Gap acceptance of pedestrians at overpass locations

Transportation Research Part F: Traffic Psychology and Behaviour, 2018
Abstract Most of the studies related to pedestrian behavior focus on signalized intersections while a few focus on overpasses. In this study pedestrians’ behaviors at overpass locations are investigated. For this purpose, two overpass locations were selected and pedestrians either using the overpass or crossing illegally were recorded by video ...

Gap Acceptance at Priority-Controlled Intersections

Journal of Transportation Engineering, 2011
Critical gap is the threshold by which drivers in the minor stream judge whether to accept a gap. If the gap is larger than critical gap, drivers accept it and enter the intersection; otherwise, drivers reject the gap and wait for the next gap. At a priority-controlled intersection, critical gap is usually considered as a fixed value or to follow a ...

Interference Between Traffic Flows: The Gap Acceptance Theory

2020
This chapter presents the gap acceptance theory, in that it is of great applicative interest in studying road intersections. Therefore, some models for estimating the critical gap and the follow-up time for at-grade unsignalized intersections and roundabouts are described.

The Intersection Delay Problem with Correlated Gap Acceptance

Operations Research, 1966
This paper considers a modification of the single-car intersection delay problem in which the waiting driver, upon finding a suitable gap for crossing also examines the succeeding one, and uses it if it is larger. It is shown that the additional delay time caused by this method of gap acceptance is generally quite small.

Gap-Acceptance Problems at a Traffic Intersection

Applied Statistics, 1971
A driver who is waiting at a give way sign on a minor road and who wishes to turn into the major‐road stream is faced with a series of gaps on the size of which he must base his decision to cross. This paper reviews the problems involved in the collection and analysis of accepted and rejected gaps, and illustrates them with data from a particular ...

The Analysis and Interpretation of Gap Acceptance Data

Transportation Science, 1970
Alternative methods of analysing gap acceptance data are considered with a view to removing the bias implicit in the situation in which minor road vehicle drivers exhibit consistent behavior and all accepted and rejected gaps are taken into account.

Analysis of gap acceptance in a complex traffic manoeuvre

European Journal of Operational Research, 1980
Abstract Gap acceptance functions are useful descriptions of the turning behaviour of vehicle drives at intersections. For simple manoeuvres, where a driver crosses or merges with a single stream of traffic, such functions can be obtained from empirical data using easily-computed statistical methods. For more complex turning movements, where a driver

Practical determination of gap-acceptance parameters on roundabouts

International Conference on Road and Rail Infrastructure, 2018
Roundabouts have various benefits in terms of safety and capacity issues that are worldwide recognized. Capacity analysis, which is very often key factor in the decision-making process between different types of intersection, can be performed with the empirical regression or gap-acceptance based models.

Gap Acceptance and Risk Analysis at Unsignalised Intersections

1991
In order to explore the possibility to use the critical gap acceptance as an intermediate variable related to accident risk, an exploratory study has been designed including eight intersections on rural roads in the south of France.

Gap acceptance at unsignalised intersections

2008
Review the methods for estimating gap acceptance and to estimate the critical gap at unsignalised T- intersections in Singapore, focusing on three movements: left turn from the minor road, right turn from the minor road and right turn from the major road, covering 2-lane and 4-lane major roads in suburban (non-CBD) traffic conditions.
