Which book includes the segment accident rate, R?

Which book includes the segment accident rate, R?

• A. Highway Capacity Manual
• B. Traffic Engineering Handbook
• C. Highway Safety Manual
• D. Urban Planning Manual

Answer: (C)

The Highway Safety Manual (HSM) is specifically designed to provide methodologies and tools for estimating the safety performance of roadways and transportation facilities. Within this context, the segment accident rate, R, is a critical metric used to assess safety performance by measuring the frequency of accidents over a given segment of road. The HSM includes comprehensive statistical models and guidelines that utilize this rate to facilitate the evaluation of safety interventions and to inform decision-making in roadway design and traffic engineering. The other referenced manuals, while useful in their own rights, do not focus primarily on accident rates in the same comprehensive manner. For instance, the Highway Capacity Manual focuses on the capacity of roads and traffic flow, emphasizing how to evaluate and forecast traffic operations rather than specifically addressing safety metrics. The Traffic Engineering Handbook provides a broad array of traffic engineering principles and practices but does not emphasize the analysis of accident rates as a standalone metric. The Urban Planning Manual typically deals with broader land use and transportation planning issues, rather than focusing explicitly on roadway safety and accident rate analysis.
