APPENDIX A
Survey Questionnaire

Introduction

The Texas A&M Transportation Institute is conducting a synthesis for the Transit Cooperative Research Program (TCRP). TCRP Project J-07/Topic SD-07 is documenting the current state of practice in the implementation and performance of red-tinted bus lanes. The synthesis is focused on:

  • Understanding why transit agencies and jurisdictions such as cities (collectively referred to as “agencies” hereafter) have implemented red-tinted bus lanes
  • Documenting the key features of red-tinted bus lanes
  • Understanding how much it costs to plan, implement, operate, enforce, and maintain red-tinted bus lanes
  • Understanding the impacts of red-tinted bus lanes
  • Documenting how red-tinted bus lanes have been enforced and what enforcement strategies have been effective
  • Documenting the maintenance performance of red-tinted bus lanes
  • Understanding the partnerships involved in planning, implementing, operating, enforcing, and maintaining red-tinted bus lanes
  • Identifying the key challenges of planning, implementing, operating, enforcing, and maintaining red-tinted bus lanes
  • Documenting lessons learned that would be valuable to other agencies implementing red-tinted bus lanes

For the purposes of this study, red-tinted bus lanes are defined as travel lanes that feature red-colored pavement to enhance the conspicuity of locations, station stops, or travel lanes in the roadway exclusively reserved for vehicles of public transit systems or multimodal facilities where public transit is the primary mode. This definition is based on Section 3H.07 of the 11th Edition of the Manual on Uniform Traffic Control Devices (MUTCD). The red color treatment can be achieved using tinted paving materials (e.g., colored asphalt), paint, or other materials applied to the surface of the road. It can be applied for the full length of a bus lane or only at locations such as intersections and bus stops.

We estimate that it will take 20 to 40 minutes to complete this survey. If you leave the survey and return to complete it later, you will be able to continue where you left off if you use the same device and browser. Your answers will be saved every time you advance to the next page of the survey. We encourage you to collaborate with your colleagues and external partners when completing the survey. Please feel free to forward the survey link to your external partners.

This survey must be completed by 11:59 p.m. EST on March 25, 2024. The information you provide in response to this survey will be synthesized with information collected from other agencies that have implemented and/or use red-tinted bus lanes. Your answers will be confidential to the extent possible. Your participation in the survey is voluntary at all times.

About Your Red-Tinted Bus Lanes

Full and intermittent red-tinted bus lanes are illustrated in the figure that follows. Cases A and C are full red-tinted bus lanes. Case B is an intermittent red-tinted bus lane (i.e., red-tinted bus lanes only at locations such as bus stops and intersections).

How many lane-miles of full red-tinted bus lanes are in your jurisdiction/service area? (If red-tinted bus lanes are present in both directions on a 1-mile long roadway segment, that would be 2 lane-miles.) Enter “0” if none.

An illustration shows three roadway layouts labeled A, B, and C.
Long Description.

The layout A shows a bus-only lane with red pavement marked ‘ONLY BUS’ and ‘STOP BUS’, along with a ‘BEGIN RIGHT TURN LANE’ (R3 to 20) sign and a ‘RIGHT LANE BUSES ONLY 6 AM to 9 AM MONDAY to FRIDAY’ (R3 to 11 Series) sign. B shows a bus-only lane at terminals or station stops with red pavement marked ‘ONLY BUS’, a designated waiting area, and ‘RIGHT LANE BUSES ONLY 24 HOURS’ (R3 to 11 Series) signs. C shows a buffer-separated bus-only lane with red pavement marked ‘ONLY BUS’, a ‘BEGIN RIGHT TURN LANE’ (R3 to 20) sign, and ‘RIGHT LANE BUSES ONLY 24 HOURS’ (R3 to 11 Series) signs. A legend indicates direction of travel, and notes reference Chapter 2G for preferential lane signs, Chapter 3E for preferential lane markings, and states that the use of colored pavement is optional.
