IMPACT ANALYSIS OF SPEED RESTRICTION MEASURES USING VISSIM 5.40

Abstract

In this work, the impact of speed restriction measures on road safety and level of service were studied and the real time situation is modeled using micro simulation software VISSIM 5.40. The result shows that the simulated situation resembles the real time situation since the R2 value ranges between 0.7-0.9 and due to the presence of humps the travel time gets increased and the Level of Service (LOS) gets reduced. Due to the installation of speed breakers there is no significant reduction in the number of accidents in the study stretch. This study also describes a study conducted to establish practical geometric design guidelines of speed control humps for the use of road engineers. A statistical relationship between geometric characteristics of speed control humps and speeds of the automobiles is developed and models have been suggested for the use of practicing engineers. This relationship can be used as a tool for designing hump geometry for a particular hump-crossing speed.
