Creating Livable Communities through Connecting Vehicles to Pedestrians and Cyclists

John MacArthur, Portland State University


Safety of pedestrians and bicyclists is a significant problem in U.S., with 4,743 fatalities and 76,000 injuries of pedestrians and 726 fatalities and 49,000 injuries of bicyclists in 2012 (NHSTA 2014a & b). Establishing and creating livable communities relies on making walking and bicycling as safe and convenient as possible. The U.S. DOT has embarked upon a major research program toward implementing connected vehicle safety technologies, applications and systems using short-range communication technologies (e.g., DSRC). Connected vehicle (CV) safety applications are designed to increase situational awareness and reduce or eliminate crashes through vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) data transmission that supports: driver advisories, driver warnings, and vehicle and/or infrastructure controls (U.S. DOT 2014a & b). These technologies may potentially address up to 82 percent of crash scenarios with unimpaired drivers, preventing tens of thousands of automobile crashes every year. Additional benefits will be in the broad areas of safety, mobility and environmental.

As connected vehicle research moves from research and pilots into deployment and test-beds, cities need to be prepared for vehicles and infrastructure with DSRC and other wireless communication connectivity. States, regions and cities will benefit from initial scoping, evaluation, and assessment of the impact of connected vehicles and infrastructure and a range of potential cooperative system applications. CV applications have a great potential to fundamentally transform the development and deployment of your future transportation system and communities. Most of the research and implementation projects have focused on V2V and V2I applications that improve mobility and vehicle safety, with some focus on pedestrian-vehicle conflicts (U.S. DOT 2014b). Some of those applications are Red Light Violation Warning, Blind Spot/Lane Change Warning, Right Turn Warning, Mobile Accessible Pedestrian Signal System. Vehicle-to-People (V2P) or V2X applications have not been as extensively developed and tested as other CV applications. How can these technologies and applications, such as DSRC, be used by pedestrians and cyclists to improve their safety and reduce vehicle conflicts? Can access to travel information improve mobility options and achieve environmental outcomes? This project will explore the linkages and opportunities with connected vehicles and infrastructure to pedestrians and bicycles. Building on U.S. DOT exploratory research in this area, this project will assess current V2P applications, the state of the knowledge, barriers, gaps, current applications and develop a research agenda.


This research is looking at the different use cases where connected technologies could be used with bicycles. By employing these technologies, barriers to cycling could be broken down and the cycling environment could be made safer. By understanding the potential of these technologies, cities can look to deploy technologies to promote the use of sensors and other devices.
