How We Manage Our Roads

In this section you can find out more about how we manage and maintain these roads and plan for the future

The Project Control Framework

On 1st April 2008 we launched the Project Control Framework. The Framework sets out how we, together with the Department for Transport, manage and deliver major improvement projects.

2.2.1 Syndicate Group 1 - Safety & Maintenance

Leeds Stakeholder Workshop

2.2.1 Syndicate Group 1 - Safety & Maintenance

Job Title Organisation
Area Watchman Carillion WSP
OD Assistant Project Sponsor Highways Agency
Development Control Highways Agency
Transportation Consultant Hyder Consulting Limited
Representative Transport Activists Round Table

Group findings were as follows:

Route Functions:

Matrix as proposed by Hyder was approved although it was felt that a grading of the functions may be useful e.g. % applicable to either local, regional or strategic. The RMS Guidance may require review to adopt this approach

Distribution of commuter workplace destinations is widespread within the Leeds conurbation; destination is key which is relevant to LU/DCS and lack of use of public transport

Safety

  1. The initial list of issues are all of importance and should be given priority in the RMS
  2. M621 Closely spaced junctions. Accidents reduced during maintenance when a 30mph rather than 50mph speed limit was imposed.
  3. Is there a correlation between time of day and accidents? Would variable speed limits help?
  4. Incident delay and accident costs need to be quantified
  5. Access management on M621 should be considered especially for Leeds/Leeds trips- Is it technically/politically possible and who would benefit?
  6. On M621 should congestion/safety be maintained on route rather than off route?
  7. Issue S4 relating to safety of vulnerable users should relate to junctions

Economy

  1. Memorandum of Understanding - is it successful in dealing with Objective 1 issues e.g. are consents coming out? How can we decide on objectives C2/C3 relating to Land Use & Development Policy /Objective 1 without knowing the answers to the aforementioned questions. Further, is it sufficiently transparent?

Environment

  1. Climate Change - SWYMMS indicated a 25-30% increase in emissions. Area wide charging for reduction in emissions preventing trip length increases.

Access/Integration

  1. Issues listed are acceptable.
  2. Is Park and Ride always beneficial?

Operating the Network

  1. O4 - Reduce congestion: are small increases not significant?

Improving the Network

  1. N3 - standing traffic reduction is favoured

Maintenance

  1. Can TPI/ATM works be programmed to run with major maintenance?
  2. Co-ordination with local authorities? And also adjacent areas? NRSWA co-ordination required.
  3. Formal identification of start of tapers is being developed (M1)
Safety Options
Option No. Option Description Some Advantages Some Disadvantages Rating

OS1

Rest areas off existing junctions

Provide relief for drivers fatigue

Additional land required

If facilities are required, need investment from external developers

If no facilities, it will be less used by drivers

Need routine maintenance for facilities

2

OS2

Emergency refuge areas

Incident Support Units

Limited land required

Allow emergency pull in when hard shoulder is used

Safer for stopped vehicles than stopping on continuous hard shoulder

Discontinuous relief

May be hazardous to pull out of refuge

May be hazardous if used by others at the same time

1

OS3

Anti-swoop (diamond) road markings prior to diverges

Discourage unnecessary lane changing

Limits weaving areas

2

OS4

Emergency access routes off the main carriageway

Central Reserve crossovers are preferable combined with lane control

Enable access for emergency vehicles during incidents

Additional land required

Would be used during non-emergencies if not properly protected

Need maintenance (overgrowth)

3

OS5

Speed enforcement systems (egg cameras)

Improves speed compliance

No land required

Provide alternative additional funding

Effective only at location of enforcement systems

Require police enforcement

1

OS6

Queue management systems/variable speed limits

     
Economy Options:
Option No. Option Description Some Advantages Some Disadvantages Rating

OC1

Implement land use and development control policy to protect the operation of the motorways

Maintains the operation of the route, helping to make sure that developments are directed away from already problematic locations

Help to identify capacities for development and other land use

Supports RPG and other processes

May conflict with economic aspirations of authorities

May not be concurrent with plans of developers

1*

OC2

Provide improved information on congestion and incidents

Enable better planning of journeys

The majority of drivers do not plan their journeys.

When they do plan their journeys, it is not done immediately before the journey, when latest information is available

1

Maintenance Options:
Option No. Option Description Some Advantages Some Disadvantages Rating

OM1

Eliminate day time maintenance works

Will improve flow during day times.

Will increase cost and duration of work

Some restriction or lane closure may still be required during day time

Alternative hazards due to night time working would exist

2

OM2

Investment in replacement infrastructure (lighting/ safety barriers) with lower maintenance requirements

Over a period of time this will reduce maintenance costs

Benefits will not be immediate

1

OM3

When required use ARMCO wire where wider reserve permits

Doesn't catch snow - less build up

1

OM4

Cast concrete central barriers

Can tolerate reduced central reserve width

More robust - hence less maintenance
