Use of Uniformed Police Officers on Federal-Aid Highway Construction Projects Executive Summary Presentation Prepared by Editor’s Ink Subcontractor to Henderson Assoc. June 8, 2000
Overview of Presentation • Background • Survey • Policies • Effectiveness • Summary • Recommendations
Background • TEA-21 required DOT to: “…conduct a study with States, State transportation departments, and law enforcement organizations, on the extent and effectiveness of use of uniformed police officers on Federal-aid highway construction projects.”
Background • Survey • Federal Register Notice • Federal Register Survey Questions • General Comments encouraged • AASHTO Survey • Analysis of Policies & Studies
State Transportation Agency Respondents Respondents
Law Enforcement Respondents Respondents
Survey Responses • The total number of survey respondents was 70. • Not all survey respondents answered all questions. • Therefore the number of respondents (N) is DIFFERENT for EACH QUESTION.
Size of Law EnforcementAgency • Only 25 Responses • Average = 1,123 • Range = 132 - 6,644 • Median = 3,388
Size of Jurisdiction • All > 100,000 population
Does Agency Have Policy? • Written policies generally provide for hiring off-duty police officers to work construction zones, although a few States use only on-duty officers • Funding from DOT, usually • Some “yes” responders said they had “unwritten” policies
Extent of Use of UPOs • Survey Data • Analysis of Policies Submitted
Circumstances Where UPOsMost Often Used • Nighttime operations • Lane or road closures • High speed/ Hi volume traffic
Only a Few Agencies Use UPOs in All Projects • Arizona (unwritten policy) • Rhode Island • City of Boston
How is Number of Officers Determined? • Responses vary widely • Job site factors • location • traffic volume/speed • nighttime operations • complaints, problems, or special operations • Available funding • Procedural factors • Manpower factors
Use of Off-Duty vs On-Duty UPOs (Based on Survey Data & Policies Submitted) Off Duty On Duty
92% of Respondents said UPOs used Marked Vehicles at Construction Projects Yes 92% No 4% Varies 4% No response
Officer Positioning & Gear • 11% of survey respondents said they require officers to be outside vehicle • 33% require high-visibility clothing
24% of Survey Respondents said their State Conducts a UPO Training Program
Who’s In Charge? • Who Developed the Policy? • Who Determines the Number of Officers? • Are UPOs included in the Planning Process?
Effectiveness of Policies • Survey Data--Mostly Opinion, but Indicates Positive Effects • Hard “Real World” Data is Scarce • Academic Research also Scarce, but Generally Positive
Effects of Policies: Academic Studies • Generally Positive Results • Document that UPO Presence Reduces Speed as much as or more than other traffic control methods • Some guidelines available
Effects of Policies: Academic Studies Transafety Paper, Noel, et al, 1987 Compared: 1. MUTCD flagging procedure 2. MUTCD flagging procedure w/ add’l flagger hand motions 3. marked police car w/ lights & radar 4. UPOs standing to control traffic
Effects of Policies: Academic Studies Noel et al found: “The law enforcement methods demonstrated a stronger speed reduction capability; particularly when lane closures result in two or more lanes open.”
Effects of Policies: Academic Studies Transportation Research Board, Richards, et al, 1985 Findings: Flagging & law enforcement were best methods. Best flagging methods reduced speeds an average of 19% Best Law enforcement methods reduced speeds by an average of 18%.
Has Your Agency Conducted Studies on use of UPOs in Work Zones?N = 58
Studies by States • A few states track # of citations, # of collisions, injuries, etc. Generally do not provide conclusive data on effectiveness • Some law enforcement agencies provided info on budget, # of officers assigned, etc.
General Comments Received • General comments were overwhelmingly supportive • AASHTO 1997 Policy Resolution supports use of Federal-aid funds for UPOs in work zones • 2 of 10 highway industry associations had methodology suggestions: • AHAS: encourages gathering more hard data • IIHS: recommends study of automated enforcement as supplement to UPOs
Summary Findings • Report documents widespread use, and support for, the use of UPOs in work zones. (extent) • Little hard data available on actual effects of policies. • Survey data show State policies and procedures vary widely.
Issues Summary • Policies vary Re: • Circumstances Where UPOs are Required • Number of Officers Required • Training, Procedures, & Supervision • Conflicting Missions (Traffic Control vs. Speed Enforcement)
States Served By FHWA Mobile Asphalt Laboratory 1993-2000 Asphalt Trailer Visited
Issues Summary • Funding and Personnel Availability • Payment of Officers • Rates (overtime vs straight pay) • Benefits & Retirement
Recommendations: Agencies should consider... • Developing written guidelines to address: • situations where UPOs recommended • work zone traffic control planning process • officer pay/benefits, work procedures, etc. • Training UPOs in proper MUTCD work zone signage and flagging procedures.
Recommendations: Agencies should consider... • Gathering better data on traffic safety incidents at Federally funded highway work zones in order to assess effectiveness of work zone traffic control techniques. • Using new technologies, such as automated enforcement and intrusion alarms, as well as UPOs.
