摘要

New traffic sensing devices based on wireless sensing technologies were designed and tested. Such devices encompass a cost-effective, battery-free, and energy self-sustained architecture for real-time traffic measurement over distributed points in a transportation system. A weather-resistant enclosure was designed and manufactured to protect the sensor from traffic impacts on the highway. This scalable technology can monitor traffic parameters such as flow, occupancy, point speed, and vehicle classification on road systems in real-time. The data collector device is also equipped with a memory card reader, which makes it suitable for temporary installation and short-term data collection. In addition to traditional traffic parameters, the sensors can measure and report the temperature of their surroundings because they are surface-mounted. The sensors developed as a result of this project are also capable of capturing a digital magnetic signature of vehicles within any intervals required by clients. The digital magnetic signature was processed to calculate traffic volume, vehicle speed, and vehicle length estimation for classification. With the help from SHA and Inter County Connector staff, five sensors were permanently deployed and thoroughly tested on a section of the ICC.
