Microscopic modelling of freeway operations

Bunker, Jonathan M. - 2006

, 1994) uses empirical macroscopic relationships between speed, flow and density to quantify freeway operations and … of freeway operations at the specific locations under consideration. The models needed to be able to be calibrated using … developed contain the principal processes of freeway operations, merging and lane changing. Gap acceptance theory was applied to …

Optimal Freeway Ramp Control without Origin-Destination Information

Zhang, Lei; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2004

This paper develops an analytical framework for ramp metering, under which various ramp control strategies can be viewed as ramifications of the same most-efficient control logic with different threshold values, control methods, and equity considerations. The most-efficient control logic only...

Travel Time Variability After A Shock: The Case Of The Twin Cities Ramp Meter Shut Off

Zhang, Lei; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2001

Ramp meters in the Twin Cities were turned off for 8 weeks in the Fall of 2000. This paper analyzes travel time variability with and without ramp metering for several representative freeways during the afternoon peak period. Travel time variability is generally reduced with metering. However, it...
