A Review Paper on Driving Behavior Modelling

The Micro- Scopic traffic simulation model. PTV VISSIM has been widely in use for management analysis as well as transportation operations. Step wise simulation, less expensive, safer simulation and quicker in analyzing makes it superior when compared with other Micro- Scopic simulation software. These models completely rely on their accuracy and reliability for decision making and traffic controlling decisions. Although VISSIM possess default values for every input parameters, it is necessary to change the values that replicate the present traffic conditions. The major traffic conflicts were identified at intersections for both signalized junction as well as un-signalized junctions. Drivers tend to enter the paths though the capacity of those paths were lesser than its volume. One of the major reason behind these conflicts were identified as the driving behavior. Therefore the VISSIM provides the luxury to enhance the driving behavior parameters such as Car- following, Lane changing priorities, number of preceding vehicles, Lateral behavior, signal decisions and standstill headway parameters were calibrated accurately to replicate the present conditions. The Micro- Scopic simulation results suggest that the default values produce higher speed, large queue length and short travel time than observed in the field. The measure of effectiveness were generated. Thus, calibration process requires a careful examination on how the simulated vehicles behave and its importance in balancing the values of parameters that enhance the network performance.
