The Regional Transit Center is adjacent to Research Triangle Park and is managed by GoTriangle. Research Triangle Park is located just on the fringe of Morrisville, spanning both Wake and Durham Counties. The research and technology park is approximately 7,000 acres and is home to more than 26000 businesses and nearly 50,000 employees. Sharrows are pavement markings used to denote that bicycles “share” the travel lane with motorized traffic. A staged, multiyear, statewide intermodal program of transportation projects which is consistent with the statewide transportation planning processes, Metropolitan Transportation Plans (MTP), Transportation Improvement Programs (TIP). The common name used for the trust fund or process established under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) to clean up hazardous waste sites across the U.S. A system of actions whose purpose is to alleviate traffic problems through improved management of vehicle trip demand. These actions, which are primarily directed at commuter travel, are structured to either reduce the dependence on and use of single-occupant vehicles, or to alter the timing of travel to other, less congested time periods. A facility with a functional purpose of moderate to low mobility and high access. The facility has no control of access, traffic signals, driveways with full movements, and a minimum of 2 travel lanes without a median. Connections are provided primarily at at-grade intersections. The Transportation Improvement Program identifies the transportation projects that the Capital Area MPO and NCDOT plan to complete over the next 10 years. The TIP is incorporated directly into North Carolina’s State Transportation Improvement Program (STIP). The Triangle Regional Model is a state of the practice travel demand model developed and maintained by the Travel Behavior Modeling Group and four stakeholder sponsors: NC Department of Transportation, Durham-Chapel Hill Carrboro Metropolitan Planning Organization, Capital Area Metropolitan Planning Organization, and GoTriangle. The Triangle Regional Model is used to plan transportation investments in the Triangle region of North Carolina. A Unified Development Ordinance is a local policy instrument that combines traditional zoning and subdivision regulations, along with other desired Town regulations, such as design guidelines, sign regulations, and stormwater management into one document.
