厦门BRT 1号线的交通安全设计

Design of Traffic Safety for Line 1 of BRT in Xiamen

研究目的:厦门BRT1号线是国内第一条高架的并预留升级为轨道交通条件的BRT,由于桥上没有设置紧急停车带也没有设置BRT的上下匝道,可能发生的突发事故将会对交通造成堵塞,也可能引发二次交通事故。为了杜绝险情,消除安全隐患,针对高架桥上可能存在的安全风险进行分析,提出有针对性的安全措施。研究结论:通过研究与分析,对高架桥上的故障车辆应在13 min之内安全转移,恢复交通正常运营;同时针对BRT车辆的特性,对车辆和防撞护栏进行了特殊设计,并配合BRT相关的交通安全设施设计等措施,确保行车安全。

Research purposes： The Line 1 of BRT in Xiamen is the first elevated BRT that remains the condition for upgrading it into the urban rail transit.As there is no emergence zone and up and down ramps on the bridge,the traffic jam and the secondary traffic accident probably happen if the event happens suddenly.In order to avoid and eliminate the latent danger,the analysis of the safety risk on the bridge is made and the relative safety measures are presented.Research conclusions：Through the analysis and study,it is thought the failed vehicle should be moved away within 13 minutes to restore the normal traffic.At the same time,the vehicle and guard rail should be specially designed along with the relative designs of the facilities for the traffic safety according to the characteristics of the BRT vehicle to safeguard the traffic safety.
