Stochastic Algorithm for Improved Operations at Isolated High Speed Intersections
The current practice of specifying simultaneous gap out logic at isolated high speed signalized intersections places constraints on the signal controller logic that cannot be satisfied under high congestion level. Further, it often results in degraded signal efficiency and dilemma zone protection. A stochastic approach is proposed in this paper with the objective of increasing safety and effici...
متن کاملAn Improved Algorithm for High-speed Floating-point Addition
This paper describes an improved, IEEE conforming oating-point addition algorithm. This algorithm has only one addition step involving the signi cand in the worst-case path, hence o ering a considerable speed advantage over the existing algorithms, which typically require two to three addition steps.
متن کاملOptimal Advance Detector Location for Green Termination Systems on High-Speed Isolated Rural Intersections
This study seeks to identify the optimal location of an advance point traffic detector (APTD) to support green termination algorithms for enhanced dilemma zone protection systems at high-speed isolated signalized rural intersections. This is done by developing a nonlinear optimization model with the objective to maximize the opportunities to predict empty dilemma zones during a look-ahead time ...
متن کاملModeling of Signal Plans for Transit Signal Priority at Isolated Intersections under Stochastic Condition
Transit signal priority TSP is recognized as having the potential to improve transit service reliability at small cost to general traffic. The popular preference for TSP encounters the challenges of various and challenging test scenarios. According to the stochastic characteristics of traffic flow, the signal timing model was established for TSP at an isolated signal intersection, where the pas...
متن کاملSafety impacts of signal-warning flashers and speed control at high-speed signalized intersections.
For many years, to reduce the crash frequency and severity at high-speed signalized intersections, warning flashers have been used to alert drivers of potential traffic-signal changes. Recently, more aggressive countermeasures at such intersections include a speed-limit reduction in addition to warning flashers. While such speed-control strategies have the potential to further improve the crash...
