چکیده مقاله
Safe Signal timing in urban intersections as bottlenecks of road facilities can be achieved through evaluation of traffic conflicts Traffic conflicts are among safety indices whichhave the ability to proactively predict safety conditions of a site without any crash occurrence Attempt is made here to develop models in order to design a safe signal timingfor an isolated intersection in Isfahan, Iran, using surrogate safety measures To this end, vehicle trajectories of several simulated scenarios with two, three and four phase signals are assessed in SSAM software VISSIM simulation software enables simulators to export trajectory files of vehicles to the SSAM environment in order to determine different types of conflicts After defining several transportation parameters in SPSS environment, linear regression models are obtained for different types of vehicle conflicts and average delay The results can be utilized to calculate and compare different timing and phase planning schemes in order to decrease delay and different types of conflicts The main contribution of current research is consideration of different signal phases in proposed models which can contribute to the design and planning of safe signal timing at three lane signalized intersections
