Measuring Pedestrian Exposure Using Personal Electronic Devices
| 项目名称： | Measuring Pedestrian Exposure Using Personal Electronic Devices |
| 摘要： | Lack of pedestrian exposure data makes it difficult to understand changes in pedestrian crash rates. While the changes may be due to increases or decreases in exposure, there are a variety of other factors that can influence the changes such as congestion, infrastructure, and pedestrian age and impairment. The inability to separate exposure changes from other factors impairs the ability to design effective countermeasures programs to reduce pedestrian crashes. This project would measure pedestrian exposure using personal electronic devices, such as cell phones or global positioning system (GPS) devices. The first phase of the project will identify existing sources of pedestrian location data to see if any of these sources can be mined for travel data and will develop an operational definition of pedestrian exposure. If possible, use the existing data to develop measure pedestrian exposure. If a good source of location data is not available, an app will be developed for participants to install on their personal cell phones or a device will be distributed to participants to obtain location data. The data will be anonymous and aggregated to discern potential exposure to vehicles. The next step of the project will be a small pilot study to recruit participants and collect exposure data. |
