[HTT17-05] Evaluation Method for Pedestrian Bridges Based on Spatial Configuration
Keywords:Jaywalking, Spatial Configuration, Discriminant Analysis
1. Introduction
The Japanese government has reported the need for maintaining and updating infrastructure. Dangerous road crossings are a known problem, such as when pedestrian crossroads without using pedestrian bridges or crossings.
2. Objectives and Methods
The purpose of this study is to evaluate existing pedestrian bridges. We conducted fieldwork and discriminant analysis. First, we conducted surveys and analyses to clarify the relationship between pedestrian bridges and jaywalking. Next, we confirmed the reliability of first survey by observing an actual pedestrian bridge. In this study, jaywalking refers to crossing a road without using a pedestrian crossing or pedestrian bridge in Japan.
3. Relationship Between Jaywalking and Road Spatial Elements
The purpose of this survey and analysis was to identify which road spatial elements, such as pedestrian bridges, are related to jaywalking.We targeted 19 locations with jaywalking and 6 locations without jaywalking, analyzing 8 road spatial elements as explanatory variables.As a result, we found that the number of lanes, distance to the pedestrian bridge, and traffic volume are related to jaywalking, in that order.
Next, we targeted 21 sections with jaywalking and 18 sections without jaywalking. We defined the space between crosswalks as a "section". We also selected new road section elements and analyzed their relationship with jaywalking. The results indicated that there was a significant relationship between jaywalking and explanatory variables. Additionally, we developed an equation to predict jaywalking.However, we found that the relationship between jaywalking and the time to cross a pedestrian bridge was weak. Therefore, we considered that it is possible to evaluate pedestrian bridges by combining predictions of jaywalking with other factors.
4. Evaluation of Pedestrian Bridge Usage
We compared the evaluation categories from two documents related to cases of pedestrian bridge removal. We focused on the purpose of the pedestrian bridge and the direction of pedestrian movement. We investigated these factors on a map along with the predicted occurrence of jaywalking.
We hypothesized that the pedestrian bridge would be primarily used for commuting to work or school. Using GIS, we clarified the location of schools, train stations, and pedestrian bridges. The study was conducted in Asahi Ward, Osaka City.
Our analysis showed that pedestrian bridges tend to be located between schools and train stations. This suggests that people travelling to these locations tend to use pedestrian bridges. However, we also observed that some pedestrians jaywalk in order to avoid using pedestrian bridges.
We predicted jaywalking for several sections surrounding the Omiya Pedestrian bridge in Asahi Ward, Osaka City. We predicted that jaywalking would occur in all target sections. This suggests that the ease of jaywalking around a pedestrian bridge is an important factor in determining the effectiveness and necessity of the pedestrian bridge.
5. Conclusion
This study found that certain road space elements are related to jaywalking. Through analysis, we were developed an equation to predict jaywalking. However, the relationship between the equation to predict jaywalking and pedestrian bridges was weak. We concluded that it is possible to evaluate pedestrian bridges by combining the jaywalking prediction equation with other elements. In future research, we plan to investigate the psychological burden that pedestrian bridges may impose on people.
