Many jurisdictions have turned to innovative parking management strategies as a way to address congestion in urban areas since the time spent circling for on-street parking increases congestion and emissions. By decoupling pricing from parking information, this project develops a methodology that uses parking turnover and occupancy data to provide drivers with information about available on-street spaces. The parking availability information will be broadcasted via dynamic on-street wayfinding as well as mobile apps. On-street information allows the drivers to find available parking without taking their eyes off the road to use a mobile device; however, mobile apps are beneficial for trip planning and also when drivers can rely on passengers to safely disseminate information or when information is provided via voice commands. On-street parking information has the added benefit of being more equitable as it does not rely on the adoption of smartphone technology.
