The diagram which shows all important physical conditions of an accident location like roadway limits, bridges, trees and all details of roadway conditions is known as

A) pie chart B) spot maps C) condition diagram D) collision diagram

Discuss

Answer & Solution

Answer: Option C

Solution:

The correct answer is (C) condition diagram.
Let's break down why:
* A condition diagram is specifically designed to illustrate the physical characteristics of a location, including roadway features, bridges, trees, and other relevant details. Think of it like a detailed site map focused on the environment.
* A collision diagram focuses on graphically representing accidents to visualize and analyze traffic incidents.
* A pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportion and not related to physical conditions.
* Spot maps are used to show the geographic distribution of something, often incidents, by marking locations on a map, not all important physical conditions.
