The Montreal Avenue - King George Avenue 20mph zone in Chapel

Allerton

Some suggestions for improvements

Road signs - Diagram 674• The signs used in this

zone are to diagram 674, each with a child’s design below the statutory part of the sign

• This causes the statutory part to be too high and difficult to read – compare front and rear of sign at bottom of Gledhow Park Drive

Poor location of signs -1

• Some of the signs are difficult to read from a moving vehicle because of their location - for instance . . .

• Montreal Avenue and Church Lane from Harrogate Road

Montreal Ave/Church Lane (1)

Montreal Ave / Church Lane (2)

Gledhow Lane from Gledhow Valley Road

King George Ave - when turning into KGA southbound from Harrogate Road (right hand photo), it is

virtually impossible to see the signs

Woodland Lane – there is a lot of “clutter” around the right hand sign, making it difficult to read

Signs in other locations (1)

• The 20mph home zone in “the Methleys” is extremely well signposted and for the whole zone the 20mph limit is self-enforcing

Signs in other locations (2)

• In the village of Burley Woodhead there is a very “self-enforcing” 20mph zone – entry signs are clear, easily seen, unambiguous

• The traffic calming measures are simple and effective

TSGD 2002 – “the law of the land”

• Speed limits of 20 mph

• 16. - (1) The sign shown in diagram 674 may only be placed on a road if no point on any road (not being a cul-de-sac less than 80 metres long), to which the speed limit indicated by the sign applies, is situated more than 50 metres from a traffic calming feature.

Spacing of Traffic Calming Measures (1)

• King George Avenue, from Gledhow Lane roundabout southbound = 44 metres to first TCM, then 104 metres to next, then 78 metres, then 125 metres and 115 metres to exit sign at traffic lights

• The spacing of the TCM’s at the southern end of KGA do not meet the requirements of TSGD 2002, but the situation is better further up this road


• Gledhow Lane from GVR to Allerton Park = 495 metres, no TCM’s

• Gledhow Park Drive (east part)

from GVR to cushion at 5-way roundabout = 195 metres, no TCM’s

• Gledhow Park Drive (west part)

from King George Ave = 91 metres to first TCM,

then 145 metres to next TCM, and 154 metres to cushion at 5-way roundabout


• Gledhow Park Avenuefrom speed cushion near 5-way roundabout =112 metres to first TCM, then 374 metres with no TCM’s

• Gledhow Park Grovewhole length = 370 metres with no TCM’s

• Roxholme Grove from Harehills Lane to Gledhow Park Avenue = 260 metres with no TCM’s


• Woodland Lane, from TCM near Gledhow Lane, = 182 metres to junction with Regent Street, then a further 88 metres to next TCM near park, then 141 metres to TCM near Short Lane, then 116 metres to signs at zone entrance at Harrogate Road

• Regent Street, from junction with Woodland Lane to exit on to Harrogate Road = 133 metres

Other roads in the zone without any TCM’s at all

• Allerton Park• Pasture Avenue• Pasture Lane

• Norfolk Gardens• Northbrook Street• Victoria Street

• Well Lane• Hawthorn Road• Church Lane

• Dominion Avenue• Alberta Avenue• Hillside Road

SUMMARY

• 20mph zones should be self-enforcing• The signage at all the entrances to the zone

should be clear and easily visible, so that drivers know what the applicable limit is

• The traffic calming measures within the zone must be adequate to ensure the speed limit is observed

• This scheme does not meet these requirements and is therefore illegal
