  1. M1 Junctions 7 - 10 High Occupancy Vehicle (HOV) Lane Presentation for PCM International Scanning Tour 15th June 2006

  2. Format of talk - History of scheme to date - Project organisation - Proposed scheme features - Problem areas • Empty lane fears • Eligible vehicles • Variable signing issues • Layout issues • Enforcement • Operational issues

  3. Scheme location plan

  4. Background • Already proposing to widen M1 from dual 3 lane to dual 4 lane standard • 160,000 vpd now • Rising to over 200,000 vpd by 2023 • M1 is key part of motorway network • Introduction of HOV lane would be a very late scheme change • Only 3 HOV schemes on local roads in UK

  5. Scheme history • July 04 Secretary of State requests HOV feasibility study from Highways Agency (HA) • Nov 04 Initial HOV Feasibility Study report • Dec 04 M1 HOV pilot announced by Secretary of State • Mar 05 M1 motorway widening contract awarded • Mar 06 Start of works on M1 widening J6A to 10

  6. Scheme history • Jul 05 Scheme Brief for HOV lane issued by Dept for Transport(for a low-tech solution) • Summer 05 to May 06 HOV “Before Monitoring” traffic surveys • May 06 Draft Preliminary Designs and VISSIM micro-simulation completed (revisions ongoing)

  7. Future programme • Jun 06 Ministerial Submission summarising design proposals • Jul 06(?) Secretary of State approval to complete HOV design and start construction • Jan 08 (earliest) to Dec 08 (latest) Staged opening of M1 HOV Lane??

  8. Project organisation 5 key strands • Before & after monitoring • Operational strategy • Enforcement strategy • Marketing & publicity • Scheme design and safety case

  9. Design Features • Layout and Operation • Length: Approx. 11km (7 miles) between J7 and J10 • Lane 4 – Solid white line separation and 2+ lane marking • Non-segregated - Access and Egress at any point • Overhead gantry signing – variable signs (rotational prisms?) • 24/7 operation of lanes • Eligible Vehicles • Eligible: 2+cars, motorcycles, (and buses ? ) • Excluded: HGVs, Single Occupancy Taxis, Towing Vehicles

  10. Current Traffic Flows Traffic Flow Summary, 2006 • 2+ represents only a small proportion of all vehicles in the AM and PM peak periods (typically 8% to 15% of all traffic). • 2+ vehicle demand is close to the 500 vehicle minimum HOV lane threshold (476 vehicles J10-J9) in 2006. • Higher number of 2+ vehicles in the Inter Peak and especially at weekends. • HGVs represent between 14% and 29% of all traffic on weekdays.

  11. Forecast HOV usage Microsimulation Traffic Forecasts, 2008 & 2023 Forecast HOV Usage(2+ vehicles choosing to use the 2+lane) 2008 AM Peak: 300-660 vehs 2008 PM Peak: 250-630 vehs Represents 60% of all eligible vehicles at best, but could be as low as 25%) By 2023: 480-920 vehs (Represents 55%-70% of all eligible traffic) Non-eligible vehicles and HOVs choosing not to use can be accommodated in adjacent 3-lanes (max. V/C ratio 0.91).

  12. Eligible vehicles

  13. Signing Rotational Prisms Signing

  14. 2+ Lane Arrangement First advance sign for (Lane 4) 2+ lane Northbound >> << Southbound

  15. 2+ Lane Arrangement Second advance sign with countdown Northbound >> << Southbound

  16. 2+ Lane Arrangement Start of 2+ lane Northbound >> << Southbound

  17. 2+ Lane Arrangement Advance sign for End of 2+ lane Northbound >> << Southbound

  18. 2+ Lane Arrangement End of 2+ lane Northbound >> << Southbound

  19. 2+ Lane Arrangement Lane 4 merges with Lane 3. Lanes 1 and 2 continue ahead. Northbound >> << Southbound

  20. Enforcement A police function, but:- • Not a high priority issue • Resource intensive • Safety concerns over stopping offenders on high speed roads • Payment for police time is contentious

  21. Enforcement Automatic enforcement • Camera technology not proven Penalties • Current regulations do not suit HOV • New legislation needed to change level of fines (£30/£60) • Are penalty points appropriate for non safety related offence

  22. Compliance Likely solution for M1 trial:- • Occasional Police campaigns • Some Police patrols • Regular Traffic Officer patrols • Observation platforms • High visibility camera trial • Warning letters

  23. Operational Issues Scenario 1: Lane 1 closed, 2+ lane opened to all traffic

  24. 50 50 50 50 Operational Issues Scenario 1: Lane 1 closed, 2+ lane opened to all traffic 2+ lane sign alerts of end of designation Accident Slow down

  25. 50 50 50 Operational Issues Scenario 1: Lane 1 closed 2+ lane opened to all traffic Lane 1 traffic instructed to change lanes. 2+ lane ends. Accident Slow down

  26. 40 40 40 Operational Issues Scenario 1: Lane 1 closed 2+ lane opened to all traffic Lane 1 Closed. 2+ lane open to all traffic. Accident Slow down

  27. 60 50 50 50 Operational Issues Issue 1: Should variable speed limits be applied? Congestion

  28. Operational Issues Issue 2: Should slow moving HGVs (and Buses) be banned from lane 3?

  29. Any questions??
