Incorporating Pricing Strategies into the NEPA Project Development Process Patrick DeCorla-Souza Federal Highway Administration TRB Transportation Planning Applications Conference May, 2007
Reducing Demand with “Substitutes” • Alternative modes • Transit - fare reductions, service improvements • Ridesharing – HOV time and cost advantages • Convenience – pre-trip and on-trip traveler information • Alternative destinations • Telecommuting • Alternative times • Flextime, staggered work hours
Reducing Demand with Congestion Pricing • Combine “push” with “pull” strategies • Toll SOV in peak periods • Free service for HOV, park-and-ride, etc. • Reduced transit fare, frequent service, etc. • Examples: • Bridge pricing - Bay area and NYC: HOV toll discounts • Cordon pricing –Stockholm and London • Expressway pricing - Singapore • Parking pricing – Southern California
Need Both “Pull” and “Push” for Success in Reducing Demand • “Pull” strategies are necessary but not sufficient: • Reduction in delays due to such shifts will cause “replacement” of reduced traffic by those who had previously been deterred by congestion • To ensure that congestion does not return – total user-borne cost for driving must stay the same • Delay “cost” must be replaced by money cost – a congestion toll
Congestion Pricing Potential • Traffic reduction: • 15% in London • 20% in Stockholm • 71% of eligible motorists shifted time of travel at least once a week to get toll discounts in Ft. Myers, Florida • In Singapore, expressway traffic flows freely in the peak periods 95% of the time

Preventing Flow Breakdown with Congestion Pricing • Toll “price” to manage demand for use of freeway: • Does not waste a resource (time) as in ramp metering • Toll cost is not a “wasted” resource – revenue can be used to reduce taxes, pay for alternative modes, or generate additional benefits • Main issues: • Motorist may decide to divert to alternative routes • But if lost throughput is regained, this will not increase congestion -- total vehicle throughput and speed will actually increase (e.g., I-66 example)
