Executive Summary

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

Before and After crash results comparisons on safety projects have consistently shown performance 

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

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

Spot improvement project selection, particularly with regard to intersection safety, has been more driven by 

HSM methodology this year, with the deployment of a custom GIS intersection network screening process 

which computes excess crashes with EB adjustment for all intersections on public highways in Maine 

regardless of jurisdiction. We continue to identify High Crash Locations each year as an additional 

consideration in prioritizing our spot improvement project candidates.

We continue to work on collecting the necessary MIRE data elements such as horizontal curvature to expand 

our network screening capabilities to include roadway segment geometry in addition to measured crash 

experience. To date we have leveraged our ARAN 9000 pavement condition data collection vehicle’s data 

streams to extract horizontal curves and cross slopes on one side of all MaineDOT Highway Corridor Priority 1-

4 roadways in the state highway and state aid systems. We are currently working towards obtaining cross 

slope information for the other lane by driving these roadways in the opposite direction as time and weather 

allows. We are currently developing custom GIS road segment screening tools that will assess the safety our 

highway network using excess crashes with EB adjustment in accordance with the HSM. 

In addition to spot improvements projects, Maine has used lane departure crash data to systemically evaluate 

our highway network for potential center line rumble strip locations as well as median cable barrier locations 

and has funded safety projects for both countermeasures. Due to continuing noise concerns expressed by 

residents, Maine's rumble strip program consisted entirely of sinusoidal style installations starting in 2018 and 

continuing in 2019. We have also conducted a systemic crash data study to identify horizontal curves that 

could benefit from the installation of edge line rumble strips to mitigate went-off-road crashes on these curves. 

The first installations of these curve enhancements will occur in the 2020 statewide rumble strip contract. 

Pedestrian Safety emphasis has a solidified strategy that continues in 2019 where targeted outreach to 

communities is underway which includes safety reviews of locations where public expressed priority needs. 

Program is multi-agency involved and emphasis includes improved pedestrian visibility at night with 

sponsorship of materials from 3M/Scotchlite. 

MaineDOT recently-created new Office of Safety consisting of a highway safety engineering section and a 

crash records section is now in place and staffed. The Office of Safety provides a single unit within the 

Department with the resources needed to perform data-driven safety analysis and coordinate safety candidate 

identification and evaluation efforts. The HSIP program is managed within the Office of Safety. 

While Maine’s overall crash rates have increased steadily since 2012, fatalities have varied quite widely from a 

recent high of 172 in 2017 to a recent low of 137 in 2018. In 2019, Maine's fatality count rose to 157 which is in 

the vicinity of recent 5-year averages. Serious injury counts and rates have continued to decrease steadily 

despite the increase in overall crashes statewide. 

2020 Safety Performance Targets were successfully coordinated internally, with Maine's Highway Safety Office 

(Bureau of Highway Safety) and MPO partners. The 2021 Statewide performance targets have also been 

developed. The 2020 Safety Performance Targets previously established did not account for the significant

drop in VMT we have experienced in 2020 due to the Covid-19 pandemic restrictions on interstate travel, 

increased teleworking, and other social distancing measures. Despite an approximately 20% decrease in VMT, 
2020 Maine Highway Safety Improvement Program

Page 5 of 59

we have not seen a corresponding decrease in the total fatalities and serious injuries. For Maine, this will most 

likely impact our 2020 fatality and serious injury rate targets which are expected to be much higher than 

originally predicted.

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 Reporting Guidance dated 

December 29, 2016 and consists of five sections: program structure, progress in implementing highway safety 

improvement projects, progress in achieving safety outcomes and performance targets, effectiveness of the 

improvements and compliance assessment. 

Program Structure

Program Administration 

Describe the general structure of the HSIP in the State. 

