Increasing Capacity of an Isolated Merge by Metering its On-Ramp
Measurements taken downstream of freeway/on-ramp merges have verified that discharge flow diminishes when a merge becomes an active bottleneck. We show that metering the on-ramp can recover the higher discharge flow and thereby increase merge capacity. Detailed observations collected using video revealed that the outflow drop following activation was triggered by a queue that formed near the me...
متن کاملRamp Metering and Freeway Bottleneck Capacity
This study aims to determine whether ramp meters increase the capacity of active freeway bottlenecks. The traffic flow characteristics at twenty-seven active bottlenecks in the Twin Cities have been studied for seven weeks without ramp metering and seven weeks with ramp metering. A methodology for systematically identifying active freeway bottlenecks in a metropolitan area is proposed, which re...
متن کاملRamp Metering and the Capacity of Active Freeway Bottlenecks
The objective of this study is to determine whether ramp meters increase the capacity of active freeway bottlenecks, and if they do, how. The traffic flow characteristics at twenty-seven active bottlenecks in the Twin Cities have been studied for seven weeks without ramp metering and seven weeks with ramp metering. A series of hypotheses regarding the relationships between ramp metering and the...

the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
Development of A New Merge Capacity Model and the Effects of Ramp Flow on the Merge Capacity
Freeway merge areas are recognized as the most common segment of recurrent freeway congestion as two separate traffic streams join to merge a single stream. Over the years, several studies have attempted to explain and analyze a merge capacity phenomenon, however relatively few analytical techniques have been developed to evaluate the traffic flow in these areas. This study described a new inte...
