Optimization Model of Regional Traffic Signs for Inducement at Road Works

A variety of pipelines are distributed under urban roads. The upgrading is bound to occupy certain road resources, compress the driving space motor vehicles for a long time, aggravate traffic congestion in construction section, and then affect operation whole region. reasonable layout signs inducement guide flow area where section located conducive promoting balanced distribution regional network, so as achieve reduction automobile exhaust emissions sustainable development traffic. In this paper, optimization method proposed. Taking maximum amount guidance information that can provide objective function, taking volume, characteristics intersection nodes standard deviation saturation independent variables, model facilities constructed, which optimize affected by goal minimum number information. results case study show among 64 alternative locations be set area, eight optimal finally determined setting points through model, effective increment largest at time. proposed paper used reference promote located.
