Evaluation of Level of Service and Traffic Capacity for congested River Bridges of Surat City

Abstract

India is developing country in the world. There are many complex problems related to transportation system
is observed in the country. These include ever increasing population, vehicular growth and traffic congestion. Gujarat is
the one of the top five fastest developing state of our country. Surat city is developing city. The city is 2nd biggest city in
Gujarat and 9th biggest city in India. In Surat city- the fourth fastest developing city of the world-at many places the
bottleneck conditions on the roads occurs due to limited availability of road space. Due to bottleneck condition at the
bridges across Tapi river, traffic congestion is occurring. Out of the 10 bridges across the Tapi River in Surat city. some
of the bridges which is connecting the commercial and residency area in the city are witnessing heavy amount of traffic
during pick hours which leads to traffic jam and bottlenecks condition at some places. After reckoning survey the three
bridges namely Sardar Bridge, Amroli Bridge and Savjibhai korat Bridge Are selected for Traffic flow capacity and level
of Service analysis. Therefore, it is necessary to quantify the Traffic characteristics in existing traffic conditions on
selected bridges and understand the responsible factors for suggesting improvement in existing Traffic congestion over
selected bridges. In this study, it is proposed to find traffic flow capacity and Level of Service by measuring traffic speed,
flow and density parameters on the selected bridges during peak hours. This may be helpful to check whether existing
bridges are capable to handle existing as well as future increased traffic flow safety or not.
