Evidence in the literature shows that automated and human driving modes demonstrate different characteristics, i.e., headway policy, spacing reaction time, comfortable acceleration, others. These differences alter observed traffic dynamics have an impact on energy consumption. This paper assesses footprint of commercially implemented adaptive cruise control (ACC) systems drivers car-following f...

In this paper, we propose and analyze an online, decentralized policy for dispatching vehicles in a multi-line public transit system. the policy, arriving at terminal station are assigned to lines starting round-robin fashion. Departure times selected minimize deviations from certain target headway. We prove that is self-organizing: given there sufficient number of available vehicles, timetable...

Using survey data, we examined Medicaid supplemental payments (SPs), including disproportionate-share hospital (DSH) and upper payment limit (UPL) payments in 2005 and changes in these payments between 2001 and 2005. We found that states increased their use of general funds in financing of DSH payments while expanding the size and scope of other SPs considerably. Although the federal government...
