One of the most significant aspects of the traffic flow system is traffic volume. It is defined as the number of vehicles that pass through a given site in a certain amount of time, whether actual or expected. Transportation planners and engineers need traffic volume data because it is one of the first things they need to know when designing and developing a route. However, when discussing traffic volume, it is not always sufficient to just say "vehicles," because the sorts of vehicles in traffic can change over time. The Highway Capacity Manual (Highway Research Board) developed the unit of a passenger car equivalent in 1965 as a mechanism to assess traffic volume (PCE). PCE, or passenger car unit (PCU), is defined as "the number of passenger cars that will result in the same operational conditions as a single heavy vehicle of a specific type under specified highway, traffic, and control conditions" (Transportation Research Board 2010). The PCU factors can be used to convert diverse forms of traffic flow into homogeneous counterparts.
