1. Measuring Transit-Coverage Level- Of-Service in U.S. Border Cities Luis David Galicia, Ph.D. Texas A&M Transportation Institute https://plus.google.com/108921303273699318714/photos?hl=en

2. Overview of Presentation Background and Problem Statement Literature Review Case Study Hypothesis Data Collection Methodology Results and Conclusions 2

3. Background A similar concept, Service Coverage-Level Of Service (SC-LOS), was adopted in the first edition of Transit Capacity and Quality of Service Manual (TCQSM) in 2004 The LOS is divided in 6 categories being “A” the highest and “F” the lowest 3

4. Service Coverage is defined by the TCQSM as “the availability a potential transit user has to access the transit system within a reasonable walking distance (typically ¼ of a mile) from the user’s origin or the user’s final destination” 4 0.25 mile

5. Problem Statement Is the SC-LOS suitable for border cities/regions in the U.S? 5 Source: The El Paso del Norte Group

6. 6 What the Literature Says.. Transit Supportive Area (TSA) concept* is included in TCQSM- Chapter 3 (2 nd Edition) and Chapter 5 (3 rd Edition) “Fixed- Route Transit Service Measures” *Pushkarev, B., J. M. Zupan. Public Transportation and Land Use Policy. Bloomington, IN. Indiana University Press, 1977 Source: TCQSM 2nd Edition

8. Hypothesis Even though the TCQSM and TLOS help planners shape the areas that support transit route coverage, these methodologies might not lead to the most accurate results at border cities/regions The TSA concept might “exclude” transit riders that have their work-base trips originated in other areas 8

16. TCQSM (2 nd Edition) vs TCQSM (3 rd Edition) 16

17. Conclusions The hypothesis was confirm via the suggested methodology The occurrence of work-based trip attraction at TAZs with almost no employment suggests that the work trips are for household services The portion of TSAs covered by the transit service increased by approximately 5% just by adding some TSAs with relatively high passenger volumes (although these TSAs have low household density or employment) TCQSM’s TSA and SC-LOS determination methodology may not cover border regions with special trip generators or attractors, such as the one presented in this research 17

18. Further Analysis Refinement of actual walking distances Use of other border cities with similar conditions as case studies (USA-MEX and USA- CAN) Use of up-to-date ridership data Suggestions? 18
