Abstract

The target of this study is to build up a VISSIM simulation model and align it to find out volume-to-capacity proportions of turning movements at uncontrolled intersections under Indian mixed traffic conditions. Driver and traffic behavior related parameters are adjusted after examination of the field information. The microscopic simulation outputs of the calibrated VISSIM model are contrasted with the field capacity values assessed from gap acceptance. Classified Movement volumes gathered at a four-legged uncontrolled intersection in the state of Maharashtra is utilized. Driver Behavior parameters (car-following, lane changing and lateral driving) are initially decided for homogeneous movement having one of the six classifications of vehicles considered in the stream and after that the outcomes are accumulated to get the estimations of these parameters for a mixed stream. Every single other factors and movement activities on every methodology are kept as steady. The calibrated VISSIM model is then used to decide capacities (volumes) by flooding a section at once for non-priority movements. Simulated volumes were obtained for each movements and turns after the 7th run. Gap acceptance capacity is calculated using HCM 2010 formula for the intersection. Volume-to-capacity ratio is used as the critical measure for assessing traffic flow operations within the intersection. After assessment through calibration it was found that the uncontrolled intersection is operating under low to moderate congestion (volume-to-capacity ratio less than 0.85) thus experiencing lesser service delays.
