Traffic Data Collection
Accuracy in traffic data collection is fundamental in that the resulting data serves as the foundation of planning for road, highway and bridge infrastructure. For this reason, State Departments of Transportation and other state and local government agencies, as well as private sector clients nationwide, recruit The Traffic Group’s Data Division for their traffic data collection programs.
The Traffic Group’s Data Division also serves as the foundation of our traffic engineering and transportation planning consulting work. By understanding prevailing traffic patterns and parking conditions, we develop strategies for optimizing the efficiency of on-site and off-site transportation operations for our clients. If you need traffic counting services, you need not look further than The Traffic Group’s traffic data collection experts.

FAQ
ALPR stands for Automated License Plate Recognition.
The road tubes that are placed do not automatically provide speed information. A set of road tubes versus one road tube is required and the computer that records the data must be appropriately configured to collect speed data.
We are undertaking traffic counts at the request of local Government to survey existing traffic conditions. This survey information is collected on a regular basis for Government to understand how traffic is growing or reducing along roadways. This information is used to make long-range projections for road improvements, for resurfacing of roadways, reimbursed by the Federal Government from gas tax revenues.
In congested areas, traffic volumes can be classified unless vehicles are at a stop or a crawl and there is gridlock.
Verification of data is undertaken many times by checking nearby intersection counts or undertaking manual traffic counts in the same area or at the exact location where the data is being collected. Therefore, both manual and machine counts are often undertaken at the same time to verify the accuracy of the machine data.
Under normal circumstances, mechanical or turning movement counts can be completed within one to two weeks of the request to collect the data, depending on the time of year, it is possible that it could take three to four weeks for completion and summary of the information.
A systematic process for the collection, analysis, summary and retention of highway and transit related person and vehicular traffic data.
Average Annual Daily Traffic – the average amount of daily traffic at a particular location of a road.
Automatic Traffic Recorder – device used to collect traffic count data. These machines are mini-computers powered by batteries or solar energy. The box is connected to a set of road tubes.
A vehicle classification count is used to determine the percentage of vehicles within the 13–15 class system set forth by the FHWA (Federal Highway Administration), whereas a volume count only determines total number of vehicles without regard to the type of vehicle (car, truck, bus, etc.).
