Then, the authors make it clear the strategies to be adopted for solving the existing traffic problems in the ancient urban area of Suzhou(AUAS), namely insisting on the goal based strategy; the strategy to develop the public transit system in priority and decreasing the demand on cars from the view point of land use strategy. On the basis of such analysis the authors put forth proposals about major measures to be taken to improve traffic conditions of the AUAS, such as construction of express artery ring around the ancient city, appropriate transformation of the roads in the AUAS and rational distribution of car parking areas at the outskirt, which are of positive significance in guiding the protection of the AUAS and transportation construction. In this paper, specialized software is used to establish criteria for the construction scale and extent analysis and evaluation of the ancient city construction project, which is of some reference significance to the transformation of old urban areas in other cities.展开更多

It traces out the isochrones according to the discrepancy of the time distance between the different sites from the outside of the city and the down town, It can be clear and intuitional to show the different temporal relationships between the outside of the city and the city centre with the temporal map, The problem of traffic congestion, with its potential /br urban chaos, has increased dramatically with a growing number of vehicles and the continuing aerial expansion of Guangzhou. Both transit riders and drivers find it is a great difficulty to try to acquire the necessary information from urban spatial movements. Valuable time is lost due to the absence of good transportation information. So, the paper analyzes a case in Guangzhou communication with Geographic Information System （GIS）, and uses the most popular vehicles, including buses and taxis that are used to measure the temporal distance in the city. and then proposes the design of a new map that better reflects the status of urban communication, and attempts to change the relationship between one point and another potnt of travel, reducing the amount of time allocated to such. often complex, movements, This paper also points out the obstacles associated with Guangzhou＇s existing traffic congestion, and puts forward a strategy aimed at better d .efining the need of linking the temporal map to spatial map of Guangzhou.展开更多
