Where can you find the segment accident rate calculation?

• A. Pg. 4-10 of Highway Safety Manual
• B. Pg. 22-6 of Highway Capacity Manual
• C. Exhibit 18-2 of Traffic Engineering Handbook
• D. Pg. 24-9 of Urban Planning Manual

Answer: (A)

The segment accident rate calculation is specifically detailed in the Highway Safety Manual. This manual provides guidance on how to analyze and mitigate accidents, using statistical methods to quantify safety performance on roadways. The content on pages like 4-10 lays out the framework for calculating accident rates per unit of exposure, typically vehicle miles traveled or some form of traffic volume measure.

Understanding accident rates is critical for transportation engineers and planners as it informs design decisions, safety measures, and resource allocation to improve roadway safety. By focusing on segment-specific data, professionals can more effectively target interventions where they are most needed. Other manuals, such as the Highway Capacity Manual or Traffic Engineering Handbook, serve different purposes, such as capacity analysis and general traffic engineering principles, but do not specifically address the segment accident rate calculation in the context found in the Highway Safety Manual.
