Modelling view to reduce urban traffic congestion

Urban traffic congestion is an important concern of authorities which affects the journey time of the Road users in the metropolitan cities. It is important to understand and Model the criteria of congestion and influencing factors for transportation planning especially to reduce delays and congestion pricing. This paper aims to develop an equation using simplistic method on the influencing factors of traffic congestion, such as Density of intersections, width of carriage way, Pedestrian crossings, U-Turns, available foot path space, Parking areas, Homogeneity in road network, and segregation of heterogeneous traffic. The factors chosen to develop the model are based on real time video graphic survey in the selected urban traffic corridor with a view to develop a model among the measurable factors and the factors like driver behavior, local traffic rules, pedestrian crossings and functioning of traffic control systems etc,in the background. The real data collected from different trips made on the selected roadway in the study route including Cyber towers of Hi-tech city in Hyderabad is used to practically evaluate delays and note the factors of congestion. The results show that, the density of intersections, the density of U-turns, number of pedestrian crossings, non- homogenous road network and density of Bus-stops have positive effect on travel time and delays in Hyderabad city roads. It is also observed that there is cumulative negative effect of fixed factors like Geometrics, Land Use and Road Infrastructure, and traffic parameters like headways, delays and capacity of road on travel time. In Summary, this function has a simple structure and high flexibility so that it can be used as a tool for other cities, having heterogeneous traffic.
