Assessment of network traffic congestion through Traffic Congestability Value (TCV): a new index

Summary/Abstract: Traffic congestion is a major and growing problem in urban areas acrossthe globe. It reduces the effective spatial interaction between different locations.To mitigate traffic congestion, not only the actual status of different routes needsto be known but also it is imperative to determine network congestion in differentspatial zones associated with distinct land use classes. In the present paper,a new formula is proposed to quantify traffic congestion in the different spatialzones of a study area characterized by distinct land use classes. The proposed formulais termed the Traffic Congestability Value (TCV). The formula considersthree major influencing factors: congestion index value, pedestrian movement androad surface conditions; since these parameters are significantly related to landuse in a region. The different traffic congestion parameters, i.e. travel time, averagespeed and the proportion of time stopped, were collected in real time. Lowervalues of TCV correspond to a higher degree of congestion in the respective spatialzones and vice-versa and the results were validated in the field. TCV differsfrom the previous approaches to quantifying traffic congestion since it focuses onthe causes of network congestion while in previous works the focus was generallyon link flow congestion
