The US Department of Transportation (USDOT) has released a summary of available vehicle-to-pedestrian (V2P) technologies. The objective of the technical scan was to review available literature and to scan existing technology to identify pedestrian collision warning applications and assess their suitability to be adopted under the Intelligent Transportation System Joint Program Office (ITS JPO) Connected Vehicle Program.
The scan and subsequent database outlines the current V2P technological landscape. In total, 86 V2P technologies have been identified. While a number of the technologies are camera-based (17), others are likely to gain traction as the broader technological landscape evolves-making more advanced devices more easily accessible and less expensive. The data base also include crowd-sourced technologies such as WAZE.
This database will be continually updated as new technologies become available. The most recent update to the database was completed in May 2015.
The scan searched existing databases, peer-reviewed journals, and the Internet to identify potential V2P technologies (i.e., communications approaches, devices, applications, and others) in the United States and abroad. In addition, industry and research professionals were contacted to more fully understand developing V2P technologies.
Technologies were not limited to passenger vehicles; the scan also included technologies for different vehicle types (personal vehicles, commercial vehicles/trucks, transit, public transportation vehicles including buses, light rail vehicles, etc.).
The majority of the V2P safety technologies identified incorporate some form of visual notification method. Although this form of notification/warning may be effective, it may take visual attention away from the roadway (for both pedestrians and motorists) at a time when it is especially critical, DOT noted.
Each of the existing and developing technologies identified are described and classified based on various characteristics such as:
- Detection method (e.g., cameras, eight sensors)
- Crash type addressed with technology
- Users alerted (e.g., pedestrian or bicyclist)
- Alert/notification type (e.g., mobile phone alert)
- Roadway characteristics where system may be used
- Environmental characteristics specifically addressed by the technology
- Interventions made by the technology.
The V2P Technology Database is presented in an Excel spreadsheet format. The first tab, “Summary Information,” contains summary data of each of the technologies discovered through the scan. Each of the subsequent 86 tabs includes detailed and linked information about each technology.
