Today I heard there was a traffic jam at Cienega going toward the village.
I had previously seen a traffic alert pop up on my Google Maps on Android phone when there was contruction hold up at the dam. Today I was excited to see detailed traffic speed along highway 18 from San Bernardino to Cushionberry grade! Right on my phone!
It looks like the car show is causing a huge weekend traffic jam coming into Big Bear Lake!
How does google do real time traffic?
Via "crowdsourcing", everyone who is using google maps with My Location feature enabled is sending google anonymous user data about their speed and location. Google aggregates this all together into a real time view of traffic of surface streets.
I think that since cell tower service on the 38 and Cushionberry grade is spotty google can't get enough data for those roads. But highway 330/18 has good cell service and on a busy weekend their was traffic data from San Bernardino on 18 all the way to Cushionberry grade!
