Executive Summary

Maine has a data driven approach for HSIP project selection, assessing various aspects of crash 

performance. Before and After crash results comparsion have consistently shown performance 

improvement over the years. HSIP selection process is re-evaluated each year to see if there 

opportunities for enhancement and for improved alignment for the state's SHSP. 

Supplemental safety projects that are more systemic in nature, like centerline rumble strips and 

median cable barrier are also funded. Maine is looking to expand it's systemic approach to 

further impact lane departure crash reduction - Maine leading crash concern.

Introduction

The Highway Safety Improvement Program (HSIP) is a core Federal-aid program 

with the purpose of achieving a significant reduction in fatalities and serious 

injuries on all public roads. As per 23 U.S.C. 148(h) and 23 CFR 924.15, States are 

required to report annually on the progress being made to advance HSIP 

implementation and evaluation efforts. The format of this report is consistent 

with the HSIP MAP-21 Reporting Guidance dated February 13, 2013 and consists 

of four sections: program structure, progress in implementing HSIP projects, 

progress in achieving safety performance targets, and assessment of the 

effectiveness of the improvements.

Describe how local roads are addressed as part of Highway Safety Improvement Program.

Local roads are included with the state-wide project candidates. Maine does capture crash and 

roadway data for Local roads and so is able to evaluate all locations within the state based on 

similar crash performance comparisons. Local requests are also receieved based on crash 

concerns and are reviewed as part of the candidate screening process.

In terms of local road systemic improvements, MaineDOT's funding and approach are being 

evaluated for future funding periods.

Briefly describe coordination with internal partners. 

Executive, Planning (including local roads and bike/ped), Traffic Engineering, Project 

Development, all play a part in safety planning. MaineDOT continues to enhance its Work Plan 

approach to integrate safety into the planning process, looking to get safety in the planning 

thought process early on to consider not just stand-alone safety needs, but also opportunities 

that would complement upcoming paving and construction projects. Safety Office is able to 

review corridor project candidates in advance to identify safety needs that might align with 

other work.

A Highway Safety Group has recently been established that includes a wide operational 

representation and FHWA presence to look at overall safety needs, funding philosophy and 

systemic opportunities.

MaineDOT Regions have been very involved with Centerline Rumble Strip strategies, corridor 

reviews and project implementation.

Describe any other aspects of the Highway Safety Improvement Program methodology on which you 

would like to elaborate. 

Coordination between MaineDOT safety and other MaineDOT operating units continue to deepen, as 

we look to jointly define safety needs and issues coordinate best mitigation techniques, and then 

integrate in Work Plan - coordinating with construction and paving projects when appropriate.

Discuss impediments to obligating Highway Safety Improvement Program funds and plans to 

overcome this in the future.

No impediments seen. Safety Office continues to work with MaineDOT Exec., various 

MaineDOT operational areas and Regions to improve safety planning corrdination/integration.

Describe any other aspects of the general Highway Safety Improvement Program implementation 

progress on which you would like to elaborate.

Maine's leading crash exposure continues to be Lane Departure, experiencing 70% of statewide fatalities in this category. Head-on fatalities were up 50% in 2014 compared to recent 

prior years. Systemic opportunities are being evaluated to achieve a better funding balance that 

is reflective of SHSP priorities - 2015 is seeing an increase in installations on centerline rumble 

strips - 90 miles planned for this year, compared to the 60 miles currently existing on noninterstate road installations completed since 2006. Additional opportunities are anticipated for 

future planning years.

Although not directly translating to HSIP funding, there is increased dialogue with MPO's/RPO's 

and the bike/ ped community.

Describe any other aspects of the general highway safety trends on which you would like to elaborate.

Maine's fatality trends have been generally positive and continue to improve, with 2014 fatalities being 

the lowest in the past 70 years. Maine continues to agressively work with Police agencies to make sure 

there has been complete reporting submissions. We have identified limited departments that have had 

issues with successful electronic report exporting. Incapacitating injuries are not improving as much but 

have stabilized after hitting a recent high in 2012, and have been improving in the last two years.

Maine's lead crash concern continues to be lane departure. While overall numbers are trending down, 

Lane Departure still represents 70% of the state's fatalities. Head On fatalities were about about 50% as 

compared to recent prior years.

*Performance measure data is presented using a five-year rolling average.

Queried in Maine's Crash Reporting database all crashes resulting in fatality or serious injury when 

fatality or injury occurred to Crash Report Person Type: Driver, Driver Owner or Pedestrian over 65 years 

old. 

Using those crash ID's, summed all resulting crash serious injuries by year. Obtained fatal numbers 

through Maine's FARS analyst.

