1、 74 Main Points of Choice of the Urban Road Line 1. The overview As one of the products of social development and one of the main component elements of modern cities, the urban road has respect to the coordination and sustainable development of cities and shows the cities potential of economical and

2、 cultural development. The original network of urban road needs to be programed and adjusted again , especially owning to the rapid expansion of cities and the great increase of the number of cars in recent years. The urban road is not a seperated object any more, and its development is increasingly

3、 restricted by other factors of city develpoement. Therefore, the line-bit choice should show the coordination and integration between roads and the environment. The reasonable line-bits will have a positive impact on the economy,society, environment and peoples life. On the contrary, the unreasonab

4、le line-bits will influence the surroundings of them and bring some side effects. 2. The comparison and selection of line-bits With the increasing importance attached on such issues as sustainable develpoement, environment protection and land usage, the thinking modes of road design should be change

5、d, from only emphasizing the cost of initial construction stage to considering the cost of both construction and operation, only the safety and interest of the users to the feelings of other residents and the public, only the visible terrain and objects on the ground to the construction conditions s

6、uch as geology, historical relics and mineral resources, only the coordinative design among the roads themselves to the coordinative reseach between roads and their such surroundings as natrue, ecology, society and humanity. The comparison and selection of line-bits means that the designer, in his d

7、ay-to-day job, compares the different lines in different aspects and chooses the most economical, practical,and reasonable one which also meets the countrys relevent standards and policies. However, the selection is made with the designers overall consideration of the economy, cultrue, environment,

8、pedestrian, safety and road-intersection, and under the premise of not having influence on the publics life and economic develpement. 75 3. The main points. At present, the line selection in the design of urban road is not only a purely technical proof process of the line-bit comparison and selectio

9、n, but also a process of implementing the pre-planning.At the same time,it needs the respect for natural environment,the adoption of public opinion,the prudence of demolition works and the consideration of economic interests of the parties, especially the protection for water resources and cultural

10、relics. Only the above points having been finished, the selected road line could receive broad supports,reflect the planning intention, promote local economic development, and improve the function of urban road network. 3.1. The implementation of the pre-planning The choice of urban road lines shoul

11、d be based on the reasonable plan of urban land usage and urban road network.And it is necessary to consider both the urban land usage and urban road network. In recent years, with the rapid development of urban construction,the phenomenon that urban planning can not keep up with urban construction

12、frequently appears, which also has led to many reconstruction and waste of resources. How to find a better mode of operation to minimize the losses, is the first issue worthwhile exploring in the urban construction planning. Only having the full knowlegde of pre-planning intention and understanding

13、of the funtion of project planning, can people imlpement the planning better. 3.2. Respect for natural environment According to the report on Chinas ecological problems ,ecological damage caused by the construction of road transportation and developing of mineral resources has become one of the main

14、 reasons for the deterioration of ecological environment, and intends to be more and more serious. General designers are accustomed to dig roads in mountains and build bridge over waters. This has resulted in that it will take a long time for the completion of infrastructure projects,the large tract

15、s of vegetation and Original topography to recover or not resume, or even resulted in a series of environmental disasters . The awareness which the designers need to establish is that road is a part of the whole environment of its location,so when we select and design the road lines,we should attach

16、 importance to the protection of and 76 respect for the environment so as to make the environment better ,but rather damage the surroundings. Therefore, as a responsibile designer,one needs to tirelessly and repeatedly optimize the line programs. Line selection embodies respect for the natural envir

17、onment at the following points: 1.Take up less arable land； keep away the basic protected farmland； 2.Evaluate on the basis of environment；keep away the sore piont of environment； 3.Conform to the topography and geomorphology； reduce the high filling and deep digging. 3.4. Prudence of demolition wor

18、ks According to the previous experience on engineering, the problem of removal and compensation is often an important factor influencing the project advancement. Therefore, we should pay attention to the road line-bit as much as possible to avoid dense building areas and to reduce the cost of demoli

19、tion and resettlementthe. When we have to demolish some buildings,we should try our best to carry on the countrys resettlement subsidy policy, and we need to not only safeguard the lawful rights and interests of the demolition parties, but also guarantee the smooth progress of construction projects.

20、 The Property Law of Peoples Republic of China was put in practice on October 1, 2007.Later on, the demolition for urban road construction or land development should be considered more carefully. 3.5 The consideration of economic interests of the parties In the process of selecting road lines scheme

21、, on the premise of standard meeting, if the alignment of road is bad, its investment is small； if the alignment is good, the investment is large； if the investment is small, its enforceability is poor；if the investment is large, its operability is high. All these make it difficult to set down which

22、 one is better. “The Guide for New Concept of Highway Design” which is compiled by the Ministry of Transportation has proposed to establish a design concept of “the cost of full life-cycle”,thats to say, the road lines should be intercompared in such stages as construction, maintenance, operation and management,and both the construction cost and operating cost should be taken into account. In addition,we need to carry out the economic analysis in the feasibility study for the roads
