2. The optimization of the current City of San Marcos and Texas State University Bicycle System
Prepared by: T.R.A.N.S.

3. Scope Texas State University Population: 44,781 / 27,171 (2005)
Location: San Marcos, TX
Texas State University
Population: 44,781 / 27,171 (2005)
Median Age: 22.7
City Area: over 25 square miles
Focus: City Master Plan
Campus Master Plan

6. Introduction
Texas State University (TxState) has a student population of over 27,000 and growing and the City of San Marcos is seeing substantial growth
A survey completed for the City of San Marcos showed that new bike trails and lanes are the second highest priority for city development

7. Summary
The Texas State University master plan, widely promotes the development of an campus bike system
The City of San Marcos plans on developing the city into a bike friendly city with multiple bike lanes, routes and off road tracks

8. Purpose Examined the current bicycle infrastructure
and proposed new additions based on
impediments to a bicycle network
Bicycling for Transportation
Starting Points: Student Addresses and Census
Blocks
Destinations: High Flow Facilities, Central
TxState Campus
Problematic Areas
Traffic- Flow, traffic light wait time &
RR wait time
Terrain- distance & slope

9. Data Transportation: Demographic: Physical: Roads Bus routes Bus stops
Stop lights
Existing bike routes
Traffic flow
Traffic accident occurrences
Railways
Railroad crossings
Sidewalks

All data was defined and analyzed using Environmental Systems Research Institution (ESRI) ARCGIS Desktop 9.1 and the Spatial Analyst extension.
Deliverables utilized Microsoft Office Suite, Adobe Acrobat 5.0, Macromedia Studio 8, and Roxio Easy Media Creator 8.

11. Literature Review CURRENT TRANSPORTATION PROBLEMS
HOW THE PROBLEM OF TRANSPORTATION AFFECTS SAN MARCOS
ALTERNATIVES
SAN MARCOS AND A BIKE PATH NETWORK: A GOOD FIT
IT CAN WORK: USING DAVIS, CALIFORNIA AS AN EXAMPLE
HOW WOULD SAN MARCOS CITIZENS BENEFIT?

15. Methodology Data was spatially defined using the North American Datum
of 1983 and the projected coordinate system:
NAD_1983_Stateplane_Texas_Central_FIPS_4203_Feet
The first objective was to prioritize the areas of greatest
need
Divided analysis into two segments of population groups
- Non-resident Students
- Residents determined by census block demographics
Identified constraints that needed to be overcome
Identified areas that can be used in their current state and areas that
needed expansion or improvements
TRANS examined the current infrastructure and integrated our
findings into a final plan for recommendation

18. Results A majority of our least cost routes did not follow major roads
Aquarena Springs Dr and Ranch Road 12 were identified as the highest ‘cost’ (safety, difficulty, time) roads.
These avoided roads are primate candidates for bike lanes.
Bike lanes have been proposed on several of the roads that we found to be high cost.
Several proposed bike lanes were identified as low cost roads under the current infrastructure and should be lower priority.

24. Discussion Limitations to San Marcos Bike Network.
- Distance, Slope, non-landscape
impediments
Five major areas of student locations outside of TxState campus: Post Rd., Aquarena Springs, North LBJ, RR12, and Wonder World
Cost of new bike lanes and/or routes: $7,758,308 based on 45 miles of new bike lanes
Extensive research uncovered no previous studies on bicycle analysis that would have provided a blueprint for guidance

25. Conclusion
Both the City of San Marcos and TxState have implemented bike networks into their master plans
TxState campus master plan, calls for limiting car transportation through campus
This data can be used for determining the safest and most efficient routes for bike trails in San Marcos and the TxState campus. The results can be used to study transportation needs and obstacles of San Marcos. This will allow sound decisions to be made for future growth and expansion of both San Marcos and TxState.
Bicycle analysis is very objective and open to individual interpretation
