| 概要 |
This study introduces a novel approach to analysis impact of road configuration on road traffic crash. The proposed method is developed based on network analysis and use four centrality parameters tha...t are connectivity, choice, local integration and global integration to analysis road network configuration. Spatial data on Road Traffic Crash (RTC) was collected from the secondary data sources. Then spatial statistical analyses have been conducted to identify the relationship between RTCs and road configuration parameters using Geographic Information System (GIS) application. The correlation results indicated notable relationship between RTCs and Local Integration (r = 0.88, p < .01); RTCs and Connectivity (r = 0.77, p < .01); and RTCs and Choice (r = 0.76, p < .01). Accordingly, the study concludes that developed method based on network centrality analysis as a useful tool for transport engineers and urban planner続きを見る
