Lesson Background HTML

Location accuracy is a key requirement for the Connected Vehicle (CV) Pilots as Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) technologies are deployed into the field in larger quantities. The deployment area of the New York City Department of Transportation (NYCDOT) CV Pilot project presents challenges for GPS that the team has had to work hard to overcome to ensure that the in-vehicle devices can establish their locations with sufficient accuracy to utilize their CV applications. 

In the City’s urban canyons, there are fewer satellites visible due to the many skyscrapers, causing the GPS signal at ground level (that is needed to derive location) to be degraded or lost, either through satellite signals being obscured or through signals bouncing off surroundings and forming multiple paths as they reach the street (or canyon floor).
