1 TCRP A-40 Manual to Improve Safety at the Platform-Train- Interface (PTI) Kate Hunter-Zaworski and Dylan Anderson Oregon State University Uwe Rutenberg, RDI

2 Problem Platform-Train-Interface (PTI) Gap between train and platform edge Most common incidents: Tripping Over Gap Falling Into Gap 1 Kirse, 2007

3 Key Issues Depend on Platform Height 2

4 Track Geometry 3

5 Operations Engineering Platform Track Vehicles Future Solutions Map Advanced technology for Intrusion Detection Platform screen doors for Intrusion Prevention 4

6 Operations Creating a Culture of Safety-Rail Daily Safety Briefing Incident Prevention Active suicide prevention program Staff training 5

7 Operations People Safety Ambassadors Platform Conductors Community Partnerships Outreach with local Crisis Centers Operation Lifesaver Education K -12 6

8 Public Relations & Marketing Audio announcements Signage on trains and in stations Courtesy Counts Watch the gap stenciled on platform Videos Internet/application based: Dumb Ways to Die e/real/1_dumb_ways_to_die.jpg 7

9 Engineering-Platform based gap fillers Polypropylene and wooden rubbing (edge) boards Platform extension LA Metro (angle bar) Devadoss,

12 Track Geometry-Maintenance Ballasted Track Extra rods and extended ties to prevent track movement in stations Regular inspection (vertical and horizontal) Self and non self levelling cars 11

13 Looking into the Future Platform Intrusion DETECTION PREVENTION 12

14 Intrusion Detection Visual type Sensors CCTV with advanced analytics Thermal Imaging Laser sensors Doppler Radar Physical Sensors Pressure mats 13

15 Intrusion Prevention-Platform Screen Doors 3 Primary Configurations: Full Height HVAC Benefits Noise Suppression Almost Full Height Less HVAC Benefits Noise Suppression Half Height 14 Keevil and Hulse, 2013

16 Platform Screen Doors Reduce guideway intrusions and service delays Require consistent train configuration Reduce station dwell time Expensive to retrofit 15

17 Platform Edge Fencing Platform edge fences with 14 foot wide gang ways ( Coaster-NCTD) 16

18 Between Car Barriers Platform Based Solution: Platform Bollards LA Metro Car Based Solution: Chains Bungees Striped Elastic Straps San Francisco MUNI

20 Conclusions Operational Solutions Safety Culture Staffing Public relations and outreach programs Community partnerships Engineering Platform height & track geometry dependent Low tech rubbing boards to platform screen doors 19

21 Unexpected findings Stairs and Escalators are the real problem need additional investigation Data challenges between FTA and FRA reporting Desire from industry to harmonize reporting requirements Classification of intentional trespass or suicide 20
