Baton Rouge, La. – The Louisiana Department of Transportation and Development (DOTD) is notifying residents and motorists that traffic count devices are being temporarily installed on various local roads across the state. Data collection is currently underway in several parishes, including Caddo, Sabine, St. John, St. Martin and Red River.
These devices are used to collect valuable information on traffic volumes, vehicle types and roadway usage patterns. The data supports future decisions related to transportation planning, infrastructure improvements and maintenance priorities. While DOTD has conducted traffic monitoring for decades, some of the current locations have not been surveyed in more than 20 years.
The equipment is non-invasive and does not pose a risk to the public or vehicles. Typically, traffic counters appear as small electronic devices placed near street signs or along the right-of-way. DOTD asks the public not to tamper with or remove the devices to ensure accurate data collection.
This effort is part of DOTD’s annual traffic monitoring program, which feeds into the Federal Highway Administration’s Highway Performance Monitoring System (HPMS). The collected data is used to calculate vehicle miles traveled, determine highway classifications, establish project design standards and evaluate levels of service across Louisiana’s road network.
DOTD thanks the public for its cooperation as the department continues working to enhance the safety, efficiency and reliability of the state’s transportation system.
