MAG Highway Safety Improvement Program

The Highway Safety Improvement Program (HSIP) was introduced through SAFETEA-LU. It is focused on improving road safety. The Federal Highway Administration (FHWA) division offices located in each state manage program implementation, review states’ annual highway improvement program reports, and provides oversight of program funding.

The amount of HSIP funds allocated to each state is based on three factors with each carrying equal weight: (1) the number of persons killed in crashes; (2) lane miles of roads; (3) vehicle-miles traveled. The Arizona Department of Transportation (ADOT) decided to sub-allocate 20 percent of all HSIP funds that Arizona receives each fiscal year (i.e. 20% of approximately $29 million) to all Metropolitan Planning Organizations (MPOs) and Councils of Governments (COGs) in the state based on a formula. Starting in fiscal year (FY) 2010, MAG received $1 million in HSIP funds each year for programming projects that would meet the FHWA and ADOT approval. Another 10 percent of HSIP funds was allocated as flexible funds for non-infrastructure safety programs identified in the state's Strategic Highway Safety Plan (SHSP). They are administered by ADOT. The largest portion of HSIP funds, accounting for 70 percent, is for safety improvements on public roads. Starting in 2016, the ADOT program guidance provides for a statewide competition for safety improvement projects utilizing HSIP funds.

Most of the state's road safety problems exist in Maricopa County. Crash records for the last 10 years indicate that nearly 40 percent of all road deaths and 66 percent of crashes with serious injuries in Arizona occur Maricopa County roads. Within Maricopa County, nearly 80 percent of all road deaths and serious injuries occur on the arterial and local road system with only 20 percent on the freeway/expressway system.

MAG FY 2023 and 2024 HSIP Call for Projects

On January 7, 2019, ADOT requested MAG and other COGs and MPOs to issue and coordinate a call for projects for programming new projects in FY2023 and 2024. MAG is coordinating this call for projects with ADOT, and will recommend a list of projects for the available HSIP funds. Project applications submitted by the Monday April 15, 2019 deadline can be viewed below along with those submitted in previous cycles. Revised HSIP guidelines and a new HSIP project application form provided by ADOT is available at the links provided (see below).
