Synthesis of Information Related to Transit Practices. Topic SD-07. Red Tinted Bus Lanes Experience

Bus lanes have been around for decades and were initially identified with white pavement markings. Tinted pavement bus lanes first surface in international cities. In the US, city bus lanes conformed to signage and markings described in the Manual for Uniform Traffic Control Devices (MUCTD). This began to change in 2017 with pilot tinting allowed by the Federal Highway Administration (FHWA) and was formally approved by the FHWA in 2020. Since then, many cities have implemented red tinted bus lanes as part of both bus rapid transit (BRT) projects and non-BRT bus lane projects. The expansion of the concept suggests wide success, but little is known about their successes/failures and policy, technical and operational issues. How do tinted bus lanes compare to physically separated exclusive BRT lanes? What have been key factors to the success of the painted bus lanes and what are the key challenges? Observations in San Francisco indicate that right turning motorists better understand the red tinting and that enforcement is critical to their success. Other regions are exploring this approach as a means to help motorists better navigate an increasingly multimodal arterial cross-section. Foundational questions remain - are the tinted lanes safer, do they improve operations and how important is enforcement? The objective of this Synthesis is to document the current state of practice in the performance and implementation of red tinted bus lanes.
