Communities in Motion (CIM): |
The regional long-range transportation plan for Ada and Canyon Counties. The plan serves as the defining vision for the Treasure Valley’s transportation systems and services and indicates the transportation improvements scheduled for funding over the next 20 years. CIM was originally adopted in 2006 and updated in 2010, 2014, 2018, and 2022. “Communities in Motion” is often accompanied by a year (e.g., Communities in Motion 2050), which indicates the horizon year of that specific Communities in Motion plan. |
Communities in Motion 2050 (CIM 2050) Vision |
The “preferred growth scenario” for Communities in Motion 2050. The Communities in Motion 2050 Vision illustrates the amount, type, and location of growth forecasted to the year 2050 for Ada and Canyon Counties, ID. Created using input from local stakeholders, including the public, the CIM 2050 Vision guides development of the long-range transportation plan, Communities in Motion 2050. Both the Communities in Motion 2050 plan and Vision support safety, convenience, economic vitality, and quality of life for all residents. |

Complete Network |
An approach to designing a transportation system to ensure that the entire system serves all users — pedestrians, bicyclists, transit users, and motor vehicle drivers, as well as freight needs — based on the land use contexts and role in the overall system. The concept of a “complete network” differs from a “complete street” in that it does not strive for all roadways to serve all needs for all people, but rather considers the context of land uses, roadway users, roadway typologies, and parallel routes, combined, to provide a safe, reliable, and efficient transportation system for all. |
Complete Street |
A concept in transportation design that strives to ensure roadways serve all users. |
Congestion Management System (CMS) |
A systematic process for managing traffic congestion. A CMS provides information on transportation system performance and finds productive ways to manage the growth of congestion and enhance the mobility of people and goods, to levels that meet state and local needs. |
