A traffic count on Tonbridge High Street, 13,600 vehicles per day

Tonbridge High Street 1st March 2017

I did a quick traffic count on Tonbridge High Street a few days ago.

It showed that at about 17:00, there are about 1,360 motor vehicles per hour using the road.

Using the rule of thumb, 10x hourly peak traffic = day traffic, that gives 13,600 motor vehicles a day using Tonbridge High Street.

Putting this into perspective for cycling,

  • London Cycle Design Standards give a critical failure to any street where total volume of motor traffic is > 1,000 vehicles/hour at peak and cyclists are not separated. Green is <200 vehicles per hour at peak.
  • The Welsh Active Travel Guidance gives a critical failure to any street where total volume of traffic is > 10,000 vehicles per day, and cyclists are not separated. Green, is 2,500 vehicles per day.
  • The UK LTN2/08 says that for > 10,000 vehicles per day, cycle lanes or tracks are required.

So, Tonbridge High Street is not a place where many people would find it comfortable to cycle.
