Romans

built roads to last. one meter in height, the road was built up in four layers: slabs embedded in mortar

formed the foundation; masonry made up the second; the third, finally, the rolling surface could be

simply broken stones, paving stones, or bricks depending on traffic.

1750 Trsaguet in France and Metcalfe in the UK proposed a method of construction relying on a firm

well-drained foundation of large rocks topped by progressively smaller ones, forming a convex surface

to make it more impervious to water.

Around the end of the eighteenth century Telford in the UK proposed a similarly robust concept,

perhaps too much so for traffic needs (he had been looking forward eagerly to steam-powered vehicles),

with the result that it was rather expensive due mainly to its thickness and very solid foundation,

intended to compensate for unstable roadbeds.

Macadam at the beginning of the 19th century to develop the far more economical approach which is

still used today in adapted forms, usually with a coating of bitumen to seal it.

Development of Motor vehicle

One of the most important landmarks in engine design comes from Nicolaus Otto who in 1876 invented

an effective gas motor engine. Nicolaus Otto built the first practical four-stroke internal combustion

engine called the "Otto Cycle Engine," and when he completed his engine, he built it into a motorcycle.

Gottlieb Daimler is thought to have invented the first real motorcycle in 1885.

The original Benz Patent Motorwagen, first built in 1885 and awarded the patent for the concept

In 1879, Benz was granted a patent for his first engine, which had been designed in 1878. Many of his

other inventions made the use of the internal combustion engine feasible for powering a vehicle.

Key Personalities in Transportation

Ferdinand Verbiest, a member of a Jesuit mission in China, built the first steam-powered vehicle around

1672 which was of small scale and designed as a toy for the Chinese Emperor, that was unable to carry a

driver or a passenger, but quite possibly, was the first working steam-powered vehicle ('auto-mobile')

In Russia, in the 1780s, Ivan Kulibin developed a human-pedalled, three-wheeled carriage with modern

features such as a flywheel, brake, gear box, and bearings; however, it was not developed further

Franois Isaac de Rivaz, a Swiss inventor, designed the first internal combustion engine, in 1806, which

was fueled by a mixture of hydrogen and oxygen

In November 1881, French inventor Gustave Trouve demonstrated a working three-wheeled automobile

that was powered by electricity

hydrogen powered FCHV (Fuel Cell Hybrid Vehicle) was developed by Toyota in 2005

A compressed air car is an alternative fuel car that uses a motor powered by compressed air. The car can

be powered solely by air, or by air combined (as in a hybrid electric vehicle) with gasoline/diesel/ethanol

or electric plant. This type of vehicles will be released this year 2009.

Development of Traffic Signs

On 10 December 1868, the first traffic lights were installed outside the British Houses of Parliament in

London, by the railway engineer J. P. Knight.They resembled railway signals of the time, with semaphore

arms and red and green gas lamps for night use. The gas lantern was turned with a lever at its base so

that the appropriate light faced traffic. Unfortunately, it exploded on 2 January 1869, injuring the

policeman who was operating it

The modern electric traffic light is an American invention. As early as 1912 in Salt Lake City, Utah,

policeman Lester Wire invented the first red-green electric traffic lights.

On 5 August 1914, the American Traffic Signal Company installed a traffic signal system on the corner of

East 105th Street and Euclid Avenue in Cleveland, Ohio.It had two colours, red and green, and a buzzer,

based on the design of James Hoge, to provide a warning for colour changes.

Pedestrian Crossing

The pedestrian crossing were instituted in Britain in 1934. The roads were marked by dotted lines. On

the pavement there were striped Belisha beacon light poles named after Britain's Minister of Transport

L. Hore-Belisha. The Zebra crossing with black and white stripes was developed after the second world

war.

First Box Junction

Box junctions, marked with yellow cross-hatching, were introduced in London during 1964. The aim was

to prevent traffic blocking junctions when it could not proceed and this was successful.

First Traffic Police Woman

Police women were used for traffic control duties for the first time in Paris in 1964. In Delhi we

introduced women traffic police in 1989.

The Motor Car Act

The Motor Car Act of Britain came into force on 1st January 1904. It required that all cars be registered

and carry a number plate, and all motorists to have a driving licence. But there was no driving test to

pass and the licence was obtained by filing up a form and paying the fee at a post office. The act made

dangerous driving an indictable offence.

