Defining Future Mobility Conditions 4.1 Travel Demand Forecasting The City of Houston and the Houston-Galveston Area Council (H-GAC), through an inter-local agreement, conducted the travel demand forecasting within the study area. The Travel Demand Model (the model) is a useful tool for comparing alternative transportation scenarios.

The intent is to better understand the dynamics of a complex network of streets and to test what-if scenarios of different transportation solutions. The City, H-GAC, and the project team worked together to update the 2035 demographic forecasts. The updates included existing building permits, development trends, and traffic studies. Forecast Results - The Scenarios The study team created four initial scenarios for the Heights and Northside sub-areas. These scenarios were designed to test big ideas from local stakeholders, professional staff, and the consultant team. The different scenarios include: Scenario 1 (Base Build-Out) Scenario 2 (Couplets) Scenario 3 (Capacity Projects) Scenario 4 (High Frequency Transit) Scenario 5 (Recommendations) The scenarios were analyzed individually to allow for a comparison between different concepts. Ultimately, a combined scenario (Scenario 5) represents final recommendations the project team feels are realistic for implementation. The provided descriptions below demonstrate what modifications were made within each Scenario. To view final 2035 projection numbers associated with each Scenario, see Appendix E: Travel Demand Model Results. Scenario 1 (Base Build-Out) The Base Model scenario assumes the full development of all Major Thoroughfares and Major Collectors as identified in the 2013 MTFP. The effects of such recommendations on traffic volumes and congestion levels were evaluated in this scenario. The map of this scenario is found in Figure 4.1. Scenario 2 (Couplets) Heights’ area stakeholders requested that 19th/20th Street as well as Heights Boulevard/ Yale Street be tested as potential couplet pairings. Where excess capacity resulted, stakeholders requested a wider pedestrian realm and safer, buffered bike facilities. The map of this scenario is shown in Figure 4.2. Scenario 3 (Capacity Projects) Scenario 3 combines road expansion (as designated by the MTFP) and street reduction projects. The intent was to create a network that safely and reasonably supported a variety of mobility uses. This model is a more financially feasible option than the Base Model Scenario. The map of this scenario is found in Figure 4.3.

IV. Defining Future MobilityConditions

4.1 Travel Demand ForecastingThe City of Houston and the Houston-Galveston Area Council (H-GAC), through an

inter-local agreement, conducted the travel demand forecasting within the study area. The

Travel Demand Model (the model) is a useful tool for comparing alternative transportation

scenarios. The model assists in understanding the manner in which future population and

employment will cause traffic to grow. The intent is to better understand the dynamics

of a complex network of streets and to test what-if scenarios of different transportation

solutions.

The City, H-GAC, and the project team worked together to update the 2035 demographic

forecasts. The updates included existing building permits, development trends, and traffic

studies.

Forecast Results - The ScenariosThe study team created four initial scenarios for the Heights and Northside sub-areas.

These scenarios were designed to test big ideas from local stakeholders, professional

staff, and the consultant team. The different scenarios include:

• Scenario 1 (Base Build-Out)

• Scenario 2 (Couplets)

• Scenario 3 (Capacity Projects)

• Scenario 4 (High Frequency Transit)

• Scenario 5 (Recommendations)

The scenarios were analyzed individually to allow for a comparison between different

concepts. Ultimately, a combined scenario (Scenario 5) represents final recommendations

the project team feels are realistic for implementation. The provided descriptions below

demonstrate what modifications were made within each Scenario. To view final 2035

projection numbers associated with each Scenario, see Appendix E: Travel Demand Model

Results.

Scenario 1 (Base Build-Out)The Base Model scenario assumes the full development of all Major Thoroughfares and

Major Collectors as identified in the 2013 MTFP. The effects of such recommendations

on traffic volumes and congestion levels were evaluated in this scenario. The map of this

scenario is found in Figure 4.1.

Scenario 2 (Couplets)Heights’ area stakeholders requested that 19th/20th Street as well as Heights Boulevard/

Yale Street be tested as potential couplet pairings. Where excess capacity resulted,

stakeholders requested a wider pedestrian realm and safer, buffered bike facilities. The

map of this scenario is shown in Figure 4.2.

Scenario 3 (Capacity Projects)Scenario 3 combines road expansion (as designated by the MTFP) and street reduction

projects. The intent was to create a network that safely and reasonably supported a variety

of mobility uses. This model is a more financially feasible option than the Base Model

Scenario. The map of this scenario is found in Figure 4.3.

Page 2: IV. Defining Future Mobility Conditions projection numbers ......Scenario 3 combines road expansion (as designated by the MTFP) and street reduction projects. The intent was to create

36 Houston Mobility: Heights-Northside Study

Scenario 4 (High Frequency Transit)Scenario 4: This high frequency transit scenario included transit routes which factored

in public input, population growth, job growth, activity centers, and connectivity to other

destinations (such as downtown or the Galleria). The increase in service was modeled by

doubling the service frequency during the peak hours. Non-peak hour headways were also

increased slightly. Ultimately, however, METRO is responsible for the frequency and stop

locations of all City bus routes. The map of this scenario is found in Figure 4.4.

Scenario 5 (Recommendations)These four scenarios were analyzed separately and compared to the 2035 Base Model

as provided by H-GAC (with the new 2035 demographics previously discussed). Scenario

results were then taken to stakeholders for feedback. The provided input and the project

team’s analysis were combined to create Scenario 5. The result is a network of corridors

that acknowledges the need for the expansion as well as the reduction of certain corridors

(Scenario 3), increased High Frequency Transit Options (Scenario 4), and the completion

of key east-west and north-south corridors as depicted on the Major Thoroughfare and

Freeway Plan (Scenario 1). The map is found in Figure 4.5.