MaineDOT's HSIP program is managed by the Office of Safety which is led by a director level position that 

reports directly to the Chief Engineer. The Office of Safety consists of a highway safety engineering section, 

crash records section, and ADA Coordinator providing a single unit within the Department with the resources 

needed to perform data-driven safety analysis and coordinate safety candidate identification and evaluation 

efforts. 

In addition to identification of safety candidates through data driven analysis and network screening, the Office 

of Safety coordinates regularly with a wide variety of resources within MaineDOT including Regional 

Operations, Local Roads, our Active Transportation Planner, Traffic Engineering, and Regional Planners to 

identify additional areas of concern and potential safety and spot improvement candidates and to ensure that 

HSIP funding is being used for projects that support the initiatives and strategies identified in Maine’s Strategic 

Highway Safety Plan. 

The Department's Safety/Mobility Committee was created within MaineDOT and is comprised of a cross 

representation of MaineDOT functional areas that meets quarterly to review and coordinate work on potential 

safety and mobility projects, and to provide input on prioritization of HSIP projects for inclusion in the work 

plan. This committee is co-chaired by the Safety Office Director and the State Traffic Engineer. 

Where is HSIP staff located within the State DOT? 

 Other-Office of Safety

The Director of the Office of Safety reports directly to the Chief Engineer at MaineDOT. 

How are HSIP funds allocated in a State? 

• SHSP Emphasis Area Data 

• Other-Use Benefit Cost Criteria 

Describe how local and tribal roads are addressed as part of HSIP. 

Local roads are included with the state-wide project candidates. Maine captures crash and roadway data for all 

public roads and can evaluate all locations within the state based on similar crash and benefit/cost 

performance comparisons. Local safety project requests based on crash concerns are reviewed and evaluated 

as part of the candidate screening process using our network safety screening tools and methods. 
2020 Maine Highway Safety Improvement Program

Page 7 of 59

Maine has an on-line public crash data query tool available to them to help with local analysis - and 

MPOs/RPOs have utilized this tool and praise its capabilities. The Office of Safety is also available to provide 

data and technical assistance to MPOs and municipalities that would like help evaluating their safety areas of 

concern. 

Identify which internal partners (e.g., State departments of transportation (DOTs) 

Bureaus, Divisions) are involved with HSIP planning. 

• Design 

• Districts/Regions 

• Maintenance 

• Planning 

• Traffic Engineering/Safety 

Describe coordination with internal partners. 

Though the Office of Safety is the primary unit responsible for the development of HSIP project candidates, we 

coordinate with other units throughout the organization daily. Candidates generated from data-driven safety 

analysis or identified through other means are field reviewed through road safety audits or assessments that 

generally involve our region traffic engineers, regional planners, and active transportation planner. We also 

include other subject matter experts throughout the Department as warranted based on the type of safety 

issues we are investigating. Other systemic and spot improvement HSIP candidates are generated by our 

Transportation Analysis Unit in the Bureau of Planning and Traffic Engineering Group in the Bureau of 

Maintenance and Operations. Appropriate countermeasures are evaluated by the Office of Safety for each 

candidate using the Highway Safety Manual and checked to make sure the proposed candidate is an HSIP 

eligible activity in support of the Strategic Highway Safety Plan. This results in a vetted list of projects 

recommended for funding ranked in order of safety benefit/cost. 

In our experience, safety and mobility concerns are most often inextricably linked and MaineDOT strives to 

consider both throughout the project evaluation process. To that end, the Department formed a new 

Safety/Mobility Committee charged with functioning as a formal vehicle for communication and coordination of 

all work being performed in both areas. The Safety/Mobility Committee is co-chaired by the Director of the 

Office of Safety, and State Traffic Engineer and permanent members of this committee come from the 

following units within the Department: 

• Office of Safety (Engineering) 

• Office of Safety (Crash Records) 

• M&O (Traffic Engineering) 

• M&O (Region Traffic Engineer) 

• M&O (ITS Manager) 

• Planning (Regional Planner) 

• Planning (Active Transportation Planner) 

• Planning (Transportation Analysis) 

• Project Development (Multimodal Program Director) 

• FHWA Maine Division (Safety & Operations Engineer) 

The Safety/Mobility committee generates a prioritized list of projects recommended for funding to the 

Department’s Core Executive Team for final approval and inclusion in the work plan.

