thpercentile queues are rounded to nearest 25 feet.

bDue to roadway narrowing, left-turn lane storage may be limited. At a minimum, 175 feet should be provided (this isthe distance prior to where the road narrows).

cN/A = Not Applicable because this is the through movement.

dThe 5-lane cross-section on Willamette Street starts approximately 175 feet south of 29

thAvenue. The through-right

lane should extend this full length.

TRAFFIC LEVELS OF SERVICE

Analysis of traffic volumes is useful in understanding the general nature of traffic in an area, but by itselfindicates neither the ability of the street network to carry additional traffic nor the quality of service

afforded by the street facilities. For this, the concept oflevel of service has been developed to subjectively

describe traffic performance. Level of service can be measured at intersections and along key roadway

segments.

Level of service categories are similar to report card ratings for traffic performance. Intersections are

typically the controlling bottlenecks of traffic flow and the ability of a roadway system to carry traffic

efficiently is generally diminished in their vicinities. Levels of Service A, B and C indicate conditions

where traffic moves without significant delays over periods of peak travel demand. Level of service D and

E are progressively worse peak hour operating conditions and F conditions represent where demand

exceeds the capacity of an intersection. Most urban communities set level of service D as the minimum

acceptable level of service for peak hour operation and plan for level of service C or better for all other

times of the day. TheHighway Capacity Manualprovides level of service calculation methodology for

both intersectionsandarterials.1 The followingtwo sectionsprovideinterpretationsoftheanalysis

approaches.


18/28

UNSIGNALIZED INTERSECTIONS (Two-Way Stop Controlled)

Unsignalized intersection level of service is reported for the major street and minor street (generally, leftturn movements). The method assesses available and critical gaps in the traffic stream which make it

possible for side street traffic to enter the main street flow. The 2000 Highway Capacity Manualdescribes

the detailed methodology. It is not unusual for an intersection to experience level of service E or F

conditions for the minor street left turn movement. It should be understood that, often, a poor level of

service is experienced by only a few vehicles and the intersection as a whole operates acceptably.

Unsignalized intersection levels of service are described in the following table.

Level of Service Expected Delay (Sec/Veh)

A Little or no delay 0-10.0

B Short traffic delay >10.1-15.0

C Average traffic delays >15.1-25.0

D Long traffic delays >25.1-35.0

E Very long traffic delays >35.1-50.0

F Extreme delays potentially affecting > 50

other traffic movements in the intersection

19/28

SIGNALIZED INTERSECTIONS

For signalized intersections, level of service is evaluated based upon average vehicle delay experienced byvehicles entering an intersection. Control delay (or signal delay) includes initial deceleration delay, queue

move-up time, stopped delay, and final acceleration delay. In previous versions of this chapter of the HCM

(1994 and earlier), delay included only stopped delay. As delay increases, the level of service decreases.

Calculations for signalized and unsignalized intersections are different due to the variation in traffic

control. The 2000 Highway Capacity Manualprovides the basis for these calculations.

Level of DelayService (secs.) Description

A 80.0 Forced Flow/Excessive Delays: Represents jammed conditions. Queues may block upstreamintersections. This level occurs when arrival flow rates exceed intersection capacity, and is considered to

be unacceptable to most drivers. Poor progression, long cycle lengths, and v/c ratios approaching 1.0 may

contribute to these high delay levels.