Origin of our Traffic Laws

CONVENTION ON ROAD TRAFFIC

Geneva, 19 September 1949

Components of Traffic Management

Traffic Education comprises all means for public information and the safety education of both drivers

and pedestrians as to traffic laws and the use of traffic facilities and an adequate training programs in

traffic control throughout the police unit.

Traffic Engineering that phase of engineering which deals with the planning and geometric design of

streets, highways and abutting lands, and with traffic operation thereon, as their use is related to the

safe, convenient and economic transportation of persons and goods.

Traffic Law Enforcement comprises al police activities in connection with the direction of traffic,

regulation and education of drivers, determine potential offenders, constant patrol, giving of assistance

in the prosecution of offenders, investigation of accidents, follow-up complaints, requesting police

action, warning, summoning or arrest of violators, reporting of road hazards and obstruction.

through which vehicular traffic is guided, that will segregate pedestrian.

Kinds of Traffic Islands

1. Divisional and or Pedestrian Barrier

2. Channelizing Island

3. Refuge Island

4. Rotary Island

Traffic Signs a device mounted on a fixed or portable means of words or symbols, officially created and

installed for the purpose of regulating, warning and guiding traffic.

Types of Traffic Signs

1. Regulatory Signs - are intended to inform road-users of special obligations, instructions or

prohibitions which must comply. A round shape is used for regulatory signs with exception of stop and

yield signs.

2. Warning Signs - are intended to warn road-users of danger on the road and to inform them of its

nature. These signs have an equilateral triangular shape with one side horizontal.

3. Guide or Informative Signs - are intended to guide road-users while they are traveling or to provide

them with other useful information.

Types of guide signs

1. Route markings is usually found on highways composed of several lanes which are going into

different direction.

2. Destination and distance signs is usually erected on highway informing the motorist as to the

number of kilometers and at which way to take going to its place of destination.

3. Information signs is usually erected on highway which informs the motorist of the establishments in

the era, such hospitals, restaurants, restrooms, hotels, and other establishments which provide services

to motorist.

TRAFFIC SIGNAL LIGHTS

Traffic Light Signals is a power operated traffic control device by which traffic is warned or directed to

take some specific actions.

Traffic Actuated Signal is controlled by an individual using his hands in signaling the flow of traffic

wherein traffic shall proceed in accordance with the desire of the individual controlling the flow of

traffic.

LIGHT: FLASHING RED

1. This is the same as STOP SIGN.

2. STOP at the designated line.

3. Vehicles will be crossing from the other side

4. Expect pedestrians to cross at the pedestrian lane.

5. PROCEED WHEN CLEAR.

LIGHT: FLASHING YELLOW

1. This is the same as a YIELD SIGN.

2. Proceed through the intersection with caution.

3. You have the right of way over a flashing RED light.

4. Vehicles on the other side will proceed to a FULL STOP.

LIGHT: STEADY GREEN AND STEADY LEFT/RIGHT ARROW

1. Vehicles can go straight or vehicles on the left lane can make a left turn.

2. Vehicles can go straight or vehicles on the right lane can make a right turn.

3. The RIGHT GREEN signal might or might NOT have a road sign disallowing a right turn while the RED

lights is ON.

Most traffic jams are caused when traffic lights are inoperative either due to brownouts or when they

are out of order.

Whenever you approach a traffic signal light with all its lights OFF, and there are no traffic enforcers

directing traffic, IT IS SAFER TO SLOW DOWN OR COME TO A COMPLETE STOP and make certain what

the flow of traffic is.

Too many accidents have happened with drivers on both side is SUPPOSED TO BE GREEN.

PAVEMENT MARKINGS

Pavement Markings are markings on the roads and surfaces whereby a message is conveyed by means

of words or symbols, officially reflected for the purpose of regulating, warning and guiding traffic.

TYPES OF PAVEMENT MARKINGS

1. Curve markings are used to show where parking is legally prohibited or not allowed, such Bus Stop,

or in front of a fire hydrant, drive way.

2. Object Markings are painted on fixed poles, and on vertical ends of bridges and ports to avoid

accidents.

3. Reflectorized Markings are used to mark hazardous areas and also used as delineators or road

limits, these delineators are aids especially during night driving, particularly when the alignment of a

road changes and might confused the operator of the vehicle.

4. Striped Curb Markings are markings used in traffic islands in order to warn the driver of the traffic

island on the road and aids the motorist to its traffic lane.

5. Painted Crosswalk are placed at intersections and other places where there is considerable

pedestrians traffic to provide pedestrians with safety zones when crossing.

