Abstracts: In this Project we examine A study of mixed traffic behaviour and its management control is most important work to be carried out now days. As we know there are so many traffic related problems at various megacities which are increasing day by day. So we have decided to study such problems and finding out the specific solutions for these types of traffic related problems. So we have selected Shahibaug (Under Bridge) nearer to the Airport at Ahmedabad for our study.
Fuzzy logic has been widely used to develop an adaptive traffic signal controller because it allows the qualitative modeling of complex systems. However, existing research has developed the Fuzzy Logic Traffic Signal Controller (FLTSC) based on unmixed traffic conditions. These FLTSC are not suitable for mixed traffic conditions in developing countries, where traffic flows consist of different types of vehicles with a wide variation in their static, dynamic and operational characteristics. This paper describes the design and evaluation of an adaptive traffic signal controller based on fuzzy logic for an isolated four-way intersection with specific reference to mixed traffic in developing countries. The driver is designed to respond to traffic demands in real time. Video image processing has been proposed to capture traffic data such as the maximum queue length (in meters) and the average occupancy rate (in%) of each intersection approach. The proposed FLTSC uses maximum queue lengths and average occupancy rates collected during the previous cycle in order to estimate the number of seconds of green time required by each set of signal groups (stage) during the next cycle. The effectiveness of the proposed FLTSC was examined and analyzed by the VISSIM simulation program. The performance of this controller should be contrasted with the Fixed Time Controller (FTC) and Vehicle-Driven Controller - Extension Principle (VAC-EP) for different traffic conditions at a simulated four-way intersection. The results of the simulation indicate that the performance of the proposed FLTSC is generally better than the FTC and the VAC-EP, especially in cases of traffic that varies over time.
