Sentence examples for active bottlenecks from inspiring English sources

A series of hypotheses regarding the relationships between ramp metering and the capacity of active bottlenecks are developed and tested against empirical traffic data.

The traffic flow characteristics at 27 active bottlenecks in the Twin Cities have been studied for seven weeks without ramp metering and seven weeks with ramp metering.

Capacity drop at active bottlenecks is one of the most puzzling traffic phenomena, but a thorough understanding of its mechanism is critical for designing variable speed limit and ramp metering strategies.

In this study, within the framework of the kinematic wave theory, we propose a simple model of capacity drop based on the observation that capacity drop occurs when an upstream queue forms at an active bottleneck.

This can be directly concluded from the fact that there was never any significant congestion between the two triangular obstacles defining the narrowest part of the ramp, before the flow was controlled in this area from 16:02 on; this is clearly visible in the surveillance videos.62 An active bottleneck, in contrast, would be characterized by the formation of a queue [43].

This study aims to determine whether ramp meters increase the capacity of active freeway bottlenecks.

A methodology for systematically identifying active freeway bottlenecks in a metropolitan area is proposed, which relies on two occupancy threshold values and is compared to an established diagnostic method – transformed cumulative count curves.

One of the bottlenecks of an active control of turbulent boundary layers based on particle image velocimetry (PIV) measurements relates to the ability to process PIV images and extract useful for control information in real-time, on a time scale relevant for the selected control strategy.

Understanding the biological meaning of ROH length and their implications for inbreeding and population bottlenecks is an active area of research [ 24].

Having a large number of active WiMAX connections created a bottleneck in the system because of the amount of overhead associated with OFDMA reservation scheme.

For each structure, the active site entrance forms a bottleneck that was used to delimit the volume of the gorge in the calculations.
