Regardless of COVID, DOT Actually Stepped Up Transit Sign Precedence This 12 months – Streetsblog New York Metropolis


The hassle to assist buses transfer sooner is … transferring sooner!

Regardless of reported delays within the rollout of Transit Sign Precedence know-how for MTA buses, the Division of Transportation will reveal later at this time that it has exceeded its aim and put in the know-how — which supplies or extends inexperienced lights for buses — at roughly 1,382 intersections citywide.

In 2017, the town had stated it hoped to put in TSP at 1,200 intersections — however engineers have quickened the tempo at which they conduct their site visitors research and had been in a position to configure 461 intersections throughout this COVID-fractured 12 months alone.

One of many newly TSP’d corridors is E. 149th Road within the Bronx, the place DOT Commissioner Polly Trottenberg is scheduled to spotlight the company’s achievements at a press convention at 11 a.m. Additionally available might be Craig Cipriano, president of the MTA’s bus division.

“That is going to be vastly necessary for bus speeds,” Cipriano informed Streetsblog. “Once we do TSP and different remedies like devoted bus lanes and enforcement cameras, our buses full their runs as much as 20 p.c sooner.”

The DOT will reveal 14 key bus corridors which have gotten TSP this 12 months:

  • Manhattan
    • Madison Avenue, serving the uptown M1 and M4
    • Fifth Avenue, serving the downtown M1 and M4
    • 14th Road, serving the M14A/B SBS
    • Ninth Avenue, serving the M11
    • West Finish Avenue, serving the M57
    • Seventh Avenue, serving the M2
    • Eighth Avenue serving the M20
  • Staten Island
    • The S74/S84 hall
    • The S44/S94 hall
    • Hylan Boulevard, serving the S79 SBS
  • The Bronx
    • E. 149th Road, serving the BX19 (bus speeds on this route had been among the slowest within the metropolis, round 3.9-4.3 miles per hour, in accordance with the MTA).
  • Queens
    • Merrick Boulevard, serving the Q5, X63, Q17, Q3, Q30, Q36, This autumn, Q42, Q77, Q84, Q85
  • Brooklyn
    • 18th Avenue, serving the B8.

The ridership on these 14 corridors, pre-COVID, was 233,934 a day — all of whom will profit from sooner buses.

The faster tempo of putting in TSP represents a change in method from 2018, when Trottenberg said the company would give attention to intersections relatively than complete corridors. As well as, DOT engineers had been initially unable to maneuver rapidly as a result of finding out the site visitors affect of TSP on a given intersection required huge quantities of pc time to a number of pc simulations to plot the best period of time to shave off of cross road site visitors at a given intersection.

However that digital logjam was damaged, in accordance with DOT Deputy Commissioner Josh Benson, when engineers began utilizing the MTA’s dwell “bus time” feed. Through the use of the dwell telemetry from buses as they journeyed on their routes, engineers may in a short time see, in actual time, what occurred in the event that they flipped just a few switches (or, extra precisely, moved round a bunch of ones and zeroes on their screens) to vary gentle timing.

“It took a few years to develop this new system and we’re reaping the fruits of it this 12 months,” Benson stated. “The trade commonplace after we began doing TSP in 2006 was to construct elaborate pc simulation fashions, however the computing took hours and days earlier than you get outcomes. And then you definately’d make a small tweak within the mannequin, and it could take hours or days to get the brand new consequence.

“Now we are able to see in a day if we have to maintain the inexperienced for six seconds or 10 seconds,” Benson added. “You may see how a bus is transferring, make a change, and see if it labored.”

Advocates have complained on the delays to wider set up of TSP, and Cipriano understood the way it regarded from their aspect.

“With TSP, it’s simple for me to say, ‘Let’s have TSP at each intersection tomorrow,’ however a street has many customers: motorists, bicyclists, pedestrians and the bus riders. It has to work for everybody,” he stated.

Benson claimed that DOT’s Transit Sign Precedence engineering is all about ensuring pedestrians don’t get screwed. With TSP put in, buses talk their location to site visitors indicators, which then maintain a inexperienced gentle longer if a bus is in vary or shortens the time a bus will spend at a pink gentle whether it is already stopped.

“For those who solely cared about buses, you would prioritize the bus, and TSP could be very simple,” Benson stated. “However that’s too easy a approach to take a look at it. Pedestrians want time to cross a road and we are able to’t reduce the minimal time we give pedestrians — which is the time from when the ‘Don’t stroll’ hand begins flashing. If the sign cycle is in that flashing hand interval, the bus can’t obtain the TSP profit.”

With the dwell bus time knowledge, site visitors engineers can see patterns on any given line — equivalent to bus stops which can be situated simply earlier than site visitors indicators. At such intersections, bus passengers wouldn’t profit from an early or prolonged inexperienced gentle as a result of the bus has to cease to choose up new passengers or drop off departing ones.

“Bettering bus speeds is collaborative,” Cipriano stated.

When pressed by Streetsblog, Cipriano admitted that his perfect collaboration with DOT could be to get the company to ban vehicles from nearly each roadway so buses can transfer freely.

“I’m the largest advocate for the bus system and bus prospects,” he stated, “so I might need the entire metropolis to be a busway. We wish buses to have extra precedence, forward of vehicles, and everybody. However we dwell in a metropolis with many modes of transportation.”

The town is at the moment constructing 20 miles of car-free busways and devoted bus lanes this 12 months, which is not nearly as much as the MTA wanted, however it’s greater than the town has ever finished in a single 12 months.

“My boss stated she needed 60 miles,” Cipriano stated, “however it is a good begin.”

Friday’s announcement of the TSP corridors can even embrace some Citi Bike information (although Streetsblog readers must wait till the press convention to search out out what it’s) and a reminder that bus lane enforcement cameras will go into impact on E. 149th Road on Friday, beginning with warnings for the subsequent two months earlier than the cameras begin spitting out tickets, which begin at $50 and may escalate to $250 for a fifth violation in a one-year interval.

E. 149th Road was chosen as the placement for the press convention to indicate off the potential for main enhancements. The cross-Bronx roadway has transit sign precedence at 21 intersections in all.