Identify which external partners are involved with HSIP planning. 

• FHWA 
2020 Maine Highway Safety Improvement Program

Page 8 of 59

• Governors Highway Safety Office 

• Law Enforcement Agency 

• Local Government Agency 

• Local Technical Assistance Program 

• Regional Planning Organizations (e.g. MPOs, RPOs, COGs) 

Describe coordination with external partners. 

The MaineDOT Office of Safety has continuing communications and good relationships with all State, local and 

Federal partners. In addition to standard state partners such as the Bureau of Highway Safety, we also 

coordinate with Bureau of Motor Vehicles and DHS for alcohol/drug-related issues. In addition, we regularly 

work with AAA, Maine Motor Transport Association, Maine Turnpike, Bicycle Coalition of Maine, United Bikers 

of Maine (motorcycles) and others. We look for input from all and communicate out to them when needed. One 

means of communicating and coordinating with these external partners is through the Maine Transportation 

Safety Coalition (MTSC) which meets quarterly for the purpose of coordination. 

Our coordination efforts with our MPO/RPO partners occurs on an ongoing basis as well in addition to the 

performance target setting activities required each year. We try to include these partners in our road safety 

audit/assessment efforts and obtain their assistance in reviewing High Crash Locations within their respective 

areas for further investigation by the Office of Safety. These partners are also included in our annual regional 

"synergy" meetings as part of the work plan development process to coordinate all project work including 

safety work. 

Program Methodology 

Does the State have an HSIP manual or similar that clearly describes HSIP planning, 

implementation and evaluation processes?

No

MaineDOT has an HSIP selection process document which details that specific portion of our HSIP processes, 

but we are currently in the process of expanding and updating our documentation to reflect recent changes to 

organizational and business process changes within the Department, specifically the creation of the Office of 

Safety and the Safety/Mobility Committee.

Does the State HSIP consider connected vehicles and ITS technologies? 

Yes 

Describe how the State HSIP considers connected vehicles and ITS technologies. 

MaineDOT continues to expand the use of ITS technologies and has assigned an ITS manager position within 

the Traffic Engineering section in the Bureau of Maintenance and Operations. The Department is in the 

process of creating our Transportation Management Center (TMC) and evaluating the deployment of additional 

technologies. The ITS Manager has a permanent/formal seat on the Department's newly-formed 

Safety/Mobility Committee, and the Director of the Office of Safety participates on the ITS Steering Committee. 

Does the State use the Highway Safety Manual to support HSIP efforts? 

Yes 
2020 Maine Highway Safety Improvement Program

Page 28 of 59

Please describe how the State uses the HSM to support HSIP efforts.

MaineDOT has created and deployed a web-based GIS application to perform network safety screening of 

intersection assets in accordance with the HSM. Specifically, we have chosen to screen using excess 

expected average crash frequency with EB adjustment as our methodology. We have extended this method 

further by computing excess crash costs to provide weight and focus to those facilities that are experiencing 

the most severe injuries and fatalities in our efforts to lessen the number and severity of these events. We are 

continuing to acquire the necessary MIRE data elements to perform similar screening on roadway segments 

but that is a work in progress. The Department also uses HSM methods to perform alternative countermeasure 

analysis for individual locations and and prioritization of projects recommended for funding.

None. MaineDOT Safety Office continues to work with internal and external partners to coordinate and 

integrate safety and seek the best opportunities to cost-effectively improve traffic safety. This process 

continues to be enhanced over time.

Describe any other aspects of the State’s progress in implementing HSIP projects on 

which the State would like to elaborate. 

