Pilot program: Speed sensors trigger red light on Philly road
Philadelphia Inquirer ^ | Tuesday, November 19, 2013, 2:01 AM | Robert Moran

The speed limit on Kelly Drive near Fountain Green Drive is 35 mph, but the average speed of motorists is nearly 55.

In an attempt to slow everybody down, the city has installed sensors in the roadway that determine the speed of vehicles approaching Fountain Green, about a half-mile north of the Girard Avenue Bridge.

If a vehicle passes the sensor going above the speed limit, the light at Fountain Green turns red. …

In another safety measure, the city will add a nonslip surface on Kelly Drive next year to help reduce accidents on rainy days, (acting Streets Commissioner David J.) Perri said. …

Interesting concept. Sequenced lights timed to the speed limits would accomplish the same thing.

The unintended consequences of this will be epic.

They do that plenty here in Texas. I have heard that it is even against state law, but whatever.

Using red lights to regulate, slow down, and even stop traffic is common.

When I was in college, we "discovered" that the lights on the main roads were timed - to about 10mph over the speed limit.

It's almost like the cities were encouraging you to speed. Surely, they'd never do that. It's all about safety, not revenue...

Timing them AT the speed limit will result in massive pile-ups (since in reality virtually no one is driving at the limit)

I think they work at other speeds too.

Speed sensors cost more. So the companies which manage the revenue enforcement systems push them.

Philly would be much better off spending time solving their feral youth problem.

Ahhh.... you miss the point, entirely.

Feral youth abatement cost money

Auto speeder lights raise money

They should replace the red lights in Philly with a big red middle finger. That’s their attitude.

If the cops want a far less expensive and more effective means of getting people to slow down...

I suggest the next time they retire a police cruiser, they simply park it on Kelly Drive near Fountain Green Drive and place a mannequin in the driver seat sporting a full policeman's uniform. They could even set up a relay connected to a simple circuit that would randomly flash the lights to achieve the look of a real cop in the cruiser.

Move its location occasionally but I guarantee that the average speed of motorists will be very near or under 35 mph. And it costs the town next to nothing.

Bad concept, imho. It would be much better to use these detectors to sync up the green lights with the flow of traffic, to keep everything running smoothly. Instead, they are going to do the opposite and clog up their streets even more.

Also, the proposed stopping of traffic will increase the emission of CO2.

All traffic enforcement is about revenue.

I live in an area with limited traffic and the most congested area is getting on and off one of the freeway exits. Every so often I see the traffic engineers messing with the timing and when they get it wrong, it is amazing what a bad result they can get.

Worse, this punishes those not speeding

The speeders and non speeders alike are caught at the light.

A few good speed bumps carefully designed to look like pothole would be a better alternative

That said the only time I have been to Philly I was speeding as fast as I could out of town

I'm not a traffic engineer, but I will never understand this incessant struggle to irrationally slow speed limits.

The street in this article is 35 MPH, but most motorists travel it at 55 MPH. Studies have been done that prove motorists generally travel at speeds that are intuitively comfortable, hence most motorist in this story are NOT going 35. Therefore, the likely appropriate speed is, in fact, probably closer to 55 than it is to 35. But the speed Nazis want ticket money and believe that “for the children” everyone should drive at 10 MPH.

There is a major highway near were I live. This highway speed limit is set at 55 MPH, yet at one section of the highway the road narrows and the shoulders of the road are close to the lanes. At this section of the road most motorists traveling this highway naturally, and always SLOW DOWN. The speed limit is 55. The highway was designed for 55+, but motorists almost always travel at comfortable speeds.

Just yell, “SAFTEY” and you can get almost any road speed limit reduced to stupid speed. I want to travel at ludicrous speed!

The average speed is 54.8mph ,, sounds like the people have spoken and they feel that 55 is a safe speed for this 4 lane highway (the photo shows that this borders a body of water so there is no traffic entering from side streets) .. the article mentions frequent accidents .. my first thought is that the few people driving 35 and the masses at 55 create the problem ,, simply raising the limit to 45 or 50 mph would greatly reduce the mismatch in speed between cars and reduce the accident rate.

“I suggest the next time they retire a police cruiser, they simply park it on Kelly Drive near Fountain Green Drive and place a mannequin in the driver seat sporting a full policeman’s uniform.”

That’s exactly what’s done in the town just north of mine. Everybody knows about it so everybody ignores it and speeds on by.

I like the way you think ... see reply #21 ... We are embarking on a massive widening program where I live that will be a PITA for many years ,, if they really want to increase road capacity by 15-20% I can do it in a week ,, just increase the posted speed limit from 50/55 to 70.. JOB DONE ... If the road was safe for the shit cars we had in the 1950’s and 1960’s at 65 it surely is fine for todays cars at 70.

My hometown of Nampa, ID, did that a few years ago (actually, I think it was a wrecking yard that put the car out). They removed it after the dummy inside was found to have several bullet holes in it.

There’s an old joke about Kelly Drive during the AM rush hour, which is truly bumper to bumper at a HIGH rate of speed.

Goes like this: Dude was in his Volkswagen, looked down at his speedo, and it showed he was doing 55 mph.

It was then that he noticed his engine had stopped.

You have to drive that damn thing to understand how really close to reality that joke was.

You know I have plenty of complaints about living on the left shore of America.

But one thing is aok.

I never get nailed for speeding. And I do it a lot.

Got a ticket driving in Chicago for one day. But it has been quite a while since I got stopped out here.

It seems the cops have plenty of other things to worry about.
