High Occupancy Vehicle/Park & Ride Study
Sponsor: COMPASS and Valley Regional Transit
Status: June 2011

Study will determine how a high occupancy vehicle transportation system, including park-and-ride facilities, may benefit mobility in the Treasure Valley. And development of a comprehensive evaluation of a high occupancy vehicle and/or park-and-ride system plan.

 

High Volume Intersection Study
Sponsor: COMPASS
Status: Completed April 2008

This study identified optimal designs for nine intersections with high volumes of forecasted traffic in Ada County. The top intersections were determined using the transportation demand model and input from the Idaho Transportation Department, the Ada County Highway District, and local jurisdictions, with input from the consultant. The consultant researched innovative intersection layouts, and other guidelines that will provide guidance on appropriate intersection design and other standards for surrounding areas.

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
Sponsor: Idaho Transportation Department
Status: Completed 2009

The GARVEE-funded study is a transportation plan for the final 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 Federal Highway Administration issued a finding of No Significant Impact in April 2009. The environmental document included a long-term improvement plan, conceptual plan, preferred alternatives, and right-of-way requirements.

Questions should be directed to the Idaho Transportation Department at 334-8300.

 

I-84, Orchard to Isaacs Canyon Corridor
Sponsor: Idaho Transportation Department
Status: Completed 2009

The GARVEE-funded project covers a nine-mile corridor extends from the Orchard Interchange to the Gowen Interchange. The project includes 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. Construction is currently underway, and is scheduled for completion the summer of 2011. Work on the corridor is divided into four projects: Cole Interchange to Broadway IC Soundwalls, Cole Interchange to Broadway Interchange, Orchard Street Interchange, and Broadway Interchange to Eisenman Interchange.

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.