2019 construction costs in Maine were much higher than expected for most all types of projects, not just safety 

projects. This has made it necessary to adjust our 3-year work plan by adjusting project estimates and 

adjusting schedules of some projects to stay within our fiscal restraints. 

Maine's leading crash exposure continues to be Lane Departure, experiencing 70% of state-wide fatalities in 

this category. Additional systemic safety opportunities are being evaluated to achieve a better funding mix that 

is reflective of SHSP priorities and to address these lane departure crashes. 2016 was the first year where we 

fielded calls on public noise-related concerns. MaineDOT’s 2018 and 2019 statewide rumble strip contracts 

specified that only sinusoidal center line rumble strips would be installed. This has substantially reduced the 

number of noise complaints we have received from the public. 

MaineDOT used data-driven analysis to screen for horizontal curves with significant crash experience and 

identified specific areas where edge line/center line rumble strips could be installed in the vicinity of the curve 

to decrease the likelihood of went-off-road crashes. These are programmed for installation in 2020.

Although not necessarily directly translating to HSIP funding, but certainly contributing to safety planning, there 

is continued dialogue with MPO's/RPO's on local safety needs and a cooperative approach on safety 

performance target setting. 

Pedestrian traffic fatalities are still a concern and a focused outreach program continues to be delivered 

throughout the state in 2019. This program includes public engagement and road safety audits and seeks to 

identify potential bike/pedestrian hazard mitigation that could be funded through HSIP or other fund sources. 

MaineDOT is also in the process of developing a pedestrian safety toolbox to identify appropriate safety 

countermeasures for locations with demonstrated vehicle/pedestrian crash exposure.

Number of Fatalities:158.0
2020 Maine Highway Safety Improvement Program

Page 46 of 59

Describe the basis for established target, including how it supports SHSP goals.

The following factors are likely to influence the ability of Maine to meet previous safety performance targets 

and need to be considered for future projections:• Maine’s annual VMT in 2020 is projected to be 

approximately 20% lower than originally estimated due to the social distancing and stay-home orders during 

the Covid-19 pandemic period which saw sharp decreases in VMT beginning in March and continuing through 

the middle of May. There is significant uncertainty surrounding the time it will take to “return to normal”, 

however, particularly with respect to tourist traffic as visitors cancel plans for vacationing in Maine in the 

summer of 2020. Based on Maine’s experience with recovery from the economic downturn of 2009, we will 

also set the projected 2021 VMT at 10% lower than 2019 actual VMT.• Maine’s economy and fuel prices have 

been and will continue to be affected by Covid-19 economic impacts on both businesses and citizens’ 

household finances. The tourism industry will be heavily impacted for the rest of 2020 and likely into early 

2021.• Multi-agency safety efforts will continue to be refined and focused on primary serious crash trends such 

as lane departure and pedestrians• Based on recruitment difficulties along with state and local budgetary 

constraints, law enforcement agencies will continue to experience staffing challenges, reducing the effective 

crash-reducing impact that their on-road presence has.• Impaired driving is a growing concern both due to 

legalization of marijuana and increased illicit drug usage. That growing impairment problems translates to 

serious crash exposures.• Maine Fatality data has varied widely during the 2019 Benchmark Performance 

(2015-2019) period ranging from 139 in 2018 to 172 in 2017. The 5-year average was 156.4 through the

period. Despite the lower VMT experienced this year during the Covid-19 stay-at-home period, Maine's 5-year 

fatality rate continues to trend slightly upward for the period with 2020 fatal numbers as of April 30, 2020 being 

near Maine’s 2019 fatal numbers at the same point in time. • MaineDOT suggests setting the 2021 fatalities 

target assuming a slight decrease from the 2020 target, but an increase in 2021 fatal rate target because this 

metric will be impacted by the expected 20% reduction in traffic in 2020 and 10% reduction in traffic in 2021.

Number of Serious Injuries:725.0

Describe the basis for established target, including how it supports SHSP goals.

