摘要
针对城市快速路因交通需求大于交通供给而出现的交通拥堵现象,考虑入口匝道处车辆对城市快速路优先使用权的需求,通过分析优先放行的效益,提出了优先放行的入口匝道控制策略,即在交通高峰期让等级较高的车辆优先进入城市快速路.文中还研究了优先放行的城市快速环形路段算法,并给出了具体的算例.结果表明:将该策略运用到入口匝道控制上,能限制等级较低的车辆进入,提高道路的使用效率.
In order to overcome the traffic congestion due to the traffic demand for urban expressways that exceeds the traffic supply, the benefit of priority entrance is analyzed by fully considering the requirements of vehicles for priority entrance on the on-ramp of urban expressways, and an on-ramp control strategy based on the priority en- trance is proposed, which permits vehicles with top priority to drive into urban expressways in a peak traffic condi- tion. Moreover, an algorithm of priority entrance for the annular road sections of urban expressways is presented, and the corresponding numerical example is conducted. The results indicate that the proposed strategy is applicable to on-ramp control and helps to raise the use efficiency of roads because it can prevent vehicles with lower priority from entering urban expressways.
