State of Alaska Project No. CFHWY00289

Welcome

The Alaska Department of Transportation and Public Facilities (DOT&PF), in cooperation with the Federal Highway Administration (FHWA), is preparing the Glenn Highway Integrated Corridor Management (ICM) Study. The study is funded through the Anchorage Metropolitan Area Transportation Solutions (AMATS).

Purpose

The ICM Study aims to identify methods to improve the efficiency of the movement of people and goods along the corridor, specifically as it relates to non-recurring congestion. These measures are intended to increase reliability and predictability of travel through the corridor.

What is recurring and non-recurring congestion?

Recurring congestion refers to delay that is experienced on a roadway on a daily basis simply because there are so many people using the roadway.

Non-recurring congestion refers to delay that is caused by other factors, such as: a lane closure due to a crash or construction; special events that cause more traffic than usual; or weather events.

Location

The Glenn Highway from Airport Heights Drive to the Knik River bridge. The Knik River bridge is the boundary between Anchorage and the Matanuska-Susitna Borough. Due to the funding source, this project’s work will be performed within the Municipality of Anchorage.

Process

The team will identify the factors that relate to the reason for non-recurring delays, including incident response times and clearing times. Information will be collected by reviewing previously completed reports, speaking with key agencies, organizations, and the public.

The ICM will examine alternative ways to route traffic for lane shutdown conditions including existing routes as well as the potential to connect and complete frontage roads. Alternative modes of transportation, including commuter rail service as a possible option, will be considered.

We will evaluate the performance of recently implemented measures to reduce delay, the anticipated performance of new measures identified, as well as how feasible they are to implement. The ICM will look at incorporating, refining, and integrating current practices. Evaluation will take into account delay for all user groups as well as their safety including pedestrians, cyclists, transit users, drivers, truckers, and responders.

End Product

A report will be produced with recommended measures for future implementation. The draft report can be found here.
