Collin County led the Future Mobility Study in partnership with cities, adjacent counties, and other agencies such as the North Central Texas Council of Governments (NCTCOG) and the Texas Department of Transportation (TxDOT) to establish a regional approach to transportation planning. Since transportation needs do not stop at county lines, Dallas, Rockwall, and Hunt counties were included in the study.

The study focused on transportation needs in the eastern portion of Collin County. The study area was bound by I-30 on the south, SH 121 on the north, and the Collin County/Hunt County line on the east. The western boundary consisted of a combination of President George Bush Turnpike (PGBT), SH 78, FM 2551, SH 5, and Airport Boulevard.

Collin and adjoining counties have become attractive locations for new commercial and residential developments, which has made it difficult to identify land needed for future transportation improvements. Early planning and public involvement were crucial for maximizing mobility benefits, identifying and developing potential transportation options, evaluating and mitigating possible impacts, and preserving land for potential improvements.

Using data and feedback collected during the first phase, the second phase focused on identifying and analyzing specific improvements to support future transportation needs. The study team conducted an infrastructure assessment, modal analysis, traffic analysis, and route studies. Improvements were analyzed based on several factors, including engineering and traffic analysis, environmental impacts, cost, and stakeholder and public input.

Collin County, one of the fastest-growing counties in Texas, is projected to continue experiencing high growth. While much of the study area is very rural today, those areas are expected to become more developed over the next 30 years and beyond. Most major roadways in the study area are two-lane roads, which are not anticipated to meet future demands. This study allowed counties and cities to shape their mobility future and plan for necessary improvements.

Opportunities were provided during the second phase of the study for the public to give feedback. This feedback was used to help identify and develop transportation improvements for the study area.

Yes, improving safety for all modes of transportation was a priority during this study. A preliminary crash analysis was conducted using TxDOT’s Crash Records Information System (CRIS). The study team analyzed five years of crash data from 2015-2019 to identify areas where crashes frequently occur and opportunities to enhance safety on roadways within the study area.

Yes, during the second phase of the study, future transportation technologies were considered where reliable, quantitative data was available. Scenarios were developed to demonstrate how different adoption levels of connected and autonomous vehicles could impact future roadway capacity.

Regional connectivity was a critical component. Transportation needs do not stop at county lines, so Dallas, Rockwall, and Hunt counties were included in the study. Input from the public, businesses, agencies, and local governments played an essential role in understanding travel patterns.

No, new toll roads were not being considered in the study area.

No, a new bridge across Lavon Lake was not being considered due to environmental constraints, including potential impacts to property owned by the US Army Corps of Engineers.

Yes, transit and other modes of transportation were considered as part of the study.

Yes, the study incorporated feedback and data collected from prior planning efforts, including the 2014 Collin County Mobility Plan and the first phase of the Collin County Future Mobility Study. Current planning efforts, such as the Collin County Outer Loop, and the TxDOT US 380 projects, were also taken into consideration.

Population data and projections from sources such as the 2020 Census, NCTCOG, the Texas Demographic Center, and the Texas Water Development Board were considered. All sources indicated continued rapid population growth in Collin County.

A preliminary analysis of environmental data was conducted during the first phase of the study to identify land use, utility corridors, parks, conservation areas, and natural features. Constraints included Lavon Lake, Lake Ray Hubbard, other smaller lakes, Soil Conservation Site Reservoirs, US Army Corps of Engineers land, and oil and gas pipelines. The second phase of the study included further environmental studies.

The O&D Traffic Study looked at trips with vehicles traveling along SH 78, which is the only existing major north-south roadway and the roadway most frequently utilized by drivers within the study area. Data was also collected along SH 121 to understand travel patterns into and out of the study area along the north limits of the study area. While the study periods included pre- and mid-Covid, subsequent studies could also include data for post-Covid periods.