Developed rates based on Section 148: Older Drivers and Pedestrians Special Rule Interim Guidance;

76

Does the older driver special rule apply to your state? 

Yes

If yes, describe the approach to include respective strategies to address the increase in those rates in 

the State SHSP.

Main continuing activity is driven by the Maine's Mature Driver Safety working group that is looking to 

enhance public outreach to mature drivers, family members, clinicians and other support services to 

emphasize importance of driver assessments and provide guidance on appropriate driver interventions 

when demonstrated skills are diminishing. Mature Drivers is a focus area in Maine's current SHSP and 
2015 Maine Highway Safety Improvement Program

77

has been updated in the new 2014 SHSP edition. The Mature Driver Safety Group has met together with 

a media consultant to identify best strategies to meet the above objectives.

2015 Maine Highway Safety Improvement Program

79

Maine's SHSP had a major update in 2014 that meshed with strategies within HSP. It also added 

performance results and targets for both Fatalities and Incapacitating Injuries for each focus area in line 

with anticipated MAP-21 guidance.

As noted else where in this report, Maine is expanding installation of centerline rumble strips - with 90 

miles of new centerline RS being installed within the next couple of months.

Coordination with Planning (Paving and construction work), Regions, Traffic Engineering and other 

MaineDOT operational areas for safety planning continues to see process improvement. There is a 

renewed look at crash data to try to evaluate systemic funding opportunities.

Describe any other aspects of the overall Highway Safety Improvement Program effectiveness on 

which you would like to elaborate. 

A new SHSP was developed and released in late 2014, along with a crash data book. The SHSP 

aligns with Maine Bureau of Highway Safety's Highway Safety Plan and establishes performance 

targets matching what's being featured in MAP-21.

Maine has provided median cable barrier installations on all narrow (<50-60' wide) interstate 

medians. MaineDOT does plan to automate that feature in its road inventory to enable easier 

monitoring of performance in the future. No fatalities have occured on sections where median 

cable barrier has been installed, but incidental barrier/guardrail hits have increased. Maine 

experienced 4 interstate median crossover fatalities from 2005 to 2009, none since.

Centerline Rumble strips were added to three selected corridors in late 2013, two more are 

planned for later 2014 (which will bring Maine's total to 10 sections of non-interstate 

Centerline Rumble Strip installations). Ninety miles of rumble strips were installed in 2015, with 

more planned for 2016-17. One 2014 head-on fatality has occurred on corridors where 

installed, but overall performance has significantly improved. A systemic approach to 

determine the next wave of rumble strip installations is underway.

MaineDOT is employing more of a proactive systemic safety approach for future planning. With 

head on crash mitigation (rumble strips) well underway, the next area of attention will be Went 

Off Road crashes and then other areas will be added, like intersections.

Glossary

5 year rolling average means the average of five individual, consecutive annual points of data (e.g. 

annual fatality rate).

Emphasis area means a highway safety priority in a State’s SHSP, identified through a data-driven, 

collaborative process. 

Highway safety improvement project means strategies, activities and projects on a public road that are 

consistent with a State strategic highway safety plan and corrects or improves a hazardous road location 

or feature or addresses a highway safety problem. 

HMVMT means hundred million vehicle miles traveled.

Non-infrastructure projects are projects that do not result in construction. Examples of noninfrastructure projects include road safety audits, transportation safety planning activities, 

improvements in the collection and analysis of data, education and outreach, and enforcement 

activities.

Older driver special rule applies if traffic fatalities and serious injuries per capita for drivers and 

pedestrians over the age of 65 in a State increases during the most recent 2-year period for which data 

are available, as defined in the Older Driver and Pedestrian Special Rule Interim Guidance dated 

February 13, 2013. 

Performance measure means indicators that enable decision-makers and other stakeholders to monitor 

changes in system condition and performance against established visions, goals, and objectives.

Programmed funds mean those funds that have been programmed in the Statewide Transportation 

Improvement Program (STIP) to be expended on highway safety improvement projects.

Roadway Functional Classification means the process by which streets and highways are grouped into 

classes, or systems, according to the character of service they are intended to provide.

Strategic Highway Safety Plan (SHSP) means a comprehensive, multi-disciplinary plan, based on safety 

data developed by a State Department of Transportation in accordance with 23 U.S.C. 148. 

Systemic safety improvement means an improvement that is widely implemented based on high risk 

roadway features that are correlated with specific severe crash types. 

Transfer means, in accordance with provisions of 23 U.S.C. 126, a State may transfer from an 

apportionment under section 104(b) not to exceed 50 percent of the amount apportioned for the fiscal 

year to any other apportionment of the State under that section.
