Research On Urban Bicycle Network Planning

Although as a country of bicycle's manufacturing and using in large scale, ti's obvious for our country that the consideration on bicycle transportation in urban planning is not enough yet. Now the Bicycle transportation is still in inconvenient condition in most cities of our country.Bicycle is the main traffic mode in most of our cities, and the mixed traffic flow of vehicles and bicycles is the special phenomenon in our urban traffic. Therefor it is the key of improving urban traffic conditions to solve the problems coming with the mixed traffic flow. However, by far there is little research on the traffic design and control of bicycles in our country. This thesis is established based on this background.The research status of bicycles in the world is reviewed firstly to confirm the orientation and emphases of this thesis. Then, the condition of bicycle's development in our cities is summarized. Consequently, the deep discussion about the problems deriving from the urban bicycle traffic is made. At last, though detailedly analyzing the transportation characteristics of the urban bicycle, the bicycle flow model is established and from applying it the bicycle capacity model is getted. All above are the basis of the research on theory of urban bicycle network planning.In the aspect of the bicycle network planning, this thesis refered to the experience of the abroad, trying to change the traditional planning programming of the bicycle system planning. It gives a method to establish the reasonable bicycle transportation network with moderate developing principle, in order to achieve the real separation of motor vehicles and bicycles so that the traffic flow can be organized effectively. For more, a practice in the area within second ring of Xi'an is made in order to offer a new idear for establishing a bicycle network.The bicycle transportation network should have not only bike-paths at different levels, also the nodes in the network, that is the parking lot and the transference, which is a complete bicycle network system. The nodes mentioned above are studied at the end of this thesis.
