Crowdsourced traffic calming

We present our work on creating key elements of a Crowdsourced Traffic Calming system as an enabler for nonspecialist citizens to engage in traffic measurement and evaluation in their own communities. We present our design of a roadworthy, low-power, wireless Traffic Sensor; deployment of a low-cost, wide-area sensor network supporting efficient and economical gathering of traffic and other smart city data; a set of browser-based visualization tools for analyzing acquired traffic data; and a set of related studies to optimize the communication and energy performance of sensor within the context of this new network. We discuss the challenges uncovered while deploying this system and hindrances that may be encountered by other city-scale, traffic-related studies.
