Road pricing simulations : Traffic, land use and welfare impacts for Austin, Texas

摘要: This article explores the traffic, land use and welfare impacts of road pricing in Austin (Texas, USA) region, including introduction planned toll roads, bridge tolls, a downtown cordon toll. Different tolling strategies are examined, fixed versus variable rates. The travel demand model (TDM) incorporates joint mode time-of-day choice models, as well multinomial destination choice, relying on full feedback times costs. Austin-calibrated DRAM-EMPAL models used to predict future household job distributions. Results include traffic redistribution over space time, long-term location changes, traveler implications. While proposed roads generate revenues enhance options, their estimated project costs not exceeds such benefits. In addition, tolls expected successfully redistribute while area appears highly sensitive tolls.