• Serious Injuries (A) is one of Maine’s Safety Performance Areas that continues to show steady improvement 

over the years, but it too, has had erratic performance in the past. • Unlike 2020 fatalities, Maine has seen a 

slight reduction in the number of serious injuries during the Covid-19 pandemic measures. Uncertainty 

remains, however, as to the remainder of 2020 as motorists once again take to the state’s highways on a more 

frequent basis.• Recommended 2021 target is about equal with the 2019 Benchmark Performance (2015-

2019) for this measure. As with fatal rates, we also are anticipating a slightly higher rate of serious injuries due 

to lower project VMT for 2020 and 2021.

Fatality Rate:1.120

Describe the basis for established target, including how it supports SHSP goals.

The following factors are likely to influence the ability of Maine to meet previous safety performance targets 

and need to be considered for future projections:• Maine’s annual VMT in 2020 is projected to be

• Serious Injuries (A) is one of Maine’s Safety Performance Areas that continues to show steady improvement 

over the years, but it too, has had erratic performance in the past. • Unlike 2020 fatalities, Maine has seen a

2019) for this measure. As with fatal rates, we also are anticipating a slightly higher rate of serious injuries due 

to lower project VMT for 2020 and 2021.

Total Number of Non-Motorized Fatalities and Serious Injuries:89.0

Describe the basis for established target, including how it supports SHSP goals.

• As with statewide crash fatalities, this data has varied widely from year to year through the benchmark 

performance period, mainly due to the disparity observed from 2017 to 2018. Trends in 2020 indicate a slight 

move downward from our recent low in 2018 towards an average year from a non-motorized K&A perspective. 

• The 5-year Average for the 2015-2019 Benchmark Period was 86.6. It is hoped that our continued focused 

pedestrian outreach in 21 communities in Maine through STEP and HeadsUp programs will bring down our 

bike/ped fatality numbers and recommend setting a slightly lower target for 2021.

Describe efforts to coordinate with other stakeholders (e.g. MPOs, SHSO) to establish 

safety performance targets. 

Maine Bureau of Highway Safety and MaineDOT reviewed last year's targets and worked collaboratively to 

arrive at agreed upon goals and to make sure they are in context with the latest influencing factors such as the 

reduced VMT due to the Covid-19 pandemic.

MaineDOT has earlier discussed its target setting philosophy with MPOs and how it would translate to MPO 

performance targets. The Department prepares suggested performance targets for each MPO as a starting 

point for discussion and provides the necessary data for them to evaluate their own past performance and to 

either accept MaineDOT's recommendation or to come up with their own.

Does the State want to report additional optional targets? 

No

None

Describe progress toward meeting the State’s 2019 Safety Performance Targets (based 

on data available at the time of reporting). For each target, include a discussion of any 

reasons for differences in the actual outcomes and targets.

PERFORMANCE MEASURES TARGETS ACTUALS

Number of Fatalities 165.0 156.2

Number of Serious Injuries 737.6 720.4

Fatality Rate 1.100 1.042

Serious Injury Rate 4.900 4.798

Non-Motorized Fatalities and 

Serious Injuries

91.0 86.8

All five of Maine’s 2019 Safety Performance Targets were met. This was in large part to the unusual drop in 

pedestrian fatalities in 2018 which brought the overall and 5-year average benchmark fatal numbers and rate 

down and will likely continue to do so as long as 2018 is part of our 5-year average fatality computations. 

Maine’s serious injury numbers and rates have been steadily decreasing since 2012 despite increased 

statewide vehicle miles traveled and continued to do so for this reporting period. Both factors contributed to our 

meeting the number of non-motorized fatalities and serious injury performance target as well. Our 2019 fatality 

count overall was closer to the 2010-2016 average counts but we continued to see a steady decrease in 

serious injury crashes. 

Our early 2020 crash reports would indicate we’re likely to see average fatality and serious injury counts for 

2020, but much higher crash rates due to the unanticipated drop in statewide VMT due to COVID-19 this year.

