摘　　要：随着机动车保有量的增长,导致交通拥堵日益突出,BRT(Bus Rapid Transit)公共交通系统是解决城市交通问题的一种有效手段,与道路交通有着相辅相成的关系,而道路交通对BRT系统的运营速度、到站的稳定性具有直接影响。首先通过分析BRT走廊对道路交通的有利与不利影响因素,总结出带来的有利因素影响大于不利因素影响,并提出通过BRT专用道的拓宽改造、以及选择合理站位等市政设计手段来降低不利影响程度;其次经过对Medan BRT项目的实证研究,从交通安全、通行效率等两方面,进一步佐证BRT专用道改造思路,结合交叉口布设站台方式,能有效减少BRT走廊的增设对交通安全和交通效率的不利影响,最后根据意向问卷调查,对Medan BRT进行交通影响预评估分析,印证了BRT系统引导私人交通向公共交通转移,可以有效缓解城市交通压力。With the growth of motor vehicle ownership,the traffic congestion has become increasingly prominent.The bus rapid transit(BRT)system is an effective means to solve the urban traffic problems,and has a complementary relationship with road traffic.However,the road traffic directly affect the operating speed and arrival stability of BRT system.Firstly,by analyzing the favorable and unfavorable factors of BRT corridor on road traffic,it is concluded that the influence of favorable factors is greater than that of unfavorable factors.And it is proposed to use the municipal design means of widening and reconstructing BRT lanes,and selecting reasonable platform locations to reduce the degree of adverse impacts.Secondly,through empirical research on the Medan BRT project,the reconstruction ideas of BRT dedicated lane are further evidenced.Combined with the platform layout at intersections,the adverse effects of the addition of BRT corridors on traffic safety and traffic efficiency can be effectively reduced.Finally,based on the intention questionnaire survey,the traffic impact pre-assessment analysis on Medan BRT is conducted to confirm that the BRT system guides the transfer of private traffic to public transportation,which can effectively alleviate the urban traffic pressure.
