| 摘要： | Until recently freeway traffic operations data were collected in house by the Ohio Department of Transportation (ODOT) using loop detectors that provide speed, flow and occupancy by lane. Ultimately, most real-time management applications only use the speed measurements (e.g., traveler information and congestion monitoring). In recent years a new company, SpeedInfo, emerged with a different paradigm for traffic operations data collection. The SpeedInfo approach is revolutionary in two ways. First, at the sensor level, they employ a single unit that can be strapped to an existing pole and configured in less than half an hour. The unit contains a Doppler radar to measure traffic speeds, a wireless modem, a solar panel, a battery, and an onboard processor. In principle they should provide very accurate speeds because of the radar sensor. Typically the units report speed in two directions (approaching and receding) every minute. The SpeedInfo sensor is attractive because it is completely wireless and out of the right of way. Second, the SpeedInfo business model is innovative. Instead of selling hardware, the company sells data, while the company typically owns and maintains the sensors. SpeedInfo collects the traffic data and covers the communications costs, they then sell the speed data. In effect SpeedInfo offers a viable opportunity to outsource traffic data collection. |
