Transportation Master Plan​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​

What is the Thornton Transportation Plan?

The current Transportation Master Plan for the City of Thornton was adopted by City Council Resolution on September 8, 2009 with the Colorado Department of Transportation's I-25 and  Highway 7 Planning, Environmental and Linkages studies incorporated by City Council Resolution on March 29, 2016. The plan is the City’s long-range plan for travel and mobility, guiding future development of transportation-related infrastructure. This plan includes information about existing transportation conditions, challenges, and opportunities. It also provides an evaluation of future motorized and non-motorized needs based on the future land use projections and overall vision for the city. For example, the plan recommends what roads should be widened or improved, what new roads should be built, where bike lanes should be provided on City roads, and how the new North Metro Rail line can be connected to the road, bus and trail system.

The Transportation Plan examines the city as a whole to view the broad range of issues that impact travel and mobility -- including land use, pedestrian, bicycle, and transit issues -- rather than merely level of service, traffic counts and future modeling projections.

Technical Questions

What is the CIP? The Capital Improvements Program or CIP is a timetable or schedule of all future capital improvements to be carried out during a specific period, listed in order of priority, together with cost estimates and the anticipated means and sources of financing each project.

The City maintains a five-year plan, which is updated annually. Projects include improvements to transportation, water, storm and sanitary sewer systems. 

What are TAZ’s? TAZ’s or Traffic Analysis Zones are distinct areas of the city identified on a map with the associated population and job numbers for those areas. The population/job numbers can be for today or for future time periods, for instance for 2035. This information is critical for the TRANSCAD model. 

What is TRANSCAD? TRANSCAD is computer modeling that, after the necessary data has been input, provides a modeler the ability to produce maps showing current and projected traffic volumes. 
What is a PEL? PEL is an abbreviation for Planning, Environmental, and Linkages.  These studies are part of the environmental process that identifies the number of lanes, environmental issues, right-of-way needs, and other transportation infrastructure needs and reviews alternatives and recommends the preferred alternative.
