| 摘 要： | 通过合理布置港内道路,优化道路长度解决港区集装箱车流拥堵问题,保证港口车流的运行通畅,是提高港口运营效率及服务水平的有效途径。以港区内集装箱车流的速度-密度-流量关系为基础,并对密度函数进行了线性化、堵塞突变、堵塞推移的假设,利用几何原理解决时空积分的困难,推导出港区集装箱车道的最优长度表达式。通过实例计算,验证该表达式的可靠性,从而为原有港口道路优化改造及新建港口道路设计提供了充分的计算依据。

| Abstract: | The effective solution for the improvement of the port operating efficiency and quality to solve the container port jam problem is to arrange the road line and optimize the road length.Based on the relation between the velocity-density-flow rate,three hypothesis are employed to solve the difficulty of time and space integration by using the geometric principle,and the optimum length expression is finally deduced.Through the comparison between the calculating result and the practical data,the reliability of ... |