6. Broken White Lines is used to define or separate traffic lanes. It permits crossing from one lane to

another if there is ample passing distance, and if the opposing lane is clear of traffic.

7. Solid White Line is used to separate opposing streams of traffic. Crossing is unlawful except where

ample distance exists and where the opposing traffic lane is clear of traffic.

8. Solid Yellow Line is your driving lane prohibits you from passing other vehicles.

9. Double Yellow Line indicates two way traffic; were crossing of pedestrian and motorist is not

allowed. It separates the opposing flow of traffic.

10. Broken Yellow Lines is a two way/highway which means no overtaking or passing is permitted only

when the road ahead is clear.

11. Stop Line it indicates where stop should be made.

Traffic Enforcement Action

Enforcement action is usual limited to:

1.) verbal or written warning;

2.) summon or citation requiring the offender to appear in court;

3.) arresting traffic violators for traffic violations not attended

4.) suspension or revocation of license;

5.) payment of fines or civil damages, and;

6.) prosecution of criminal offenses in relation to traffic.

Functions of Traffic Engineering

1.) Fact finding surveys and recommendation of traffic rules and regulations.

2.) Supervision and maintenance to the application of traffic control devices.

3.) Planning of traffic regulations.

Objectives of traffic Engineering

1,) To achieve efficient, safe, free and rapid flow of traffic.

2.) To prevent traffic accidents and casualties.

3.) To present the role of traffic engineering in reducing the needs for police action and simplifying

police performance.

4.) To show that good police action and performance makes engineering plans effective.

Elements of street and highway traffic

1.) The road user

2.) The vehicle and its load

3.) The road.

Police officers main functions in Traffic

1.) Police traffic directions

2.) Police traffic law enforcement

3.) Police traffic accident investigation.

Elements of traffic accident are;

1.) the vehicle involved

2.) the highway

3.) the road user.

TRAFFIC ACCIDENT INVESTIGATION

The primary function of police in traffic is the protection of life and property, and accident investigation

is very essential in trying to recover the cost of damage in an accident.

Its purpose are:

1.) securing facts upon which to base an accident prevention program;

2.) determining responsibility or accident when possible. Ascertaining the facts of accident so that those

involved can properly exercise claims under our civil law.

The technique of investigating accident is to go back in reconstructing the accident as far as possible

from the position of final rest of the traffic unit involved and determine the multiple causes and

circumstances of the accident.

TRAFFIC ENFORCEMENT ACTION

1. Detection

2. Apprehension

3. Prosecution

4. Adjudication

5. Penalization

TRAFFIC PATROL

Traffic Patrol May be conducted on area or line bases which refer to the territory covered. It includes,

for enforcement purposes, stationary observation to detect drivers behavior as well as moving about to

detect violators. Traffic patrol reefers to the observation of road conditions, the behavior of the drivers

and other users of vehicles for the purpose of traffic supervision and law enforcement and providing

authorized traffic-connected services to the public.

Line Patrol Conducts observation either in moving or stationary observation at a certain route or point

of a major street in a city.

Area Patrol Conduct observation either by moving patrol or stationary observation in a certain area,

which included a number of streets roads or sections of a highway.

Stationary Observation Observation of traffic conditions of a selected place, usually one with

unfavorable accident experiences for traffic law supervision. Stationary observation may be

conspicuous, visible or concealed, depending upon the location of the patrol unit in relation to the

street under observation.

Conspicuous Observation Stationary observation in which the observer remains in full review of traffic

conditions.

Visible Observation Stationary observation in which observer is full view but so located, for example,

at Side Street, so as to require effort on the part of traffic users to discover the observer.

Concealed Observation Stationary observation in which the observer is not visible to persons using

ordinary power of observation form the roadway being observed.

Purpose of Traffic Patrol

1. Deterrent to violations and dangerous driving.

2. Detecting and apprehending violators.

3. Observing and reporting traffic conditions.

4. Observing and reporting road conditions, including view obstruction, which needs attention.

5. Providing certain services to the public.

Handling emergencies as they arise and keeping traffic flow smoothly.

Road Intelligence Unusual points of serious congestion must be noted. You may observe an unusual

amount of delay at a certain intersection each morning and when you learn that it is due to loading or

unloading of passengers on a No Loading Zone, be sure to report the situation at once to your superior

officer.

Report congestion that ties up traffic for a block or more. Also report unnecessary delay at stop signs or

signals which are installed when traffic is heavier. Include in your report all road and bridge conditions.

