Analysis of Various Web Data for Visualization of Travel Time and Accessibility

This paper proposes a method for the calculation of travel time and the visualization of accessibility based on multiple data sources. In an environment where transport data are not fully open, construction of novel transportation systems which are planned based on enough data is limited. Our method calculates travel time based on data of multiple sources, which are not fully corrected data and visualizes novel accessibility by defining a novel index based on the travel time. The index is calculated from variance and mean of the travel time. As a result, a visual comparison of the accessibility between each area is realized by utilizing the proposed method. Thus, integrating some transport data is expected to contribute to constructing the optimal transportation system. Experimental results show the effectiveness of our evaluation method.
