Abstract:Recent data show that the greatest proportion of pedestrian fatalities occurs at non-intersection locations, where physical and electronic infrastructure required to support dynamic safety treatments are less common. To address this gap, the Federal Highway Administration (FHWA) and Intelligent Transportation Systems Joint Program Office (ITS JPO) developed a vehicle-to-pedestrian (V2P) smartphone application that allows pedestrians to signal their intent to cross midblock, which triggers an in-vehicle warning to nearby drivers. Previous testing at a closed track with participant drivers indicated that the in-vehicle warning, communicated via dashboard-mounted smartphone, encouraged drivers to yield at marked midblock crossings. The current research expanded on previous work by evaluating pedestrians’ perceptions and use of the FHWA smartphone application to signal their intent to cross at a marked midblock crossing. First, feedback from focus group interviews was used to improve the application interface to support proper use. Subsequent field tests conducted at three live crossing locations indicated that participants used the application as intended without significant changes in crossing behavior relative to a nonconnected smartphone-based alternative. Future work may explore interactions between drivers and pedestrians using the application in relatively controlled, urban-like settings, such as a university campus.
