Traffic engineering is a branch of civil engineering that focuses on the design, management, and control of traffic flow and transportation systems to ensure safe and efficient movement of vehicles and pedestrians. Traffic engineering encompasses various characteristics and principles to achieve these goals.
In traffic engineering, the concepts of speed, flow, and density are fundamental for understanding and analyzing the behavior of traffic streams on roadways. These three parameters help describe how vehicles interact and move on the road.
Traffic volume measurement is a crucial aspect of traffic engineering and transportation planning. It involves collecting data on the number of vehicles passing a specific location on a road over a defined period. Traffic volume data is essential for various purposes, including traffic flow analysis, capacity assessment, congestion management, and infrastructure planning.
An Origin-Destination (OD) survey is a research method used in transportation planning and traffic engineering to collect data about the movements of people, vehicles, or goods between specific origins and destinations within a defined geographical area. The primary goal of an OD survey is to understand travel patterns, traffic flows, and transportation needs.
