Early Empirical Evidence For The Effects Of Adaptive Ramp Metering On Measures Of Travel Time Reliability, Travis Charles Low
Early Empirical Evidence For The Effects Of Adaptive Ramp Metering On Measures Of Travel Time Reliability, Travis Charles Low
Master's Theses
Adaptive ramp metering (ARM) is a critical component of smart freeway corridors under an active traffic management portfolio. While improving capacity through smart corridors and application of proactive traffic management solutions is less costly and easier to deploy than freeway widening, conversion to smart corridors still represents a sizable investment for a state department of transportation. Early evidence of improvements following these projects can be valuable to agencies. However, in the U.S. there have been limited evaluations, of smart corridors in general and ARM in particular, based on real operational data. This thesis explores travel time reliability measures for the …

Exploring Travel Time Reliability Using Bluetooth Data Collection: A Case Study In San Luis Obispo, California, Krista Purser
Master's Theses
Bluetooth technology applications have improved travel time data collection efforts and allowed for collection of large data sets at a low cost per data unit. Mean travel times between pairs of points are available, but the primary value of this technique is the availability of the entire distribution of travel times throughout multiple days and time periods, allowing for a greater understanding of travel time variations and reliability. The use of these data for transportation planning, engineering and operations continues to expand. Previous applications of similar data sources have included travel demand and simulation model validation, work zone traffic patterns, …
