The overall goal of the SPaT Challenge program is to challenge state and local public sector transportation infrastructure owners and operators (IOOs) to deploy DSRC infrastructure with SPaT(and MAP) broadcasts in at least one corridor or network (approximately 20 signalized intersections) in each state by January 2020. Updates on project planning, procurement, installation, testing, and operations are periodically posted on the NOCoE website with cooperation from the American Association of State Highway and Transportation Officials (AASHTO), the Institute of Transportation Engineers (ITE), and the Intelligent Transportation Society of America (ITSA) and the Federal Highway Administration (FHWA).
SPaT Challenge Webinar Series Webinar #7 included updates from Blain Leonard (Utah DOT), Joanna Wadsworth (City of Las Vegas), and Liz White (Virginia Tech Transportation Institute).
The following recommendations were discussed:
- Use industry standards when planning DSRC communication links between intersection signal controllers and roadside units (RSU). Field experience shows RSU DSRC ranges can exceed 300 meters.
- It will be challenging to integrate connected vehicle system elements into existing systems. Use a project master schedule to detail the timing of installation and integration activities.
- Working in high-profile traffic environments will elevate levels of scrutiny on security, testing, and management of fielded units.
- Remote monitoring and management capabilities can save time.
- MAP files take significant time and effort to develop and validate.
