Area Occupancy Characteristics in Traffic Flow on Urban Highway: A Case Study


Syed Omar Ballari
Abstract

Density is one critical parameter in understanding the traffic flow characteristics, besides speed and flow. It gives thought regarding how jam-packed an area of street is furthermore it is pointer of Level of Service being given to street clients. Traffic thickness has been considered as significant parameter for characterizing Level of Service on multi-path interstates furthermore to contemplate traffic attributes. Nonetheless, in heterogeneous rush hour gridlock conditions, thickness doesn't generally mirror the grouping of traffic as vehicles of various measurements utilize the expressway. Also, path order is poor in India and commonly two little vehicles, for example, auto-rickshaw and bike may involve similar path. Likewise the vehicles may go without sufficient horizontal clearances one next to other without carefully following the paths. Numerous period path markings are not kept up appropriately and subsequently vehicles stream with no order. In such circumstance assurance of path insightful limit probably won't be suitable and keeping in mind that examining traffic trademark, thickness probably won't be the genuine pointer of inhabitance. The idea of Area inhabitance of vehicle could be progressively suitable parameter as it considers level anticipated region vehicle with no confinement on snare length and width of road. The case study was carried out on a three lane divided urban road. Traffic counts, speed, occupancy were collected using video graphic technique. The data was then extracted to determine classified traffic volume, average speed of different vehicles and the average speed of the traffic streams and also the area-occupancy considering all the three lanes together in one direction were determined. Different combinations of traffic volume were then generated using VISSIM and the relationships between various flow parameters independently with the area-occupancy were developed, calibrated and validated.
