• Evaluation of Different Trip Purpose to Road Pricing Scheme
  Abstract: Cordon pricing is an effective policy to alleviate congestion and manage travel demand in city centres. However, different responses among road users to certain policies are inevitable. This paper presents a study evaluating the possible consequences of cordon and parking pricing on road users with different trip purposes, i.e., workers and non-workers. Different models have been developed and calibrated with data from the central business district of Mashhad, using revealed and stated preference methods. The analysis of the interviewee responses to the hypothetical situations shows that workers comprise the dominant proportion using each mode of travel to Mashhad CBD. The commuters were provided with alternative choices, and their preferences were examined using multinomial logit. The results show that the cost-based policy such as parking and cordon pricing is good to reduce congestion as it affects workers, but the impact is more evident for non-workers traveling to the CBD. Furthermore, the model suggests that workers are more likely to shift mode in response to changes in travel time.

• Effects of Full-Facility Variable Tolling on Traveler Behavior: Evidence from a Panel Study of the SR-520 Corridor in Seattle
  Abstract: Variable tolling was implemented on the SR-520 Bridge in the Seattle region as part of a federally funded initiative to reduce traffic congestion. SR-520 tolls vary by time of day up to a maximum of $3.50 each way ($5 for non-transponder payments). A nearby parallel facility, Interstate 90, remains as a toll-free alternative across Lake Washington. Tolling was accompanied by investments in public transit and traffic management technologies and by efforts to promote telecommuting. This paper uses a two-stage panel survey approach to analyze the impacts that this tolling program has had on corridor users’ daily travel choices. In each survey wave, over 3,000 respondents from roughly 2,000 households completed a two-day travel diary, with additional detail on trips in the Lake Washington corridor, plus a personal survey on general travel behavior and attitudes.Key survey findings include a marked decrease in respondents’ travel in the corridor after tolling, particularly on SR-520, which experienced a 47% reduction in recorded trips, and significant diversion to I-90. Shifts from SR-520 to I-90 were most pronounced among males, those in lower-income households, and those with less workplace schedule flexibility. There were also increases in transit mode share in the corridor, while carpooling and telecommuting levels were relatively stable. In the post-tolling survey, respondents registered an overall increase in satisfaction with their commutes and less stress associated with driving. Reported satisfaction with the speed and reliability of individual trips on SR-520 also increased substantially, and personal attitudes shifted slightly in favor of tolling.
