Analyze the Use of Green Pavement Markings: Intersection Safety for Non-Motorized Users

TxDOT has not applied for MUTCD Interim Approval for the Green Colored Pavement (IA-14) but individual jurisdictions within Texas have applied for and received approval under IA-14, including Austin, El Paso, McAllen, Odessa, and Ft. Worth. Local TxDOT districts are required to respond to the local agency’s request. These positions may vary by district and require staff to investigate and to perform the due diligence to develop a position on the proposed application. TxDOT currently holds no position or data to evaluate the use of green-colored pavement at intersections to increase safety. This lack of data not only affects the safety of bicyclists but also hinders the planning and design of traffic devices to improve safety, and the inconsistent application of green pavement markings throughout Texas undermines the goal of uniform traffic control devices. This research will provide on-the-ground evidence on the impact of green colored pavement at intersections on safety. This research will provide TxDOT with the necessary input to either apply for MUTCD Interim Approval for the Green Colored Pavement (IA-14) and/or respond to FHWA’s request for TxDOT’s official response to cities’ request for MUTCD interim approval. The researchers will evaluate usage by bicyclist and pedestrian approaches and provide at least two pilot locations- likely in Houston and Austin. The research approach may include bicycle and pedestrian counts, STRAVA crowd-sourced pedestrian and bicyclist data (already purchased by TxDOT), questionnaires, as well as observational surveys of pedestrian, bicyclist and motorist behaviors. These activities might be collected at intersections with green-colored paint and at control intersections without green paint. The research will be used to provide a report with recommended best-practices on the implementation of green-colored paint and as a cost-benefit analysis of the usage of green-colored pavement markings to improve safety for non-motorized users. The research report will document the findings of the research, including new safety prediction models and updated features within the TRSD
