In which manual can the intersection accident rate, R, be found?

• A. Traffic Engineering Handbook
• B. Highway Safety Manual
• C. Highway Capacity Manual
• D. Pedestrian Facilities Handbook

Answer: (B)

The Highway Safety Manual (HSM) is specifically designed to provide data and methodologies for evaluating roadway safety, including the calculation of accident rates at intersections. It offers comprehensive guidelines on how to assess crashes and understand factors affecting safety, making it the go-to resource for intersection accident rates.

The other manuals serve different purposes, which is essential to note. The Traffic Engineering Handbook provides general principles and practices related to traffic engineering, but it does not focus specifically on safety and crash data. The Highway Capacity Manual primarily addresses the analysis of traffic flow and capacity but does not include methodologies for calculating accident rates. Lastly, the Pedestrian Facilities Handbook concentrates on the design and implementation of pedestrian infrastructure, therefore it does not contain information on intersection accident rates.

Thus, the Highway Safety Manual stands out as the authoritative guide for this specific information regarding intersection accident rates.
