And here: Effects of an HOV-2 to HOT-3 Conversion on Traveler Behavior: Evidence from a Panel Study of the I-85 Corridor in Atlanta (187 pg pdf, Report for Federal Highway Administration, Apr.11. 2014)
Today we review before and after reports from two large American cities (Seattle, Atlanta) following introduction of congestion pricing on a bridge (Seattle) and on a HOV lane (Atlanta). Results indicate a decline of trips by 15-18%, a greater use of tolled segments by drivers with high incomes, a greater acceptance (40%) for tolling after introduction compared to before (25%) and a large drop in concern about the impact of tolling on low income users (from 74% to 57%). The key to successful implementation appears to be clear prior communication to the public on the need for congestion pricing.
