Abstract
The paper presents space occupancy (SOC) as a measure of state of traffic congestion in real time. To accurately measure state of traffic, space occupancy (SOC) is calculated as the percentage length of highway occupied by vehicles, taking into account length of every vehicle. The paper presents the concepts of SOC and describes the usefulness of utilizing SOC compared to density. The relationship between SOC and density is also determined and a traffic simulation model CELLSIM is used to evaluate the accuracy of each parameter. The parameters were studied using different length of vehicles and mix of traffic. SOC more accurately determines the magnitude of congestion and may be used to set accurate thresholds of traffic congestion. The concepts described can be applied to incident detection in real time control of network traffic flow in intelligent Transportation Systems.
