  • Late 1950’s early 1960’s saw exponential growth … did it really relay on the automobile?

    1. 1. Placing Pedestrians First at Toronto’s Signalized Intersections Bruce Zvaniga, P.Eng.Manager, Urban Traffic Control Systems
    2. 2. Outline1. Toronto Context2. Transportation Plan for Sustainable Growth3. Recent Improvements to Pedestrian Signal Operations4. Wish List for Future Improvements January 11, 2009
    3. 3. Toronto’s Population • Population 2.5 Million (5.5 Million in Region) • One-seventh are over 65 years of age (fastest growing age group) January 11, 2009
    4. 4. General Characteristics ofToronto’s Signal Operation• 2100 traffic signal-controlled intersections• Roughly one-third fixed-time operation and two- thirds semi-actuated• Transit signal priority at one of every six intersections• All signalized intersections are connected to central systems: 64% in-house time-of-day, 20% TransSuite and 16% SCOOT January 11, 2009
    5. 5. Transportation Growth• 75% growth in both AM inbound and outbound vehicle flows to entire city over past 20 yearsHowever,• 66% of inbound trips during the AM to the central area are by transit …the vast majority of these trips include some walking January 11, 2009
    6. 6. Transportation Plan forSustainable Growth January 11, 2009

    8. 8. Pedestrian Countdown Timers • Addresses confusion/uncertainty • Council approved 3 year city-wide implementation to be completed June 2009 concurrent with LED Conversion • Countdown of clearance (flashing don’t walk) phase only • Issues with variable clearance timing where rail, fire hall, and transit pre- emption present • Public, political, media and police reaction very positive January 11, 2009
    9. 9. Leading Pedestrian Interval4 second headstart for pedestrians before vehicle greenStatus:• Removed quickly at “normal” intersection• Retained and highly successful at intersection of one- way street with heavy left-turning traffic to a two-way street• Plan is to “try” another 5 to 10 locations in 2009 - looking for intersections with similar unopposed turning movements, and heavy pedestrian movements on conflicting crosswalks January 11, 2009
    10. 10. Accessible Pedestrian Signals(aka audible pedestriansignals) • Council policy decision to include APS at all new traffic signal installations and to target retrofits within a year of receiving a request. • 250 intersections currently equipped • 60 additional retrofits targeted in next 2 years • Questions remain about how to handle complex intersection geometrics January 11, 2009
    11. 11. Increased PedestrianCrossing Time• Old method: – Walk speed 1.2 m/s or 1.0 m/s – Ped clearance was timed for 5/8ths of the minimum total time• New method: – 7 second minimum walk, full clearance distance at 1.2 m/ s walk speed … walk plus clearance time must allow for 1.0 m/s walk speed• New method only applied after installation of countdown timers• Impact on transit priority infrastructure – due to relationship between loop detector placement and time to decision point – somewhat less efficient January 11, 2009
    12. 12. Pedestrian Signal Priority • Barnes Dance • Exclusive Pedestrian Phase • Pedestrian Scramble January 11, 2009
    13. 13. Pedestrian Signal PriorityPerceived Benefits• Clear message that pedestrians are important• Increase pedestrian comfort level• (May) improve safety• Low cost, easy to implement ? January 11, 2009
    14. 14. Pedestrian Signal PriorityChallenges • APS • PCS • Signs & Markings January 11, 2009
    15. 15. Pedestrian Signal PriorityBlind and Visually ImpairedPeds• Issue of audible tone – “Walk Sign is on for all crossings”• Concerns expressed about confusion – Lack of parallel traffic sound – How does a visitor detect the difference ? – Confusing for guide dogs … who do you follow – Need for tactile way finding – Concern about crowding around APS buttons – Lack of distinct north-south vs. east-west tones January 11, 2009
    16. 16. Pedestrian Signal PriorityCountdown Signals Display• Issue caused by concurrent and priority phasing• PCS count down the clearance time• Crossing clearance on the diagonal is greater than the orthogonal• PCS devices use simple logic – count down time based on the previous display time January 11, 2009
    17. 17. Pedestrian Signal PrioritySigns Signs: • To sign or not to sign • Are the signals intuitive or susceptible to misinterpretation? Markings: • Full diagonal or stub January 11, 2009
    18. 18. Pedestrian Wish List forTraffic Signals 1. Pedestrian Detection SAP SAC issue 3. PII – pedestrian infrastructure integration …. low cost handheld device using DSRC to communicate information to peds (particularly visually-impaired) January 11, 2009
