Origin and destination studies are carried out for:
- APlanning of road network for vehicular trafficCorrect
- BAccident studies
- CPavement design
- DGeometric design
Solution
Concept
Purpose of origin and destination studies
Formula
NONE
Step-by-step solution
1. Origin and Destination (O-D) studies measure travel patterns by identifying where trips begin and end. 2. This data reveals travel desires and traffic volume distributions between different zones. 3. Consequently, O-D data is essential for planning comprehensive road networks, new routes, and mass transit systems. Answer: A
Explanation
Origin and destination studies collect data on where trip movements begin and terminate across a region. Transportation engineers use this travel demand information to plan new highway routes and optimize vehicular traffic networks. Therefore, these studies are primarily conducted for road network planning.
Why the other options are wrong
B) Accident studies analyze crash frequency and location using collision diagrams. C) Pavement design is based on structural loading, soil strength, and traffic volume. D) Geometric design depends on speed, terrain, and traffic volume.
Shortcut
Origin-Destination (O-D) studies = Planning and routing the road network.
Common mistake
Assuming origin and destination studies are used directly for structural pavement design rather than overall network planning.
Correct answer: A) Planning of road network for vehicular traffic
