杭州湾大桥进出口加减速车道运行速度模型

Operating Speed Model for Acceleration and Deceleration Lane of Hangzhou Bay Bridge Passageway

摘要:

通过驾驶模拟实验,对在灾害性天气下的杭州湾大桥进出口加减速车道的运行速度进行了试验研究,建立了加减速车道的自回归与时间序列运行速度模型,该模型主要用于高速公路安全运行速度控制标准的制定,研究成果已在杭州湾跨海大桥上得以应用.

Abstract:

Based on vehicle driving simulator experiments,the autoregressive model predicting the operation speed on the acceleration and deceleration lane was developed under atrocious weather condition.The model can be used to make the safe operation speed of the expressway for traffic control.The study results are applied to the Hangzhou Bay Bridge.

Key words:acceleration and deceleration lane; vehicle driving simulator experiment; time series; autoregressive model; operation speed
