“…Introduced by [1], he state that accessibility is "potential opportunity to interact" or generalized of "connection between population through distance". It has been widely discussed by [17], [18], [19], [20], and [21]. The equation below shows the form of accessibility.…”

Abstract. Sustainable transport is closely related to quality of life in the community at present and in the future. Some indicators of transport sustainability are accessibility measurement of origin/destination, the operating costs of transport (vehicle operating cost or VOC) and external transportation costs (emission cost). The indicators could be combined into accessibility measurement model. In other case, almost traffic congestion occurred on the condition of mixed traffic. This paper aimed to analyse the indicator of transport sustainability through simulation under condition of various traffic composition. Various composition of truck to total traffic flow are 0%, 10% and 20%. Speed and V/C are calculated from traffic flow to estimate the VOC and emission cost. 5 VOC components and 3 types of emission cost (CO2, CH4 and N2O) are counted to be a travel cost. Accessibility measurement was calculated using travel cost and gravity model approaches. Result of the research shows that the total traffic flow has indirect impact on accessibility measurement if using travel cost approach. Meanwhile, the composition of traffic flow has an affect on accessibility measurement if using gravity model approach.

“…Geert man and van Eck claims that this option is attractive as many existing modelling programmes can be used without much change [4]. By use of GIS integrated graphics and attribute data management capabilities, edit and update road network information, combined with the characteristics of urban road traffic road network of Hohhot weighted network dataset is added as a GIS layer.…”

Abstract. In order to explore changes in accessibility and connectivity of urban traffic network before and after the construction of subway, traffic networks within the Second Ring road, Hohhot, was analyzed based on complex network theory. Firstly, the urban road traffic network and the urban compound traffic network with the adjunction of the subway to former were mapped. Secondly, the node degree, clustering coefficient, average path length and node strength of the two networks were calculated based on SuperMap. Finally, the eigenvalues obtained above were compared and analyzed. Results show that both of the two traffic networks have some characteristics of small clustering coefficient reflected in random network and scale-free network. The latter, compared to the former, network diameter and average shortest path reduce, the average node degree and average node intensity increase. That is to say, with the adjunction of the subway, the connectivity and the accessibility of the entire network are significantly improved, and its carrying capacity increases remarkably.

“…AMs such as Hansen (1959), Wilson (1971), Erlander (1977), Erlander and Stewart (1978), and Geertman and Van Eck (1995) follow this format. These AMs generally are spatial interaction, potential-type formulas that assume a positive relationship between the number of opportunities available and a location's accessibility while accounting for attractions and the deterring effect of distance.…”
