Walkability
The extent to which the built environment is friendly to the presence of people living, shopping, visiting, enjoying or spending time in an area.
3
Effective Factors on Walkability
Land use mix Street Connectivity Residential density (residential units per area
of residential use) Transparency which includes amount of glass
in windows and doors, as well as orientation and proximity of homes and buildings to watch over the street
Plenty of places to go to near the majority of homes
Placemaking, street designs that work for people, not just cars and retail floor area ratio

Benefits of Walking and Cycling
Transportation system benefits Environmental benefits Economic benefits Quality of life benefits Health benefits
5
Transportation System Benefits
Nearly half of all travel trips taken in the US are 3 miles or less in length; 28% are less than 1 mile. By converting short automobile trips to bicycling and walking, communities can get benefits from healthier air and reduced traffic congestion.
The American public saves from 5 to 22 cents for every automobile mile displaced by walking and bicycling through reduced pollution, oil import costs, and costs from congestion such as lost wages and time on the job.
6
Environmental Benefits
Approximately 160 million tons of pollution are emitted into the air each year in the US. air pollution contributes to the deaths of 70,000 people each year.
Short auto trips produce far more pollution per mile than longer trips.
Increased levels of bicycling and walking can reduce air pollution.
7
Economic Benefits
Increase mobility for people who cannot afford to own and operate a car by improvement of walking and cycling (a motor vehicle is one of the highest expenses after housing)
reduce health care costs by incorporating physical activity of pedestrian and bicycle transportation into people’s daily lives
8
Economic Benefits
Outdoor activities such as bicycling and walking are the most popular activities for people on vacation from work.
Trails and greenways can have a positive effect on the value of nearby properties. Recent studies indicate that there is a demand for more livable communities and, specifically, better bicycle and pedestrian facilities in the vicinity.
9
Quality of Life Benefits
Pedestrians add to the ambience and security of streets.
Providing a livable community is a necessary part of attracting and keeping businesses, and ensuring local communities remain competitive.
10
Health Benefits
There is a correlation between the built environment and the amount of routine physical activity, such as regular walking trips.
Pedestrian and bicycle transportation offers more opportunities for people to socialize than driving alone in automobiles.
Studies have shown benefits from routine exercise each day. Bicycling or walking to the store, school, or work also provides a time-efficient way of daily physical exercise.
11
Health Benefits
There are now nearly twice as many overweight children and almost three times as many overweight adolescents as there were in 1980.
Obesity and overweight are linked to the nation’s number one killer-heart disease-and other chronic conditions. One reason for Americans’ sedentary lifestyle is that walking and cycling have been replaced by automobile travel for all but the shortest distances.
12
Public Support for Cycling & Walking
Of 82 million American ridden a bicycle in a year:
46% stated they would sometimes commute to work by bicycle if safe bicycle lanes were available.
53% would do so if they had safe, separate designated paths on which to ride.
45% would do so if their workplace had showers, lockers, and secure bicycle storage.
47% would do so if their employer offered financial or other incentives.
13
Pedestrian Characteristics
1) Age Groups:
Children (0-12) Teenagers (13-18) Adults (18-40) Middle-Aged Adults (41-65) Senior Adults (65+)
14
Safe Environment for Children and Elderly
15
Older pedestrians have difficulty negotiating curbs
16
People with children often walk at slower speeds
17
Pedestrian Characteristics
2) Impaired Pedestrians:
Visually impaired Hearing impaired Mobility impaired Mentally/emotionally impaired Elderly with reduced abilities
18
Designing for All Pedestrians
When age or functional disabilities reduce a person’s mobility, sight, or hearing, a good design becomes very important.
19
Driveway slopes should not encroach into the sidewalk
20
Curb Cuts and Wheelchair Ramps
The ramps should be flared smooth into the street surface. Ramps should be checked periodically to make sure large gaps do not develop between the gutter and street surface. There is a need to remove accumulations of asphalt at the edge of the curb radius.
21
How to Encourage Walking and Cycling?
Better cycling and walking facilities Traffic calming of residential
neighborhood Restriction on motor vehicle use Traffic education Traffic regulation and enforcement
22
Better Cycling and Walking Facilities
Bike paths and lanes with exclusive rights of way, providing a connected , integrated, comprehensive bike route network
Wide, well-lit sidewalks with benches and plants
Clearly marked, well-lit crosswalks, often raised and with curb extensions and pedestrian-activated traffic signals
Car-free zones and special bicycling streets
23
Traffic Calming of Residential Neighborhood
Traffic calming is a way to minimize the negative impacts of traffic to improve safety (decrease fatality rate).
A wide range of measures are used to reduce the severity and number of accidents to improve safety for all road users, esp. pedestrians, and to influence driver behaviour. Traffic calming can be accomplished by installing road humps, speed cushions, raised junction plateaux, chicanes, road narrowing, and mini-roundabouts.
A variety of traffic calming techniques is intended to reduce vehicle speeds, and to discourage drivers from cutting through residential side roads.
24
Effects of Vehicle Speed on Safety
25
Traffic Calming Techniques
Physical measures that force cars to slow down:
Table/entry treatment Road narrowing and zigzag routing Speed humps and bumps Traffic circles
26
Table/Entry Treatment
More acceptable to emergency services and bus operators than standard humps
Slows down all approaching traffic to all arms
Can be used in isolation (they don’t have to form part of a series of road humps)
Reduces speed
27
Road Narrowing
Interrupt through traffic movement thereby reducing speed
Do not delay emergency service vehicles or affect bus operation
Cycle gaps can be incorporated
If cycle gap is not provided they can make safer crossing places for pedestrians
28
Round Top Hump
Reasonably inexpensive to install
Minimal disruption to traffic during construction & no loss of on-street parking
Effective at reducing vehicle speeds
29
Speed Cushions (Pillow Hump)
Accepted by emergency services and bus operators
Inexpensive to construct
No loss of on-street parking
Cyclists can pass between cushions
30
Traffic Education
Improved motorists training, with emphasize on how to avoid endangering pedestrians and cyclists
Compulsory traffic safety lessons for all school children by the age of 10, with testing by traffic police on actual traffic test courses, to ensure safe and defensive walking and cycling by an early age
31
Urban Design Issues
The residential units should be within easy walking or cycling distance of cultural facilities, shopping, and service establishments.
It is desirable to have paved sidewalks on both sides of all streets in urban and suburban areas to provide mobility for pedestrians.
32
Many developments focus on vehicle access without regard to pedestrian
access
33
Medians and crosswalks should be placed at
destination locations
34
Pedestrian-Friendly Environment
Getting people out of cars
Public transportation improvement Car-free zones in residential areas

Pedestrian Safety
Crosswalks can be used in combination with other treatments to improve safety.
Refuge islands, raised medians, raised crossings, curb extensions, and lighting are examples.

39
Intersection Issues for Pedestrians Safety
1) Improved pedestrian conspicuity Painted crosswalks in the roadway Extensions to move pedestrians out from
behind parked cars Improved horizontal and vertical sight
distances through the removal of extraneous curbside clutter
40
Intersection Issues for Pedestrians Safety
2) Speed reduction of motor vehicle drivers Raised intersections to alert drivers that the area is
not designed for rapid through movement and pedestrians can be expected
Right-turn slip lanes with exit angles between 50 and 60 degrees
3) Ease of movement from walkway to street level
Curb ramps to facilitate the transition from walkways to streets.
Raised intersections that eliminate the need for curb ramps and make the crosswalk a natural extension of the walkway
41

Conclusion
A comprehensive program for increasing bicyclists and pedestrians safety must combine the efforts of many people.
it is important to first determine current conditions before going through planning.
Implementing various strategies to reduce incentive for driving and disincentive for walking and cycling would be a good approach.
55
Reduce Disincentives for Bicycling & Walking and Incentives for Driving
Strategy 1: Add non-motorized options to agency motor pools
Strategy 2: Require companies and agencies to produce balanced transportation plans for their workforce’s commuting needs
Strategy 3: Include entry-level bicycling and walking activities in local recreational programming
56
Reduce Disincentives for Bicycling & Walking and Incentives for Driving
Strategy 4: Promote utilitarian non-motorized transportation through introductory fun events
Strategy 5: Offer key target audiences detailed information on utilitarian non-motorized travel
Strategy 6: Develop and disseminate a limited set of simple, but important, probicycling and prowalking messages
