基于浮动车数据调查方法的交叉口延误计算

An Approach of Signalized Intersection Delay Calculation Based on Floating Vehicles Data Survey Method

针对目前城市中现有的GPS浮动车研究城市交叉口延误估计方法,为了摆脱传统计算方法,提出一套利用浮动车数据估计延误的新方法。在分析了车辆经过交叉口的受阻过程,界定了交叉口范围以及车辆经过交叉口的畅行速度的基础上,确定了交叉口延误的计算流程以及计算公式,并且对此方法进行了验证。

Aiming at the current research on the signalized intersection delay calculation of GPS floating vehicles in city, a new method to estimate delay using the floating vehicle data is proposed to get rid of the traditional method. The delay process at signalized intersection is mainly analyzed, and the range and expedite travel speed of the signalized intersection is determined, which lays a foundation for determining the calculation process and calculation formula of the signalized intersection delay. At last, this method is validated based on the real data.
