Better traffic control needed for Colindale Avenue NW9

0 have signed. Let’s get to 200!


Summary

The situation with parking outside the waiting restriction hours on Colindale Avenue NW9 between Ajax Avenue and Charcot Road is getting worse, and is posing very high risks to all road users.  We request the London Borough of Barnet to implement additional 24-hour parking restriction on the appropriate section(s) of Colindale Avenue between Ajax Avenue and Charcot Road.

Background

The current waiting restriction for Colindale Avenue between Ajax Avenue and Charcot Road is Monday to Saturday 8am to 6:30pm, and there is no waiting restriction on Sunday.  The extent of the waiting restriction, the “At any time” waiting restriction and existing bus stops are shown in this graphic (click here).

Colindale Avenue is served by three bus routes providing an important east-west link for Colindale Tube Station, and is used heavily by the Metropolitan Police Service accessing Colindale Police Station, and the NHS Blood and Transplant service which is located behind Colindale Tube Station.

There are two issues that need addressing as a matter of urgency by Barnet Council:

  1. Traffic turning onto Colindale Avenue from Mornington Close
  2. Severe congestion on Colindale Avenue between Mornington Close and Charcot Road

Issue 1 - Traffic turning onto Colindale Avenue from Mornington Close

Whenever someone tries to join Colindale Avenue from Mornington Close outside the waiting restriction period, the driver finds it extremely difficult to turn onto Colindale Avenue because the sight line is completely blocked by vehicles parked on the single yellow line on Colindale Avenue between Mornington Close and Guardian Avenue.

Vehicles usually start parking on the single yellow lines from 6pm Monday – Saturday, and the whole of Sunday (and certain bank holidays when waiting restriction is not enforced by Barnet Council).

The photos below show the typical condition of Colindale Avenue at the junction with Mornington Close outside the waiting restriction period.

As you can see from the photos above, there is no way that anyone can have a clear sight line of what is coming down on the westbound carriageway of Colindale Avenue.  We are aware of a number of near misses between vehicles, bicycles and motorcycles travelling at high speed on the westbound carriageway of Colindale Avenue and traffic leaving Mornington Close due to extremely poor sight line from Mornington Close.

Although TD42/95 (Geometric Design of Major / Minor Priority Junctions) of Volume 6 of Part 6 of the Design Manual for Roads and Bridges is not necessarily applicable to non-trunk roads, this document suggests a 70-metre sight line from a minor road for a T-junction (see Table 7/1 of TD42/95) assuming that the sight line is not blocked by vehicles parked on the main road.  The photos above clearly demonstrate that it is not achievable from Mornington Close.

There was in fact a head-on collision between two cars at about 7:30pm (outside the waiting restriction period on Saturday 29th April 2018 (Met Police reference number 7070) outside 95 Colindale Avenue due to reduced carriageway width as a result of vehicles parking on the westbound carriageway of Colindale Avenue outside the waiting restriction hours.

Rule 243 of the Highway Code advises road users not to park within 10 metres of the corner of a junction except in an authorised space.  Please note that failure to comply with the rules of the Highway Code does not in itself cause a person to be prosecuted.  There is currently no specific provision in Highways Act 1980 and Traffic Management Act 2004 regarding parking within 10 metres of the corner of a junction.

For Issue 1, we urge the Council for London Borough of Barnet to go through the necessary Traffic Regulation / Management Order process and change the waiting restriction from “Monday – Saturday 8am – 6:30pm” to “at any time” (i.e. double yellow line) on the westbound carriageway of Colindale Avenue between Ajax Avenue to 120 Colindale Avenue to provide a better sight line for drivers leaving Mornington Close.

Issue 2 - Severe congestion on Colindale Avenue between Mornington Close and Charcot Road

Outside the waiting restriction period, there are always vehicles parked on the single yellow line outside 137 / 139 Colindale Avenue immediately opposite to Guardian Avenue - see photos below:

Colindale / Guardian Ave 01

Colindale / Guardian Ave 02

These vehicles are parked outside 137 / 139 Colindale Avenue without considering the tight turns / give ways by buses and other large vehicles between the traffic island and Guardian Avenue.

Given the close proximity of the single yellow line on the westbound carriageway of Colindale Avenue between Mornington Close and Guardian Avenue, the vehicles parked outside 137 / 139 Colindale Avenue usually cause an initial congestion which could tail back easily back to the entrance to Public Health England on the west and back to the bus stop near Colindale Gardens sales office on the east when buses or large vehicles approach from either end and they have to give way to each other.

This photo was taken opposite 121 Colindale Avenue on Sunday 3rd June 2018 at approximately 12:45pm showing a typical condition on a Sunday.

This photo shows a typical view of a pedestrian finding it difficult to cross the road using the traffic island facility outside 128 Colindale Avenue (Costa Coffee), and vehicles giving way to oncoming traffic

It is also worth pointing out that the kerb stone on this traffic island as seen in the photo above is frequently dislodged by wide vehicles trying to move into the centre line of Colindale Avenue due to vehicles parked on the westbound carriageway about 15 metres downstream of the traffic island.

The following video links provide evidence of the problem on a typical day outside the waiting restriction period:

  5. Aerial footage on Sunday 7th April 2019 at 12:30

For Issue 2, we urge the Council for London Borough of Barnet to go through the necessary Traffic Regulation / Management Order process and

  1. change the waiting restriction between 105 Colindale Avenue and Charcot Road from “Monday – Saturday 8am – 6:30pm” to “at any time” (i.e. double yellow line); and / or
  2. implement yellow box / KEEP CLEAR road markings on Colindale Avenue at the junctions with Guardian Avenue and Charcot Road.
