惠州市鹅岭立交改造工程方案研究

为充分论证环形立交改造方案的科学性和合理性,通过间隙接受理论模型和国内普遍推荐的信号交叉口通行能力计算方法分析了惠州市鹅岭立交现状和改造后的通行能力。结果表明,环形立交的通行能力较低,已不适应当今汽车保有量较高的城市发展需求,改立交为信号控制的平交口可有效提高交叉口的服务水平。可见,改环形立交为平交是合理、可行的。

Study on Reconstruction Engineering Scheme of Huizhou Erling Interchange

In order to fully demonstrate the scientificity and rationality of the reconstruction scheme of ring interchange, the present situation and the traffic capacity after reconstruction of Huizhou Erling Interchange are analyzed through the gap acceptance theory model and the capacity calculation method of signalized intersection generally recommended domestically. The results show that the traffic capacity of ring interchange is relatively low, which is not suitable for the urban development demand with higher car ownership. The reconstruction of the interchange into the signalized intersection at grade can effectively improve the service level of interchange. It can be seen that it is reasonable and feasible to reconstruct the ring interchange into signalized intersection.
