Research Projects 2004/05 Tunnel emergencies:emergency evacuation Expansion joints for integral bridges Use of mechanical ventilation in tunnel emergencies Effectiveness of washing bridges

Research Value Management Workshops

Value Management Workshops: Development of the R&D Programme: New proposals received (Oct 04) Bids collated and evaluated Proposed projects prioritised Programme matched to available resources Draft programme to HA Board (Jan 05) Submission to the Minister (Feb 04) Approval by the Minister (April 05)

Value Management Workshops: HA Research Themes: Accessibility Asset Use Driver information Improved safety Integration Reducing congestion Sustainability

Value Management Workshops: The Essential Criteria: Benefits must be clearly identified Proposals must be feasible/achievable Proposals in line with HA objectives

Value Management Workshops: Criteria used for 2005/06: Improving safety Reducing congestion Reducing environmental impact Enhancing driver information Optimising WLC More effective technical governance Speeding up delivery Developing Traffic Operator role Wider benefits

Value Management Workshops: Scoring: Benefits Score of 0 – None benefits Score of 10 – Exceptional benefits Likelihood – Score (0 - 10)

Research Value Management Workshops Proposed Research Projects for 2005/06

Proposed New Projects 2005/06 Early application of waterproofing systems to bridge decks Impact of revised HSE Standards on tunnels Assessment rule s for web stiffeners in steel bridges Half- joint bridge testing Temperature effects on integral bridges Design and strengthening of bridges for vehicle impact (desk study) Assessing defect acceptance in FRP materials Steel fibre-reinforced concrete – Concrete Society Report
