Research On Key Problem Of Bicycle Lane Planning In Old Districts:Xuchang Example

The original city centers evolved into old districtss along with the rapid development of many cities in our country. Old districts as a high population density area (mostly refers to resident and employment population) collected kinds of residential, commercial, cultural and other facilities, but its road width and traffic space is limited which induced the increasingly contradictions between all kinds of mixed traffic and the limited road space resources.The traffic problems of old districts reflect the main traffic problems of the whole city.Whereas the non-motor vehicle trips in old districtss often account for over 30% of the total amount of travel, So old districts traffic problem mainly represents for competing for road space between the non-motor vehicles and cars, however the present road traffic space allocation more inclined to the car, so the transport facilities is mainly for car which could make the motor vehicle traffic in a passive position on the road space.In this paper we took Xu Chang old districts as an example, first studied the key problems in design of old districts bicycle lanes, then focused on the traffic characteristics of old districts, the basic characteristic of the old districts traffic flow and the key issues need considered in the bicycle lanes planning, combined with practical engineering and then put forward the old districts bicycle lanes design theory which could be applied in practice. The specific content of the papers was shown as follows:First of all, the problems of the old districts road such as traffic parking facilities, infrastructure, bicycle traffic safety as well as the accessibility were summarized based on the analysis of XiAn, XuZhou and KaiFeng city traffic status, and then analyzed the root causes of the problem, in order to emphasize the importance of planning design of bicycle lanes.Secondly, the related literatures at home and abroad were analyzed from three aspects including the bicycle traffic flow theory, the bicycle traffic demand and bike paths planning and design, then summarizes the research results, which has been done provided a theoretical basis and support for the full text of the research.Thirdly, the thesis studied the bicycle traffic travel characteristics from macro and micro aspects and then analyzed the factors that influence the bicycles and analysis on the old districts bicycle traffic problems, then analyzed the type of bike lanes, the old bicycle road planning principle, planning and road network planning method, intersection and some the key problems in traffic environment design.Finally, the present situation and problems of the old districts traffic were investigated and analysed and existing problems in the bicycle traffic were pointed out, the bicycle road design experience at home and abroad combined with the actual situation of the old districts road bike path in order to present practical development goals and strategies, and summarized the problems of bicycle lanes design which needed pay attention to, so as to put forward the corresponding solution strategy.
