Upstream Signalized Crossover Intersection

Transportation Research Record: Journal of the Transportation Research Board, 2006
Left turns have a significant impact on the operation and performance of signalized intersections. Therefore, researchers have investigated alternative measures to improve the performance of intersections with heavy left-turn movements, some of which have been unconventional schemes.

Upstream Signalized Crossover Intersection: An Unconventional Intersection Scheme

Journal of Transportation Engineering, 2006
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.

Intersection of selenoproteins and kinase signalling

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2013
The small, obscure group of selenoprotein oxidoreductases and the huge clan of kinases, the workhorses of cellular signalling, are rarely discussed together. Focusing on selenoproteins of unknown structures, we predict a thioredoxin-like fold for the Selenoprotein N (SelN) family and use the structure to rationalise effects of the muscular myopathy ...

Crash Estimation at Signalized Intersections

Transportation Research Record: Journal of the Transportation Research Board, 2006
Longitudinal intersection crash data are observations on a cross section of intersections that are observed over several time periods. Such cross-section and time series data structures have positive temporal correlation within each intersection. Using the basic negative binomial regression leads to invalid statistical inference due to incorrect test ...

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 ...

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.
