What is PCU (Passenger Car Unit) in Traffic Engineering?

When analyzing roads, intersections, and traffic flow, engineers face a common challenge: vehicles are not all the same. A car, a motorcycle, a truck, and a rickshaw each take up different amounts of road space, move at different speeds, and influence congestion differently. To solve this, transportation engineers use the Passenger Car Unit (PCU) — […]

What is Rush Hour Traffic? How Engineers Calculate Peak Hour Traffic Volumes

When most people talk about rush hour traffic, they’re thinking about the frustrating congestion on roads during the morning and evening commute. Transportation engineers use a more technical term for the same idea: peak hour traffic. Understanding how traffic builds up during these busy times is crucial for designing roads, planning intersections, and evaluating new
