High Volume Intersection Study
Sponsor: COMPASS
Status: Completed April 2008
This study provides optimal designs for intersections with high volumes of forecasted traffic in Ada County. The top intersections were selected using the transportation demand model and input from the Idaho Transportation Department, Ada County Highway District, and local jurisdictions. A consultant team researched and provided intersection layouts and other guidelines for land development, access management standards, etc.

Household Travel Survey
Sponsor: COMPASS
Status: To begin in 2011
This study will collect household travel characteristics to update and expand the COMPASS travel demand model. Data will be collected in the Communities in Motion six-county region. This study will take part in two phases during two consecutive years.
I-84, Karcher Interchange to Five Mile Road, Ada and Canyon Counties
Sponsor: Idaho Transportation Department
Status: Ongoing, expected completion 2010
This study is a transportation plan for the ultimate build-out of the interstate for the area between the junctions of I-84 and SH 44 and I-84 and Five Mile Road. The study will obtain approval from the Federal Highway Administration on expected access points, a footprint of anticipated interchanges and roadway widening projects, the order of construction (priority), and various ways to finance the projects. This study will also include preliminary design and environmental elements so Right-of-Way can be preserved.
I-84, Orchard to Isaacs Canyon Corridor
Sponsor: Idaho Transportation Department
Status: Ongoing in 2008
The original scope of work for the project was to complete a Concept Report, preliminary engineering, environmental document, and a construction staging plan for the corridor of I-84, from the Orchard Interchange to the Gowen Interchange. The project included replacing the existing two lanes of concrete pavement, widening to meet needs through 2035, and replacing four interchanges. This project was expanded as part of the Connecting Idaho program to include I-84 between the Isaac's Canyon interchange to just west of the Orchard Interchange. The project is currently going through the environmental assessment stages. Preliminary and final design will begin once the environmental assessment stages have been completed.
Questions should be directed to the Idaho Transportation Department at 334-8300.
I-84, Ten Mile Interchange Access Study
Sponsor: Idaho Transportation Department
Status: Complete, approved in August 2005
This project will develop an Access Report to determine the operational characteristics of the interchange and obtain Federal Highway Administration concurrence that an interchange will be allowed at this location. This project will also study possible funding scenarios. At this time there are no funds programmed for construction. Construction staging scenarios will also be studied.
Questions should be directed to the Idaho Transportation Department at 334-8300.
Idaho 55 Eagle Road Advanced Transportation Management System
Sponsors: Idaho Transportation Department and Ada County Highway District
Status:
Completed October 2005
Study will develop an advanced transportation management framework, conceptual design and implementation strategy, optimized signal timing plans, and a benefit-cost analysis of the deployment. The study area includes Eagle Road between Overland Road and SH 44. The mission of the project is to provide effective ITS (intelligent transportation system) services for the Eagle Road corridor that enhance the safety and mobility of people and goods, and the quality of the environment and communities. Updated traffic technology and signal systems are being designed to increase coordination between signals, and should be implemented in 2009.
Questions should be directed to the Idaho Transportation Department at 334-8300.
