Performance Evaluation of Urban Roadway Links Using V-Box

Present study attempts to evaluate the operational efficiency of urban roadway links using V-Box. An urban arterial of 5.8 km length in Surat city of Gujarat is selected and divided into six links based on the number of intersections in the entire facility. All links are identical in geometry (six-lane divided) with different land use patterns. In order to evaluate the operational efficiency of these links, the number of runs of different categories of vehicles including motorized two-wheelers (2W), auto-rickshaw (3W), big car and small car (4W) and heavy vehicle (bus) has been taken at different time periods. A number of 30 runs of each vehicle category were taken on the entire facility for peak hours and non-peak hours. The collected data has been analysed for spatial and temporal variation in speed for different vehicle categories. The spatial variation has been checked by analysing the inter-segmental variation of speed. Also, within each segment, the variation of speed for different category of vehicles for peak and non-peak hours has been studied. Further, cumulative speed plots have been plotted to check the variability of speed for different segments for different vehicle categories. Furthermore, the excess speed over posted speed limit for different mid-block sections has also been checked.
