Study On Planning And Design Of The Facility Humanization Of Mountain City Traffic

With the rapid expansion of the development of social economy and city, city road network is experiencing a rapid development process. Although state and local governments have put forward appropriate norms and standards in the planning and design of city road network, but these standards are only in the meet traffic demand and the level of safety, to further consider the nature of the road traffic facilities, and for the existence of the mountain city traffic facilities humane the problem is more prominent. Therefore, this paper studies the design of indicators, in the mountainous city road network traffic running characteristics of road network and road key nodes, puts forward a set of the mountainous city road traffic facilities from the macro to the micro humanized programming humanization design of mountain city traffic facilities humanization design proposal.First, analysis of the mountain city traffic facilities planning and design method and design principle of the analysis, in the planning and evaluation of mountainous city road network, the main analysis of the evaluation method of the evaluation method and the network already has the capacity of road network in mountainous city road; the key node analysis, the main analysis of the city road nodes involved in the crossing, intersection, Lane reduction zone, the instructions and other aspects of the research status, research methods and design principles.Secondly, from the analysis of mountainous city road network is not humane reasons, puts forward the overall train of thought of mountainous city road network planning of the humanity. Study on mountainous city road network capacity based on the road network facilities on the one hand, the foothold for the density of road network and the capacity of road network. On the other hand the research of city road network planning of mountainous human traffic running state based on the road network, humanized service level, traffic network equilibrium coefficient of noun. And select the examples to verify the scientificity and rationality of the research results.Finally, select the road interchange, road intersection, Lane from the mountainous city road key nodes in a reduced area and road guide signs on four aspects. Research of Road Interchange, mainly referring to the existing road intersection, and then improve the combination of topography and traffic characteristics of the mountain city; lane reduction zone is presented when the reduction is greater than a successive reduction when the lane, and Simulation of parallel Duan Changdu; the road guide sign designand setting recommendations mainly presented in the specification on the basis of the existing classification of traffic signs.
