Transferability of Fuzzy Models of Gap-Acceptance Behavior

open access: yes, 2011
The transferability of fuzzy models of gap-acceptance behavior between different intersections is evaluated in this paper using a method known as ROC curve analysis. The results of an application to four unsignalized intersections indicate that, even if transferred models generally perform adequately, intersection geometric and traffic characteristics ...

Response times in drivers' gap acceptance decisions during overtaking

open access: yesTransportation Research Part F: Traffic Psychology and Behaviour, 2023
Overtaking on two-lane roads can lead to increased collision risks due to drivers' errors in evaluating whether or not to accept the gap to the vehicle in the opposite lane.

Using gap sequences to estimate gap acceptance functions

Transportation Research Part B: Methodological, 1981
Abstract Traditional gap acceptance functions have been estimated based on the first gap observed. In this paper we show that the critical gap of drivers is decreasing on the average, as they are waiting for an acceptable gap. Our gap acceptance function is based on a probit model which assumes a normal distribution of gaps across gaps and drivers.

State‐dependent gap acceptance

Naval Research Logistics Quarterly, 1976
AbstractThis paper considers a traffic problem in which vehicles queue up according to a Poisson process on a single‐lane entrance ramp prior to merging into a major stream of vehicular traffic. In order to then prevent the ramp queue from becoming too large, a model is proposed which considers a lowering of the critical gap as the ramp queue size ...

Using Gap Analysis to Improve System Acceptance

Information Systems Management, 2006
Abstract The authors describe a user/customer needs gap model that can be used to develop a balanced approach to managing the gaps between business customer and end-user needs for new systems and the solutions that are deployed.

Gap-Acceptance and Empiricism in Capacity Prediction

Transportation Science, 1989
The paper compares the results of extensive measurements of the capacity of nonpriority traffic streams at major/minor junctions and roundabouts with the predictions of models based on gap-acceptance theory. There are significant differences in the form of the relation between the capacity and the traffic flows in the priority streams.

Driver Gap Acceptance Phenomena

Transportation Engineering Journal of ASCE, 1982
Results from a field study of gap acceptance characteristics of drivers executed merging maneuvers from stopped positions on side roads to main roads are presented. Gap acceptance parametrs are first estimated from the field data in an aggregated form and then for individual traffic flows observed on the main roads.

Gap-acceptance in road traffic

Journal of Applied Probability, 1968
We find the distribution of delay to minor road vehicles waiting to merge or cross a single stream of major road traffic. The decision to cross is taken on the basis of a gap-acceptance function. The model turns out to be a simple queueing problem in which a customer finding an empty queue has a different service time distribution from queueing ...
