Introduction

  • Why 20mph for Glasgow’s Streets?
  • What is Edinburgh doing about 20mph?
  • Glasgow’s road network: how big is it, what kinds of roads does it

comprise?

  • A brief historical review of the installation of 20mph areas in Glasgow
  • A comparison of the installed 20mph areas and pedestrian and cycle

accident distributions

  • Conclusions

– Where are We Now With 20mph in Glasgow? – What Can We Do?

Why 20mph for Glasgow’s Streets?

  • Reduction in the number and

severity of traffic collisions

  • Improvements to the

environment

  • 20mph urban speeds currently

supported by – Scottish Government – Glasgow City Council – Road safety, cycling and disabled support groups – Opinion polls show that most people want to live on a 20mph street

A brief Historical Review of the Installation of 20mph Areas in Glasgow

  • In 2010 GCC initiated installation of

20mph zones on residential roads

– Phases 1 to 4 (163km) complete or near complete (2015) – Phase 5 plan for 20mph zones in Dowanhill and the city centre with no traffic calming

  • Implementation Rate

– The 163km of Phases 1 to 4 have taken 5 years to complete – equivalent to a rate of 33km/year

  • Approximately 1350km of mainly

residential roads outstanding

  • At the rate of 33km/year another 40

years to complete 20mph implementation

In this time period, roughly 1695 accidents within the City of Glasgow were reported to police in which a cyclist was involved. That can be expressed as: 113 cycle accidents/year 0.90 accidents/km

Cycle Accident Point and Heatmap 1999- 2013

Accidents are largely concentrated on arterial roads with some streets in the West End, City Centre and Southside have accident rates 20x higher than Glasgow’s roads on average

Roads with the highest cycle accident rates have the accident points posted in colour (blue =male casualty, red = female casualty) On other roads, the accident points are shown as small black dots. Sections of the following roads are

ROUNDABOUTS & HOTSPOTS Concentrations of cycle accidents occur at specific locations, particularly at roundabouts These roundabouts are frequently on travel “desire” lines and are difficult for cyclists to detour around

The 10 locations figured on the left accounted for 5% of all cycle accidents for the period

Glasgow City Centre Accident Rates & Proposed 20mph Area

  • Glasgow City centre contains 43km of roads, 2.25% of the total non-motorway city road network
  • It accounted for 18.4% of the pedestrian accidents in the period 1999-2009 (8x higher rate per km than average)
  • It accounted for 8.2% of the cycle accidents in the period 1999-2013 (3.6x higher rate per km than average)
  • The city centre has very high pedestrian and cycling accident rates and the proposed 20mph zone is likely to reduce

both the numbers and severity of both

Conclusions

  • The city centre is the locus of the highest accident rates to vulnerable road
  • users. The current proposal for 20mph in this area (Mandatory 20mph

Zones (city centre)) should be warmly welcomed

  • 20mph speeds in residential areas are highly desirable but outside the city

centre the greatest proportion of accidents involving vulnerable road users is associated with the arterial roads, especially where these coincide with shopping streets. Significant sections of these roads must be brought into future 20mph schemes if accident rates and severities are to be reduced

  • This analysis has highlighted the egregiously dangerous nature of certain

roundabouts, especially where these are situated on dual carriageways. It is unclear if 20mph would be appropriate for these road junctions. Other means to reduce the accident rates at these hotspots must be urgently sought

Where are We Now With 20mph in Glasgow?

  • A petition to encourage Glasgow City to consider adopting a 20 mph

policy similar to that proposed in Edinburgh acquired 222 signatures by the closing date of 17th March 2015.

  • At a presentation to the Petitions Committee on the 12th May 2015, the

petition proposal received unanimous cross-party support and the committee instructed the Executive Director of Land and Environmental Services to submit a report to consider the pace and scale of phasing for the implementation of 20 mph speed limits within Glasgow

  • A report entitled “Review of Mandatory 20mph speed limit policy” has

now been scheduled for submission to the Sustainability and the Environment Policy Development Committee for discussion on 25th November 2015

  • Glasgow City Council currently has a public consultation for mandatory

20mph speed limits in the city centre and is seeking comments

What Can We Do?

  • Please assist GCC in its desire to slow the city centre to

20mph by supporting the proposed TRO, Mandatory 20mph Zones (city centre). Letters and emails of support can be sent up to the 30th November 2015 (more information at http://bit.ly/1XjJmZ1)

  • CTC members should consider pressing their council

representatives to support the extension of 20mph areas more widely across the city, to include arterial roads where high accident rates prevail

– Press for enhanced cyclist safety on roundabouts

Glasgow CTC 2015 AGM 3rd November 2015 MOTIONS

SLIDE 21

Glasgow CTC 2015 AGM MOTION 1

  • CTC Glasgow recognises from analysis of STATS 19 data

that the central area of Glasgow has rates of cycling and pedestrian accidents many times higher than the city as a whole.

  • CTC Glasgow therefore welcomes the proposed Traffic

Regulation Order to implement mandatory 20mph speed limits within the city centre.

  • This motion is to seek approval from the CTC members

attending the Glasgow CTC 2015 AGM, for the Glasgow CTC committee to send a communication to Glasgow City Council supporting this proposed TRO.

Glasgow CTC 2015 AGM

MOTION 2

  • CTC Glasgow recognises that reducing road speeds to 20mph can

result in major harm reduction to vulnerable road users as well as improving the urban environment.

  • CTC Glasgow strongly supports the move by cities such as

Edinburgh to make 20mph the default speed limit on all residential roads and major sections of arterial roads.

  • This motion is to seek approval from the CTC members attending

the Glasgow CTC 2015 AGM, for the Glasgow CTC committee to send a communication to Glasgow City Council urging them to extend 20mph speed limits to the majority of the city’s streets, and in particular to apply these to arterial roads which are shown from STATS 19 data to have comparatively high accident rates.

11/4/2015 22

slide-23
SLIDE 23

Glasgow CTC 2015 AGM MOTION 3

  • Analysis of cycle accident data (STATS 19) shows that some

roundabouts and junctions have unacceptably high accident rates.

  • The roundabouts tend to be situated on dual carriageways

which coincide with cycle desire lines. They are hard for cyclists to avoid.

  • This motion is to seek approval from the CTC members

attending the Glasgow CTC 2015 AGM, for the Glasgow CTC committee to send a communication to Glasgow City Council urging them, as a matter of urgency, to explore ways to make the identified roundabouts and junctions with higher accident rates safer for cyclists
