| 摘要： | The Texas Department of Transportation (TxDOT) operates Traffic Management Centers (TMCs) in several Texas cities, and there are plans for adding more TMCs throughout the state as well as for expanding the capability of the existing centers. Each of these centers is tasked with an operational role to manage and operate TxDOT roadways within its region. This management is accomplished in part by monitoring traffic data from many TxDOT-funded resources such as closed-circuit television (CCTV) surveillance cameras, freeway operational data (video detection systems, automatic vehicle identification systems, loop detectors, etc.), and roadway incident information. TxDOT has provided public access to much of this information free of charge via the Internet; this has proved to be a very successful endeavor. Recently, private entities, such as the media and traffic information service providers (ISPs), have requested direct access to this traffic information as well as to live video feeds from the roadway CCTV cameras. The ISPs typically repackage this information, add value and features to the data, and subsequently charge a fee to travelers, media outlets, and other private customers for the information. Although some TxDOT TMCs are providing traffic information access for their regions to the private sector, there are no guidelines and procedures to provide statewide consistency among the existing and planned centers. |
