Signals on Cambridgeshire’s guided busway meant to give priority to buses

Cambridgeshire County Council has changed the way a set of traffic lights aimed at giving priority to buses using the guided busway in St Ives operates – because cyclists have discovered how to trigger the sensors and get themselves a green light too. The local authority says the issue is adding to congestion in the town.

The junction, where the guided busway meets Harrison Way, has a traffic light controlled crossing intended for use by people on foot and bike, reports the Hunts Post. But some cyclists realised that staying on the guided busway and activating the sensor as they rode past would change the lights.

A council spokesman said: “An engineer went to adjust the lights after we got reports that cyclists were triggering them. Since the changes we’ve had no reports of this happening.

“The cycle route along the guided busway continues to be used by many cyclists. There’s been lots of sunshine and using this cycle route is a great way to get outdoors to enjoy the summer whether you’re commuting or cycling for leisure.”

The Hunts Post says that a number of drivers have claimed that the time spent to negotiate Harrison Way has lengthened since the guided busway came into operation in 2011, though the council disagrees.

It adds that two years ago, a volunteer-staffed transport and environment working group surveyed traffic on Harrison Way and in a report to St Ives Town Council that during morning rush hour from 7am to 9am, the lights turned red every two minutes, for an average of 21 seconds.

That meant that during those two hours, traffic was held at the lights for a total of 23 minutes each morning.

Connecting Cambridge with St Ives and Huntingdon, the guided busway opened in August 2011 and covering 25 kilometres is the longest such facility in the world.

Born in Scotland, Simon moved to London aged seven and now lives in the Oxfordshire Cotswolds with his miniature schnauzer, Elodie. He fell in love with cycling one Saturday morning in 1994 while living in Italy when Milan-San Remo went past his front door. A daily cycle commuter in London back before riding to work started to boom, he's been news editor at road.cc since 2009. Handily for work, he speaks French and Italian. He doesn't get to ride his Colnago as often as he'd like, and freely admits he's much more adept at cooking than fettling with bikes.

the Harrison Way lights turned red every two minutes. The survey said each time the lights were red for an average of 21 seconds

Is that with or without cyclists setting off the sensor?

How long do cyclists have to wait at red lights?

Story short on details.

21seconds every two minutes is certainly nothing to complain about.

"That meant that during those two hours, traffic was held at the lights for a total of 23 minutes each morning."

Unbelievable. They mean motor traffic on the road was held. The cycle traffic, using this 12 mile route to one of the biggest areas of employment in Cambridge, used by huge numbers of people to get to work by bike, can go hang.

This just makes me wonder...?

If riders are having to use a separate sensor to trigger access across a junction then doesnt this mean the cycle provision there is pretty poor or not working?

How are riders expected to cross via council plans there?

And how long is the wait for their own green?

As HKCambridge says - given how many use said route - is there enough riders to outweigh the driver frequency across said junction? I also don't think the wait motorists have claimed is that bad - there are many junctions I have seen in Hampshire that are a LOT worse and a lot longer a wait.

Isn't this change contrary to the Cambridgeshire local transport plan policies? Got any friendly county councillors?

The blighters who devised this anti-cycling technology - they've not caught the We Hate Cyclists Disease (WHCD) currently rampant in the New Forest, have they?
There is also a strain of this sickness among people in the Box Hill area of Surrey where drivers complain of being held up by riders.
I've become so concerned that I may be holding up drivers I often flag them down and offer to give them my telephone number, so they can phone me each morning with their intended route which I promise to avoid using at the same time.

I used to love cycling in Germany, you have traffic lights for cyclists which get priority. I once met a friend stuck in traffic on one side of town. I was on my bike I managed to get across town, and 10Km's out of town before she caught up with me. That was riding legally, using their infrastructure in the 90's. Why don't these planners & councillors take a trip over and have a look. Oh and while they are at it they could learn how to do recycling properly too  3

Hand up, I'm guilty of doing this. Admitting not at rush hour though. Discovered it by accident, as was fed up of the tocan crossing, didn't expect the lights to change for me, but to my surprise they did! The correct option is a shared use pedestrian/cyclists lights are really slow to change, as well as needing to ride on shared use pavements which are narrow and slow on a road bike. The bus route is on smooth tarmac, you cycle straight up to and the lights went green. Significantly quicker, but alas no more.
