The Departments of Transportation (DOT) in several states in the United States use vehicle counters/classifiers to collect traffic volume and vehicle classification on their roads and highways. This data is extremely useful for designing pavement and planning new highways and roads. Designers and engineers use the data in their models to optimize design tradeoffs, e.g. up front investment in durable pavement materials vs. accrued maintenance costs over time, also whether or not to rebuild/expand a road or continue to incur ongoing maintenance costs. Vehicles classification information is stored in the vehicle. When a vehicle passes a roadside unit, information is transmitted to a roadside, base station (BS) unit. The BS will then pre-process and organize the data for simple data management at the Data Center. where the pre-processed data will be analyzed, decisions will be made, and/or results at points of interest with be reported.
