SYSTEM FOR SENSING ROAD AND TRAFFIC CONDITIONS
First Claim
1. A traffic sensing system for collecting information on traffic conditions, the system comprising:
- a traffic sensing server for receiving traffic reports from mobile traffic sensing devices and providing aggregate traffic reports from the received traffic reports; and
a plurality of mobile traffic sensing devices for sensing traffic-related information near the devices and sending traffic reports to the traffic sensing server, the mobile traffic sensing devices including an accelerometer and a cellular communication device, a component that determines the orientation of the accelerometer, a component that samples the accelerometer, and a component that derives traffic-related information from the accelerometer samples.

Abstract
A traffic sensing system for collecting information on traffic conditions is provided. A traffic sensing system includes a traffic sensing server and a mobile traffic sensing device that sends traffic reports to the traffic sensing server. An MTS device may use an accelerometer integrated into a smart phone to detect potholes, to detect when the vehicle is braking, to detect whether the MTS device is being transported via a vehicle or a pedestrian, to detect horns sounding, and so on. The MTS device reports the various conditions to the traffic sensing server for accurate assessment of traffic conditions at stretches of road through which vehicles transporting MTS devices travel.
