Waze is a project to create interactive, user-generated road maps with Real-Time Road Information. Waze maps will be dynamic and contain information on traffic, road construction, accidents & incidents, police traps & speed cams, available parking and more.
Driving with Waze mobile client lets users passively and actively share real time data and receive the optimal route to their destination.
Waze has launched on 3 weeks ago on android phones, but are now looking for Windows Mobile users to join their alpha program.
