摘要:
为保障高速公路的高效运行,提出适用于客货分离式高速公路主线与匝道协同控制算法.选取被广泛应用的ALINEA模型作为匝道控制的基本模型,再依据高速公路主线上下游交通流的变化进行入口匝道调节,确保入口匝道下游主线的占有率接近期望占有率,使高速公路主线在接近最大交通容量时充分考虑主线上游交通量对匝道调节率的影响,从而实现主线与匝道协同控制.利用Vissim软件进行仿真,结果表明,在运行效率方面,采用协同控制策略的客货分离形式高速公路优于传统ALINEA控制策略的客货分离式高速公路,远优于客货混行、无控制策略的高速公路.
Abstract:
To enhance the efficiency of freeway under suparating truck from passenger vehicles condition,a coordinated control of freeway mainline and ramp based on modified ALINEA model was proposed.Firstly,the ALINEA model was chosen as the basic model of ramp control,the entrance of ramp was regulated on the basis of the change of the upstream and downstream traffic flowin the main line of the highway,ensuring that the occupancy rate of the downstream main line was close to expected toccupancy.Meanwhile,when the main line of the highway was close to the maximum capacity,the impact of the upstream main line traffic flow on the ramp regulating rate must be noticed.Using the Vissim software simulation,the study showed that,in terms of operating efficiency,the separation of truck and carwith cooperative control strategy outperformed the separation of truck and car using the classical alinea control strategy,far superior to truck and car mixed control scheme.
