In order to meet the transportation demands of population, employment and economic growth, the City developed the Transportation Master Plan, which consists of two basic elements, a roadway element and a bicycle/pedestrian element. Future updates of the Transportation Master Plan will consider all transportation modes including roadway expansion, high-occupancy vehicle lanes (HOV), transit options and bicycle/pedestrian facilities. The transportation plan is presented as an Ultimate Roadway Network and a Roadway Table. The network shows existing and planned arterials, which include bicycle facilities, for the ultimate growth of the City.
The Transportation Master Plan encompasses the transportation system within the city limits as well as the extraterritorial jurisdiction (ETJ). The City also coordinates with our regional planning partners.
- Ensure that the citizens of Round Rock are afforded an adequate future transportation system.
- Ensure the efficient utilization of the dedicated 1/2 cent sales tax.
- Identify the major deficiencies in the existing transportation network.
- Evaluate the existing transportation network.
- Identify current and future land uses and travel patterns, as well as, population and employment forecasts.
- Identify environmentally-sensitive areas.
- Develop roadway design standards.
- Incorporate citizen participation into the planning process.
- Identify the necessary transportation network improvements.
- Develop a short term (2010), a long term (2020) and an ultimate transportation network to serve the community needs.
Planning for Ultimate Growth
To maintain the quality of life enjoyed by the citizens’ of Round Rock, extensive future planning for the City’s transportation infrastructure is essential. An adequate transportation network is considered by many as the backbone to organized growth in any community. The total development of land within the present city limits, as well as, the ETJ at a certain time in the future is a reasonable conclusion from studying the development of communities that are similar to Round Rock. By planning for the ultimate growth of the city, the Transportation Master Plan establishes the ultimate roadway network and protects adequate rights-of-way to meet future transportation needs. The plan also provides property owners with a tool to minimize conflicts during development.
Land Use and Demographic Information
The City’s adopted existing and future land use plan was used as the basis for forecasting future demographic information needed for the Transportation Master Plan. Adjustments were made to the city’s land use plan in response to newly approved or anticipated development projects. Based on future land use, population and employment forecasts were made for the ultimate growth scenario, as well as, the years 2007 and 2017. The forecasted totals were then disaggregated to Traffic Analysis Zones (TAZs). These zones were used in the travel demand modeling process.
Traffic Demand Modeling
Using the population and employment data, computer models were used to forecast future travel on a transportation network between the various TAZs in the study area. The model generated traffic volumes for existing, as well as, forecasted trips. By studying the traffic volumes and the capacity of the roadways, the level of congestion was determined. A volume to capacity (V/C) ratio greater than one (1) normally reflected a need for roadway improvement. The modeling process was used as a tool to determine needed major transportation improvements. However, some recommended improvements were based on professional judgment.
During development of the Transportation Master Plan, consideration was given to Neighborhood and Community Resources, Water Quality, Air Quality, Historical Meteorology, Hazardous Materials, Threatened and Endangered Species, Natural Areas and Ecosystems, Parklands, Wetlands, Floodplains and Historic and Cultural Resources. Identifying environmentally-sensitive areas early during the planning process reduces the risk of cost overruns, schedule delays and design complexity.
In 1997, the Citizens of Round Rock authorized the adoption of a ½ cent sales and use tax dedicated to roadway improvements. In 2001, the City of Round Rock voters approved General Obligation Bonds including authorization of $37.1 million for streets, sidewalks, landscaping and traffic signal projects. The transportation project list was developed based on the City leveraging available funds to obtain additional funding from state, county and private sources, the City directly funding transportation system improvements and a future bond to be approved prior to 2020.