TRAFFIC ACCIDENT ANALYSIS

1) condition of the motor vehicles involved in the accident;

(2) condition of the drivers at the time of the accident;

(3) load of the vehicle;

(4) weather condition;

(5) characteristics of the road, which involves the design condition, and inhabitants of the place of

accident; (6) presence or absence of traffic sign and its condition. All these factors must considered in

order to fully uncover the reasons of the accident, and thereby provide a factual bases in coming-up

with a traffic prevention program and traffic plans and programs.

TRAFFIC INVESTIGATION

(1) securing facts upon which to base an accident prevention program;

(2) determining whether or not laws have been violated, gathering evidence which will reveal the road

user responsible for the accident, and taking on-the-scene police action; and

(3) ascertaining the facts so that those involved in accidents can properly exercise claims under our Civil

Law.

The determining factors of the time and place in Key Events

Key Event means the one which characterizes the manner of the occurrence of the traffic accident. It

determines the time, place, and type of accident.

Point of Possible Perception is the place and time at which the unusual or unexpected movement or

condition could have been perceive by a normal person.

Delay in Perception or Perception Time it is the time between the point of possible perception and

actual perception.

Prompt Perception is the perception of hazard which is actually nearly the possible accident.

Maximum Delayed Perception occurred when the traffic unit does not sense a hazard until he hits

another vehicle.

Point of No Escape is the place and time after or beyond which the accident cannot be prevented by

the traffic unit under consideration.

Point of Impact is used to mean as the point of initial contact, sometimes it is considered the point of

maximum engagement or center of force.

Final Position is the place and time when the object involved in the accident finally come to rest

without application of power.

Chain of Events is the making up of accident or the link which explains the occurrence of the accident

and its components are present in every accident.

Perception of hazard is the point of sensory warning at which the operator sensed the approaching

hazard. The driver may not comprehend or recognized the hazard in all of its implications at this point of

perception, but there was a warning. The normal routine is perception, realization, or recognition,

decision, and action.

Possible perception - is a link in the accident chain dealing with the reaction of a normal person. Prompt

perception occurs when possible and actual perception are very close. Maximum delayed perception

occurs when actual perception is delayed until impact shock alerts the driver..

Encroachment is the movement of a vehicle into the path assigned to the other traffic unit.

Evasive Action is the first action taken by a traffic unit to escape from a collision course or otherwise

avoid the hazard.

Point of no escape is that location and that time after or beyond which an accident cannot be

prevented by the driver or pedestrian.

Initial Contact it is the first accidental touching of an object collided with by a traffic unit in motion.

Maximum Engagement is the greatest collapse or overlap in a collision.

Disengagement is the separation of a traffic unit in motion from an object with which it has collided.

Final Rest of Stopping it usually stabilizes the accident situation where both vehicles in a collision has

ceases its force, and stopping may occur with or without control by the driver or pedestrian

Skidmarks are marks on the road left by tires that are not fee to rotate usually because brakes are

applied strongly to lock wheels.

Nine (9) Kinds of skidmarks

1. Pavement Grinding is the collection of many fine scratches and some larger one form by particles of

gritty materials such as stone, gravel, glass and sometimes bit of metal embedding itself in the rubber of

the tire or in the thread pattern and being ground or scored against the road surface.

2. Tire Grinding is the collection of particles of rubber ground from the tire surface by gritty paving,

especially before the tire gets hot enough smear. It occur on hard, dry, granular surfaces, particularly

weathered or new but not traffic-polished cement.

3. Erasing is a clean light area where a sliding tire had erased or removed dirt from the pavement.

Erasing is most likely to be found on traffic-polished concrete road.

4. Squeeze Mark are areas where a sliding tie rubs moisture of the surface in its path. It occurs on

some kind of surface as erasing except that the surface is wet.

5. Smear of Soft Material materials such as snow, mud, or debris usually wet smooth or spread by a

sliding tire. It occurs on road covered with snow, or mud.

6. Smear of Bituminous Material is excess asphalt or tar, usually warm which spread by a sliding tire

this occurs in pavement patches and joints in very warm weather and else where when there is an

excess of tar or asphalt bleeding to the surface.

7. Tire Smear is a rubber melted from the tire rather than material melted from the road by a sliding

tire.

8. Scrub of Tire during Collision collision of cars usually cause the wheel to jam and prevents it from

turning. If the vehicles are moving there will be a heavy scrubbing action between tire and road surface.

