Title: Study of Methods of Collecting Traffic Volume at Roundabouts
Abstract: Urban transport is one of the systems that city's social and economic development can 't be separable from,supporting the development of urban transportation. Transport infrastructure is a kind of public welfare,and its construction should be built on the basis of adequate research and analysis.Obtaining basic data of traffic is essential for making targeted traffic demand management measures,improving the traffic environment,ensuring good traffic conditions. Roundabout traffic volume is not easy to collect,especially in multi-lane and large-scale roundabouts,at which traffic flowing of each direction is often complicated. Introducing an double-constrained gravity model,this paper considers the amount of exiting traffic,and proposes a new way to observe the flow of traffic around based on a small amount of survey data,providing an easy way to get around the island traffic. The results show that the new method is reasonably practicable for the roundabout traffic survey.
