Liquid Asphalt

The Charlotte Department of Transportation (CDOT) uses liquid asphalt in the repair and construction of asphalt streets, including pavements, potholes, utility patches, and street paving.  CDOT requires a local pickup facility within Mecklenburg County due to material storage requirements. Local pickup provides the flexibility to secure small and large quantities of material as needed.

Sodium Chloride Salt

The City of Charlotte requires Sodium Chloride Salt for deicing of City streets and roads, and as a preventative measure for any anticipated snowy or icy street conditions.   This solicitation is to provide bulk tonnage delivery of Sodium Chloride Salt that has been treated with anti-caking agent to the addresses specified by Charlotte Department of Transportation (CDOT).

Traffic Signal Performance Measures

Automated Traffic Signal Performance Measures shows real-time and a history of performance at signalized intersections. The various measures will evaluate the quality of progression of traffic along the corridor, and displays any unused green time that may be available from various movements. This information informs CDOT of vehicle and pedestrian detector malfunctions, measures vehicle delay and lets us know volumes, speeds and travel time of vehicles. The measures are used to optimize mobility and manage traffic signal timing and maintenance to reduce congestion, save fuel costs and improve safety. Currently, the City has a 200 intersection pilot studying how performance measures can assist us in proactively monitoring our traffic signals. This project would be to identify the software solution the City will use Citywide and install.
