The following is a list of projects and publications that Transit Mobility researchers are currently working on:
Denton County Transportation Authority Title VI Technical Assistance and Innovation Research, 2018 – Present
TTI will conduct research to compare an innovative geo-spatial demographic analysis technique for assessing transit service changes with DCTA’s current Title VI service change analysis methods. The innovative method streamlines the service change analysis process and accounts for service performance and equity of service access concurrently, presenting an opportunity to improve service efficiency and enhance equity at the same time. As part of this project, TTI will provide technical assistance to conduct standard Title VI equity analyses for DCTA’s upcoming proposed service and fare changes to develop a baseline service change analysis for comparison with the innovative method. TTI will assess the innovative method and determine its effectiveness to better inform DCTA staff about potential adverse and inequitable impacts of service changes during the planning and development of such changes. If the innovative method if found to be effective DCTA will have the option to introduce a well‑vetted alternative method for assessing service efficiency.
TCRP Synthesis SA-47: Bus Transit Signal Priority – Current State of the Practice, 2018 – Present
Bus Transit Signal Priority (TSP) is an important tool that increases bus speeds and reliability, thereby improving transit system efficiency and effectiveness. Transit agencies implement a wide variety of TSP strategies and parameters and report different levels of benefits from TSP implementations in various traffic conditions and right-of-way treatments (e.g. mixed vs. dedicated guideway). This synthesis study documents the current practice of transit systems’ use of TSP to meet the different objectives under diverse conditions; it provides an overview of 1) TSP strategies and parameters, 2) the resulting benefits and 3) an assessment of to what extent the disparity in benefits realized are driven by strategy and parameter choices. Data were collected using a literature review focusing on modern deployments (both domestic and international), a survey of selected North-American transit systems that utilize TSP, and case examples.

Denton County Transportation Authority, Multi-Modal Service Cost Allocation Model, 2018 – Present
Produce a model that allocates variable and fixed operating expenses and capital asset replacement expenses to each of DCTA’s services using industry best practices and federally-accepted procedures.
Capital Metro, Transit Signal Prioritization System Functionality Assessment, 2018 – Present
Assess the functionality of the transit signal prioritization (TSP) system for two bus rapid transit lines. Determine system functionality by merging large, transactional data sets from the transit agency’s CAD/AVL system and the city’s traffic management system and comparing TSP transactions against system specifications.
VIA, Paratransit Fleet Fuel Alternatives Analysis, 2018 – Present
Compare the cost of ownership for a propane- versus gasoline-fueled paratransit fleet. Research will: 1) review industry practices and experiences and 2) incorporate established life cycle cost models.
TCRP IDEA T-91: Comprehensive Wayfinding for All (CWall), 2018 – Present
Develop and test a prototype CWall smartphone application (app). CWall is an accessible smartphone app that will provide transit and pedestrian trip planning and navigation assistance along the entire transit trip. CWall will aid users in traveling to bus stops, locating them using accessible pathways, obtaining real-time transit information, and receiving alerts for when to board and get off buses. Although CWall specifically targets users with disabilities, the app will also benefit users without disabilities by reducing the learning curve of taking transit and making the sidewalk and transit network easier to understand and use. Learn more about the project.
Sun Metro, Mass Transit Fare Equity Analysis, El Paso, TX, 2018 – Present
Sun Metro, in El Paso, TX, is considering adjustments to its fare policy. TTI is helping Sun Metro understand the Title VI implications of the fare changes and is providing information about fare collection technologies and current practices for regional fare collection.
TxDOT, Phase One – Identify and Evaluate Existing TNCs Used as a Part of Basic Mobility, 2018 – Present
Provide technical assistance to support the TxDOT Public Transportation Division to evaluate the role of Transportation Networking Companies (TNCs) in providing basic mobility. TxDOT wishes to draft a call for proposals to develop pilot projects to demonstrate how TNCs might be used to support public transit operations. TTI researched existing partnerships between transit agencies and TNCs and documented lessons learned, issues, and opportunities for pilot projects.
VIA Level of Service Index and Map, 2018 – Present
Develop a Level of Service (LOS) Index calculated from several rider-oriented metrics for VIA’s bus routes. Assist VIA in developing the LOS metrics, weighting the metrics, calculating the LOS Index, and visualizing the results on an interactive map.
Houston Metro, METRO ADA Wheelchair Securement – Practices and Opportunities, 2018 – Present
Document existing METRO practices and conditions, regulations for wheelchair securement, user experiences of securing wheelchairs, national practices for wheelchair securement, and opportunities for improvement. The findings from this research will assist METRO in developing future procurements and ensuring the agency’s operator trainings match the state-of-the-practice.
Denton County Transportation Authority, Strategies for Improving Performance Data Reliability, Validity, and Reporting, 2017 – Present
Provide technical assistance, system and data analysis and assessment, and best-practice guidance to enhance performance reporting and management processes in order to: (1) improve the quality of data used in performance reporting, (2) enhance the presentation and reporting of performance metrics, and (3) expand the usefulness of performance data for management decision-making.
El Paso County, Transit Feasibility Study, 2017 – Present
Perform a feasibility study of a regional transit system serving all of El Paso County. Analyze existing conditions, assess unmet transit need, determine possible transit service scenarios, and identify potential funding and governance options.
TCRP Synthesis SF-20: Managing the Transit Scheduling Workforce, 2017 – Present
Document the current state of practice regarding how transit agencies manage transit scheduling human capital and examine how transit agencies are recruiting, training, developing, and retaining schedulers. The final report is currently in preparation for publication.
Innovative Concepts to Inform First / Last Mile Planning, 2017 – Present
Conduct an inventory of the sponsor’s current and potential service areas to assess trip travel patterns and areas of transit need to identify places that may be appropriate for innovative mobility options to mitigate service duplication, create more cost-effective service, and integrate new innovative services within the sponsor’s service portfolio. To assess the potential for addressing transit need with innovative and/or new services, TTI will document: 1) Operating characteristics of each option; 2) Existing service providers (including an assessment of each provider as a solution); 3) Concepts, strategies, and policies for fare payment and policies for innovative services. TTI will use findings to develop potential service scenarios and create a methodology to assess/rank these scenarios as solutions to the sponsor’s first/last mile challenges.
Sun Metro, Mass Transit Procurement Assistance, 2017 – Present
Assist the City of El Paso in its process to establish new contracts with a private company for transit management and operations. Work as an independent third-party facilitator and assist the City by evaluating different approaches to managing and operating Sun Metro transit services before developing a new request for proposal and by assisting with the procurement process as required. TTI has assisted the City in similar services since 2006 and provided historical perspective, continuity, and efficient services.