9. Furrow is a ploughed depression made by a sliding tire with material piled-up on each sides and

usually at the end. If the soil is smooth and sticky, there may be soft material smear in the bottom of the

rut.

Types of Ending Skidmarks

1. Overlapping Skidmark occurs when the rear wheels track on top of the front wheel marks in sliding.

2. Front Wheel Marks are in long skids on hard pavement with bituminous binders. Front wheels

skidmarks in which most of the mark is at edge of the tire.

3. Rear Tire Marks are relatively faint because of lesser weight on the tire in slowing. They may show

thread grooves when the front tire marks do not.

4. Flat Tire Scuffs will leave marks by a scrubbing action even without application of brakes due to

overload.

5. Gaps in Skidmarks are interruptions in skidmarks made by release of brake pressure and its

reapplication.

6. Skip Skid are skidmarks that are broken or interrupted without brakes being release.

7. Curb in Skidmarks are usually gentle slides toward the edge of the road which is simply downhill.

Scuff Marks are signs left on the road by tires that are sliding or scrubbing while the wheel is still

turning.

Types of Scuff Marks

1. Decelerating Scuff are left while the vehicle is slowing by braking effort and tires are both sliding

and rolling.

2. Accelerating Scuff are left by a wheel driven by the engine and spinning on the ground.

3. Side Scuff are scuff marks left by a tire that is free to rotate without braking or power the sliding

sidewise, these are usually left by a vehicle steering around a curb and also in collision.

4. Combination Scuff are combination of slide with either decelerating or accelerating scuffs.

5. Flat Tire Scuff are marks lefts on the road by the edges of under-inflated or greatly overloaded tires.

They are usually smear of rubber, a flat tire rolls it become a very hot specially at the edges where the

pressure is greatest.

6. Scrub of Tire during collision it is much the same when the wheel is rotating as when it is locked.

7. Furrows by a rotating and sliding wheel are little different than one with a locked wheel.

CAUSES OF TRAFFIC ACCIDENT

1. Direct Causes the direct causes of an accident are observable by witness and participants, or may be

constructed from physical evidence found at the scene. Since a direct cause relates to the action of the

human part of the traffic unit concerned it is a behavior cause. Usually only four direct causes are

considered in accident investigation;

a. Initial Behavior - Any movement, position, or failure to signal intent to make a traffic maneuver that

creates a dangerous situation and is either hazardous, illegal, improper, or unusual may be initial

behavior of a nature justly term a direct cause of an accident.

b. Speed Too fast for conditions is the direct cause of many accidents.

c. Delayed Perception Is inattention to the major task of operating a motor vehicle, and occurs when

the driver is distracted by conversation with other occupants of the car, lighting a cigarette or cigar,

looking at a roadway or the scenery, or glancing at occupants of nearby vehicles.

d. Faulty Evasive Action Faulty evasive action always occurs after perception and is the reaction of a

driver or pedestrian to a hazardous situation on the highway.

2. Mediate and Early Causes These mediate and early causes of an accident are also termed condition

causes in formalized accident investigation procedure.

A mediate cause of an accident occurs between the early and the direct causes in the time span leading

to the accident, but it has a closer relationship to the direct cause than to the early causes.

A mediate cause should not be listed unless it explains the direct cause of an accident. A mediate cause

of an accident is an irregular or unusual condition of a vehicle, the road, the weather, or of a road user

(driver or pedestrian) that explains on of the four direct causes of an accident: initial behavior, speed,

delayed perception and faulty evasive action.

3. Early Causes - An early cause of an accident results from the act of any individual, or the failure to act

by any person, which creates conditions leading to the chain of events making up an accident.

An early cause of an accident has been defined as an act or negligence on the part of an individual or an

organization which causes or permits a mediate cause to exist.

HIT AND RUNINVESTIGATION

Characteristics of Hit-and Run Drivers

The hit-and-run accident is entirely and premeditated, of course, and the driver usually feels remorse at

having done harm to someone.

1. After living the scene, he dreads or frighten of being caught.

2. He may have left the accident scene because he was shocked, injured, or intoxicated.

3. He may have been too confused to know he was doing.

4. He may have a long record of violations or accidents and therefore a terrible fear of getting further

involve with the law.

5. More often, he fears financial loss specially if he does not have liability insurance.

6. Hit-and run drivers do not have a establish method of operation unlike with criminals.
