Key Findings

Dulwich Village / Calton Avenue/Court Lane junction – Can the junction cope with the volume of traffic? Morning

 Calton Avenue is over saturated or over capacity i.e. this arm has too much traffic for the junction to cope with, which means that long queues are formed.  Dulwich Village northbound and southbound is near saturation i.e. this arm of the junction is reaching its limit to cope with traffic, so queues are formed.  Turney Road has spare capacity, i.e. this arm of the junction can accommodate additional traffic.

Afternoon

 Calton Avenue is over saturated, this arm has too much traffic for the junction to cope with, and so long queues are formed.  Dulwich Village northbound and southbound is over saturated: this arm has too much traffic for the junction to cope with, so long queues are formed.  Turney Road is at capacity: this arm of the junction is reaching its limit to cope with traffic, so queues are formed.

When are the busiest hours? In the morning, weekday traffic levels are high between 7am and 10am.

In the afternoon weekday traffic levels are high between 3pm and 8pm.

Typical residential streets in Southwark carry on average around 3000 motor vehicles per day – as can be seen above, Turney Road, Burbage Road and Court Lane are carrying significantly higher volumes of traffic than this.

A typical ‘B Road’ in Southwark carries on average around 8000 motor vehicles per day – Dulwich Village is carrying far more traffic than this.

Major roads like Lordship Lane and East Dulwich Grove are carrying comparable traffic at the peak time to residential roads such as Burbage Road and Dulwich Village.

Dulwich Village / Calton Avenue /Turney Road Junction :How does northbound traffic compare with southbound ?

Morning Peak:

 Dulwich North is the busiest arm of the junction, with most traffic going northbound, toward Red Post Hill.

Afternoon Peak:

 Dulwich Village south is the busiest arm of the junction , with most traffic going southbound (If Calton Avenue is closed and traffic from Turney Road is restricted then southbound traffic on Dulwich Village will be reduced).

Generally there is more traffic on Dulwich Village, south of Calton Avenue than on the northern section. This is due to significant traffic turning right into Calton Avenue in the AM or exiting from Calton Avenue going southbound.
