Pedestrian Safety at Signalized Intersections

T&DI Congress 2014, 2014
Nationwide, more than 47,000 pedestrians were killed between 2000 and 2009, representing about 12% of the total highway traffic fatalities. In addition, nearly 700,000 pedestrians were injured over the same period. In Florida, one in every five traffic-related fatalities is a pedestrian, making pedestrian safety a top priority for safety improvements ...

Modeling Queues at Signalized Intersections

Transportation Research Record: Journal of the Transportation Research Board, 2004
Traffic control is one of the most effective techniques for a road manager to adapt network capacity to flow. It also provides possibilities to modify users' choices of modes and routes. An important area of research is formed by the dynamic assignment problem, in which the effect of delays at controlled intersections is taken into account.

Signalized Intersections: 1950 Through 1980

2020
Perhaps the most complex point in any traffic network is the signalized intersection. At a typical signalized intersection with four entry approaches on two two-way streets, there are 12 vehicular movements (4 approaches, each with a left-turn, through, and right-turn movement), four crosswalk pedestrian flows, and bicycles that must be taken into ...

Delay Variability at Signalized Intersections

Transportation Research Record: Journal of the Transportation Research Board, 2000
Delays that individual vehicles may experience at a signalized intersection are usually subject to large variation because of the randomness of traffic arrivals and interruption caused by traffic signal controls. Although such variation may have important implications for the planning, design, and analysis of signal controls, currently no analytical ...

Upstream signalized crossover intersection

2004
The impact of left turns on operation is probably the most significant factor in the performance of conventional intersections. As a result engineers have looked to alternative measures for dealing with left turns at intersections to improve performance, some of which have been unconventional schemes. The purpose of this thesis is to introduce a new

Simulation of Signalized Intersection Model

Applied Mechanics and Materials, 2013
Signalized intersection delay is an important evaluation index of the signalized intersection capacity and level of service. This paper presents a signalized intersection delay model for signalized intersection. The model uses time series and queuing theory.

Signalized Intersections: 1985 Through 2000

2020
Between 1980 and 1985, the Highway Capacity and Quality of Service Committee moved to adopt a signalized intersection methodology based upon critical movements. This approach to timing and analysis of signalized intersections had been used by Bruce Greenshields in the early 1950s, and had been developed by Don Berry and others.

INTERSECTION SIGNALING SIMULATION

2017
The number of vehicles registered to traffic increases rapidly every year in Turkey. According to Statistics of The Number of Road Motor Vehicles published by Turkish Statistical Institute, the number of vehicles registered increased by 72% during the period of last 10 years in Turkey.

Intersection of Signal Transduction Pathways and Development

Annual Review of Genetics, 2006
One of the challenges of modern biology is to understand how cells within a developing organism generate, integrate, and respond to dynamic informational cues. Based on over two decades of intensive research, many parts and subroutines of the responsible signal transduction networks have been identified and functionally characterized.

Interactions and intersections of plant signaling pathways

Journal of Molecular Biology, 1999
Plant signal transduction is a rapidly expanding field of research, and during the last decade a wealth of insight into how plants perceive and transmit signals as part of normal development and in response to environmental cues has been and is continuing to be unraveled.
