As background information for the continued discussion about Warwick Road set out below are the comprehensive list of Traffic Management Options on Warwick Road and surrounding streets.

A.1 Ban right turn from Warwick Road onto NCR and left turn from York Road onto Brownlow Road
Advantages
Disadvantages
  • Addresses predominant rat-running movement, with potential to reduce northbound flow by over 60% during peaks
  • Scheme could be introduced on experimental basis
  • Some support for scheme at 2013 public meeting
  • Limited impact on other roads in wider area (apart from Brownlow Road, York Road & Maidstone Road)
  • Speeds not reduced (although could be combined with additional traffic calming measures)
  • Difficult to enforce banned turns in short-term (without approved CCTV enforcement cameras)
  • Residents in area also unable to turn right onto NCR and inconvenient alternative route
  • Possibility of longer queues on Brownlow Road (and delays for buses)
Deliverability
  • Requires TfL agreement to implement – issues raised about impact on NCR and delays to buses on Brownlow Road. Additional modelling may be required, which would delay scheme implementation
  • Risk of LB Haringey objection (due to impact on Maidstone Road)
  • Need for some public consultation (even if introduced experimentally) and objections likely due to inconvenient alternative route for those that want to head east along the NCR
  • Relatively high cost (particularly if enforcement camera(s) required)

A.2  Reduce green time for traffic exiting Warwick Road onto NCR
Advantages
Disadvantages
  • Makes route less attractive for rat-runners but maintains all movements at junction – would be supported by advance warning signs.
  • Quick to introduce and easily reversible if unsuccessful
  • Restricted green time could be focused on peak periods only to minimise inconvenience to residents
  • Limited impact on other roads
  • Speeds not reduced (although could be combined with additional traffic calming measures
  • Risk of longer queues in the short-term (until regular rat-runners find alternative route)
  • Residents may not perceive benefits
  • Could impact on York Road (and other roads) as drivers seek to avoid queues in Warwick Road. Additional measures might be required to mitigate this risk, increasing cost
Deliverability
  • Requires TfL agreement to implement (but likely to be supported as no adverse impact on NCR)
  • Could be introduced in the short-term
  • Monitoring arrangements would need to be agreed with TfL to measure impact on Warwick Road and Brownlow Road
  • Limited public consultation needed (particularly if introduced experimentally)
  • Very low cost (as signal plans already in place)

A.3      One-way maze
Advantages
Disadvantages
  • Makes route less attractive for rat-runners but maintains all movements at junction
  • Could be introduced experimentally and monitored
  • Minimal impact on NCR
  • One way working can lead to higher speeds (although could be combined with additional traffic calming measures)
  • Increased traffic in other streets in the maze, such as Bosworth Road, Natal Road and Wakefield Road.
  • Inconveniences some local residents by making them go the long way around
Deliverability
  • LBE has jurisdiction to implement scheme
  • Need to consult all affected streets and high risk of objections from residents in other streets in the maze – likely to delay implementation
  • Relatively low implementation cost

A.4      Road closure(s) to prevent through traffic
Advantages
Disadvantages
  • Would be highly effective in stopping rat-runners
  • Could be introduced experimentally and monitored, but would first need to assess likely impacts.
  • Minimal impact on NCR
  • Could encourage walking and cycling
  • Inconvenient for many residents
    in the area
  • Increased traffic on Brownlow Road
Deliverability
  • LBE has jurisdiction to implement, but must have regard to the impact on roads in Haringey. LBH may raise a statutory objection if, for instance, more traffic  was forced down Maidstone Road
  • TfL concern likely to be focused on impact (if any) on bus journey times on Brownlow Road
  • Possibility of objections from the emergency services (although gate for emergency services could be provided)
  • Need for wide public consultation and therefore scheme would take considerable time to implement
  • Probability of  objections from residents in the wider area that are inconvenienced by the closure(s)
A.5 Review existing banned turns at NCR/Brownlow Road and Bounds Green Road/ Brownlow Road
 
Advantages
Disadvantages
  • Reduces need for traffic to use Warwick Road (but may need to be complemented by other measures to deter continued use of Warwick Road)
  • Re-introduces conflicts into junction that would reduce pedestrian safety
  • Significant impact on operation of junctions, leading to additional queues and delays
  • Difficult to introduce experimentally as physical changes needed
Deliverability
  • TfL have rejected the idea of allowing general traffic to turn right from the NCR into Brownlow Road as this would conflict with pedestrians crossing Brownlow Road
  • LB Haringey have previously reviewed the junction of Bounds Green Road and Brownlow Road and rejected the re-introduction of the currently banned left turn as an all-red phase (which would be needed to allow pedestrians to safely cross) would cause severe delays.
  • High implementation cost as would require physical changes to both junctions
  • Unlikely to be implementable in the short-term, if at all

A.6 Signing to discourage through traffic
Advantages
Disadvantages
  •  Low cost
  • Quick to install
  • Additional visual intrusion in street
  • Ineffective
Deliverability
  • LBE has full control of scheme
  • No need for public consultation
  • May need authorisation from Department for Transport if non-standard
    signs proposed (risk of delay to scheme)


B)   Traffic Calming Options
B.1      Speed cushion/road humps/speed tables etc.

            Advantages
Disadvantages
  • Likely to achieve some speed reduction
  • No loss of on-street parking
  • Limited impact on through traffic
  • Cushions/humps outside homes can be unpopular due to noise and vibration that can result (previous cushions in Warwick Road have been removed at the request of residents)
Deliverability
  • LBE has jurisdiction to implement scheme (no approval from TfL required)
  • Limited need for public consultation (Warwick Road only)
  • Relatively low implementation cost
B.2      Pinch points/chicanes etc.
Advantages
Disadvantages
  • May achieve some speed reduction
  • Can incorporate trees etc. to enhance street scene
  • Limited impact on through traffic
  • Loss of on-street parking (more significant with chicanes) in an already heavily parked street.
Deliverability
  • LBE has jurisdiction to implement scheme (no approval from TfL required)
  • Limited need for public consultation (Warwick Road only)
  • More expensive than speed cushions etc.
