NCHRP 599 - Default Values for Highway Capacity and Level of Service Analyses

Based on the assembly of an extensive set of field data from across the United States, this report presents valuable information on the appropriate selection of default values when analyzing highway capacity and level of service. The report will be useful to planners, geometric designers, and traffic engineers who do not have ready access to field data for an analysis. The report also describes how to prepare service volume tables, which can be a useful sketch planning technique.

NCHRP 616 - Multimodal Level of Service Analysis for Urban Streets

NCHRP Report 616: Multimodal Level of Service Analysis for Urban Streets will be of interest to public agencies responsible for the planning, design, and operation of urban streets. This report provides a method for assessing how well an urban street serves the needs of all of its users: auto drivers, transit passengers, bicycle riders, and pedestrians.

NCHRP Report 500 Volume 12: A Guide for Reducing Collisions at Signalized Intersections

The goal of the AASHTO Strategic Highway Safety Plan is to reduce annual highway fatalities by 5,000 to 7,000. This goal can be achieved through the widespread application of low-cost, proven countermeasures that reduce the number of crashes on the nation’s highways. This twelfth volume of NCHRP Report 500: Guidance for Implementation of the AASHTO Strategic Highway Safety Plan provides strategies that can be employed to reduce the number of collisions at signalized intersections. The report will be of particular interest to safety practitioners with responsibility for implementing programs to reduce injuries and fatalities on the highway system.

NCHRP Web-Only Document 128: Multimodal Level of Service Analysis for Urban Streets: Users Guide

An urban street is unique among the various facility types operated by public agencies, because its right-of-way is shared by multiple modes of travel, each using their assigned portion of the right-of way. To adequately evaluate the quality of service provided by the facility, one must consider the implications of facility design and operation on the auto driver, the bus passenger, the bicyclist and the pedestrian.
