Speed Management Action Plan

National Selection Criteria Criteria Description Fatalities The number of fatalities resulting from speeding-related crashes. Percentage Compares total fatalities in each State to those attributed to speedingrelated factors. Fatality Rate Shows speeding-related fatalities per 100 million vehicle miles traveled (VMT). Potential Reduction Estimates the number of fatalities that could be reduced in relation to the size of the transportation network. HSIP/SHSP Identifies and assesses elements contained within each Highway Safety Improvement Program and Strategic Highway Safety Plan. Opportunity Rates each State based on rankings for each criterion above. This Photo by Unknown Author is licensed under CC BY

State s Results 2012 FARS data 18 States

FSI Crashes Data Analysis Results Speeding-related Fatal/Serious Injury crashes account for 33% of all FSI crashes in Pennsylvania 6000 Fatal & Serious Injuries 5000 4000 3000 2000 1000 0 2012 2013 2014 2015 2016 2017 Year This Photo by Unknown Author is licensed under CC BY Total FSI Crashes Speed Related FSI Crashes

Speed Management What is a Speed Management Action Plan (SMAP)? Federal Speed Management Team Multimodal/Multidisciplinary is attacking the problem A Speed Management Action Plan can help Integrate SM concepts into other action plans and focus areas Provide collaboration opportunities engineering, driving behavior, education, and enforcement Prioritize short- and long-term SM actions This Photo by Unknown Author is licensed under CC BY

Data Analysis Approach Speeding is key factor in many safety areas Speeding is a cross-cutting issue Focus areas with potential speed management fatalities reduction: Roadway Departures Intersections Pedestrians & Bicycles This Photo by Unknown Author is licensed under CC BY

Data Analysis Results 80% 70% Percent Speeding-related FSI Crashes grouped by Focus Area 64% 73% 60% 50% 40% 30% 20% 17% 18% 10% 3% 5% 0% Roadway departure Intersections Ped/Bike Pennsylvania Nationwide This Photo by Unknown Author is licensed under CC BY

Roadway Departure Strategies 8 Pavement, HFST and drainage improvements Evaluate passing zones on twolane highways Rural ITS solutions Improve recovery area/clear zone Improve roadway design and geometric enhancements Consider road diets, pavement marking medians, lane reconfigurations, etc.

Intersection Strategies - Roundabouts - Revise geometry of complex intersections - Complete Streets to safely accommodate all road users - Enhanced ITS solutions & dilemma zone protection - Reduction of lane width markings - Advance intersection warning 9

Pedestrian/Bicycle Strategies Reduce exposure to vehicular traffic Improve signal hardware for pedestrians Improve shoulders/int for bike traffic Increase public awareness on bike/pedestrian safety Promote bicycle helmet use Accommodate bicycle use on roads 10

Linking SMAP to the 2017 SHSP

SHSP Strategies 1. Reducing Speeding & Aggressive Driving 2. Enhancing Safety in Work Zones Improve speed management and enforcement in work zones 3. Enhancing Safety on Local Roads Assist local agencies with speed limit guidance that analyzes operating speeds versus design speeds

Speed Management Action Plan What are we currently doing Analyzing signalized intersections with 40 & 45 MPH approaches

FATALITIES Crash Data Intersection Fatalities 120 Signalized Stop Controlled 100 80 99 82 80 105 86 89 102 103 100 87 60 40 20 0 2013 2014 2015 2016 2017 YEAR

CRASHES Crash Data Intersection Crashes 20,000 18,000 18,840 18,281 19,035 19,853 19,544 16,000 14,000 12,000 14,721 14,329 14,398 15,200 15,213 10,000 8,000 6,000 4,000 2,000 0 2013 2014 2015 2016 2017 YEAR Signalized Stop Controlled

Narrowing Down the Data Signalized Intersection crashes and fatalities are on the rise Year end reports were showing a negative trend for intersections despite intersection safety projects being completed every year A recent in-house study showed that not all intersection safety projects were resulting in respectable safety returns

Narrowing Down the Data In Pennsylvania, 32 percent of all intersection Fatal & Serious Injury crashes are speedingrelated at roads with posted speed limits between 40 to 45mph. Focusing on road sections with this speed limit range may lead to more effective fatality reductions. Provide direction to start at roads with posted 40 & 45 MPH Speed Limit - Page 14 of the Speed Management Action Plan

Data for Signalized Intersections & Speed Limits All signalized intersection locations The streets where these signals are located The speed limit of those streets Crash data at those intersections

Intersection Safety Review Reviewed 3,525 signalized intersections that met criteria Determined main crash type, main causation factor along other key factors o % running red light o % proceeding w/o clearance o % night time crashes o % speeding related

Collision Diagrams Created 5 collision diagrams for each county (335 total) 5 locations selected based on total crashes at intersection

Implementing Improvements HSIP funds are a possible funding source since SMAP is part of the SHSP Lower cost improvements can also be implemented by 715 funds or on capital projects Work with HOP units to address challenging intersections where new development is coming 26

NCHRP 17-76 (Guidance for Setting Speed Limits) PennDOT is a member Bob Pento is PennDOT s representative Project began in December 2016 Will complete final deliverables April 2019 Project will: Identify factors that influence operating speeds Provide guidance to make informed decisions related to establishing speed limits on roadways Oversight and research team includes Federal, State, & Local governments Texas Transportation Institute Michigan State University.