Evaluation

Program Effectiveness 

How does the State measure effectiveness of the HSIP? 

• Benefit/Cost Ratio 

• Change in fatalities and serious injuries 

Infrastructure projects are evaluated each year with results included with HSIP (before/after injuries and B/C). 

Systemic improvements like rumble strips are periodically reviewed for collective performance where installed. 

Based on the measures of effectiveness selected previously, describe the results of 

the State's program level evaluations. 

Maine's fatality rate increased from 2014 through 2017, but in 2018 we experienced a notable decrease, 

mainly due to a sharp decrease in the numbers of pedestrian fatalities reported. In 2019, that number 

increased again returning to a value closer to the previous 5-year average. Our serious injury rate has been 

steadily decreasing since a peak in 2012. This downward trend continued in 2019. 

Our overall benefit-cost performance on mitigation efforts has been good. Systemic installations such as center 

line rumble strips have continued to prove very effective at a relatively low cost. We plan to expand this 

program as we continue to explore new systemic safety programs that have proven to be successful in other 

states. 

We recently completed a statewide assessment of our center line rumble strip program for those segments 

with three years of before/after crash data available which shows an average reduction in fatalities and serious 

injuries of 62.9% and 48.1% respectively where these are installed. 

MaineDOT is also in the preliminary stages of a study quantifying the benefits of converting rural two-way stop 

controlled intersection to all-stop controlled intersections. Preliminary data shows a significant reduction in both 

the number and severity of crashes at these facilities after conversion. Overall, we are observing a 70% 

reduction in crash costs with this countermeasure. 

What other indicators of success does the State use to demonstrate effectiveness and 

success of the Highway Safety Improvement Program? 

• # miles improved by HSIP 

• Increased awareness of safety and data-driven process 

• Increased focus on local road safety 

• More systemic programs 

• Policy change 

• Other-Pedestrian Strategic Focus Outcomes 

Describe significant program changes that have occurred since the last reporting 

period. 

MaineDOT experienced a significant and unexpected increase in construction costs for all projects in 2019, 

including HSIP-funded improvements. This increase required a broad adjustment of estimates for previouslyprogrammed projects that will undoubtedly affect our anticipated fatality and serious injury improvements in the 

future as some of these projects had to be moved to future years to match available funding.

Describe any other aspects of HSIP effectiveness on which the State would like to elaborate.

Our rumble strip program continues to be an effective mitigation effort for head-on lane departure crashes and their associated injuries. Switching to sinusoidal rumble strips exclusively beginning in 2018 has also led to improved public 

acceptance of their presence on the roadway. We have also begun a pilot installation of edge line rumble strips on select sharp horizontal curves with a history of lane departure crashes in hopes of mitigating fatalities and serious injuries 

at those locations.

Describe actions the State will take moving forward to meet the requirement to have complete access to the MIRE fundamental data elements on all public roads by September 30, 2026. 

MaineDOT continues to explore and prototype methods for collecting the remaining elements. Our ongoing effort involving leveraging the GPS data stream from our ARAN 9000 pavement condition data collection vehicle to extract 

horizontal curvature of state highways has proven to be a very effective means to obtain this data. We have processed this data for all Highway Corridor Priority 4 and higher in one direction and are now driving those same roadways in 

the opposite direction as time allows to obtain superelevation data for the other lane on horizontal curves. This new collection effort is being completed at the end of the data collection season after our required regular network pavement 

data collection is complete. We currently have no plans to perform this collection on local roads using this method but will explore options to obtain this data by some other means in the future. 

MaineDOT's Office of Safety will hold internal meetings with our Results and Information Office to discuss the process and resources required and timeline expected to complete the MIRE FDEs by the deadline.

Glossary

5 year rolling average: means the average of five individuals, 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.

Systematic: refers to an approach where an agency deploys countermeasures at all locations across 

a system.

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.
