Road networks are design for elimination traffic congestion, decrease in vehicle delays, increase in the level of
service, increasing in traffic queue at intersections and increasing in the road safety are subjected to smooth traffic
flow. In the city like Bangalore increase in the vehicle numbers leads to congestion in the road network in certain
places, resulting in the decrease in the Level of service and increase in the vehicle operation cost. These problems
should get solved by providing better infrastructure planning in a particular intersection to improve Level of
service. PTV VISSIM traffic modeling helps in simulating real city traffic, which can manage traffic, design of
intersections and suggesting alternative routes. In order to improve the Level of service PTV Vissim software is
used.
