Tire debris is one of the most common and prominent type of waste that can be observed on roadways. However, the extent and implications of this type of debris remain largely unknown, particularly in Texas, where there is a perception among the public that tire debris may represent safety, congestion, and maintenance concerns. Currently, traffic activity generates tire debris on Texas highways at an unknown rate. This debris must be removed as part of programs run by state and local agencies, such as maintenance or roadside emergency response. The costs associated with these operations are undetermined to a large extent. The true extent of the process of debris generation, the safety, operational, and economic ramifications are also unknown. The Performing Agency shall survey, collect field data, and review crash records in order to produce essential information on the following points: (1) the volume of tire debris that is generated in Texas highways each year, (2) the cost to state and local stakeholders of collecting and disposing this type of debris, and (3) the safety and economic impacts to Texas road users associated with tire debris. In summary, the objective of this project is to develop statewide metrics of the volume, rate of generation, economic implications, and safety impacts of tire debris in Texas highways. |
