Waze is a smartphone app that offers real-time smart route alternatives to help drivers avoid congested freeways. In Los Angeles, Waze often directs drivers to side streets through upscale neighborhoods, so surface streets in neighborhoods also become congested with traffic.
Because Waze uses crowdsourcing to report traffic, residents are uniting to report congestion in their area so cars are rerouted to other streets… and back to the freeway.
