Abstract:
Aiming at the hospitalizing trip features of the aged, the trip impedance of public transportation is introduced.An evaluation model which can accurately detect the accessibility of high order urban hospitals for the aged is established with the help of GIS technology.Furthmore, the established model is employed to detect the accessibility of the first-level hospitals in Xi′an city.The results showed that the traffic connection between the hospitals and their service objects is an important factor to the feasibility and effectiveness of accessibility evaluation. It is suggested that special evaluations on the accessibility of hospitals for the aged are needed so as to achieve the goal of human-oriented in urban traffic planning.The well-served spatial pattern of hospitalizing accessibility for the aged in Xi′an city has established in recent years because of the public transit metropolis strategies.The accessibility constraints can be divided into 3 types: the imprison, the antagonism and the running-in, corresponding countermeasures to settle the low accessibility of hospitals will be done by the planning administrations.
KeyWords:
