Seminar 23rd November 2001 Other Policies: Demand Management & Highway Investment Professor Marcial Echenique
Other Policies: Demand Management & Highway Investment 1. Background: Cambridge Sub-Region 2. Demand Management • Principles • Practice • Proposed Tests 3. Highway Investment • Need for Extra Roads • Proposed Strategy 4. Conclusions
1. Cambridge Sub-Region - Background • 21% increase in households between 2001-2016 = 42,000 • Allocation of dwellings - Allocated ~ 20,000 In City ~ 2,000 Outside ~ 18,000 - To be allocated (Structure Plan) ~ 22,000 In and around the City ? 10,000 Outside the City ? 12,000 • Extra daily trips (8 per household) ~ 336,000 In and around the City ~ 120,000 Outside the City ~ 216,000 • Potential Car Trips ~ 240,000 In and around the City (50% of trips) ~ 60,000 Outside the City (83% of trips) ~ 180,000 • Potential peak hour car trips ~ 40,000 In and around the City ~ 10,000 Outside the City ~ 30,000
Congestion in the Sub-Region 2010 Source: East of England Regional Transport Strategy ▬▬ Heavy Congestion ▬▬ Peak Congestion ▬▬ Operating Satisfactorily
2. Demand Management • Principles - Adjust demand (by pricing) to available supply - Efficiency: Allocation of scarce resource Increases speed Increases effective capacity Reduces waste of resources (fuel & time) - Environment Less emissions Less noise - Social equity Improves bus performance Political difficulties
Practice - Singapore since 1975 Reduced traffic Increased speeds by 20% - average 37.5 miles per hour Increased revenues - Norway since 1990 Oslo, Bergen & Trondheim Money used for infrastructure improvement - London is implementing a £5 vehicle charge in Central London
Proposed Tests - Cordon Charging Peak Hour (7-10; 15-18) £5.00 ? Off Peak (rest of day) £2.50 ? Residents within cordon £0.50 ? - Second Best: Workplace Parking Charges Daily £2.50 ? - Third Best: Increase in parking charges 10-100% for on-street parking Probable annual revenues up to 50 million to be used for investment in infrastructure (Public Transport, Highways, Cycleways, etc.) Measure social impacts Measure environmental impacts
3. Highway Investment • Need for extra roads - Demand increase to dispersed destinations - Access to important employment centres Addenbrookes University West Site Northern Fringe Eastern Area - Linking of Park & Ride Sites and Edge Locations - Recognition of extra capacity needed: CHUMMS - Political difficulties
4. Conclusions • Needs to introduce both: - Demand restrictions (Pricing) - Supply increases in Public Transport, Cycling & Pedestrian Routes, Highways • Measure Impacts - Efficiency (cost-benefit) - Social (impacts by S.E.G. and areas) - Environmental (emissions, energy, accidents, etc.)
