Analysis of Traffic Flow Variability on Two-Lane Highways
The main objective of this paper is to develop and test an approach for the spatio-temporal analysis of traffic flow variation on two lane highways. Traffic count devices located in several points of two lane highway links give the aggregate time series of data used in this approach, which is based on the Principal Components Analysis (PCA). The statistical analysis of main sources of temporal ...
متن کاملTwo-Lane Highways: International Perspective
The results of an extensive literature review of the safety performances of lowand intermediate-traffic-volume, two-lane rural highways are presented. The effects on traffic safety, as measured by accident rates, of pavement width, radius of curve/degree of curve, gradient, sight distance, traffic volume, and design speed on curved sections of two-lane rural highways are covered. The following ...
متن کاملModification of Webster’s delay formula under non-lane based heterogeneous road traffic condition
Delay is one of the most important performance measures of signalised intersections. Various models including Webster’s classical delay formula have been developed in countries with car dominated traffic stream to estimate average delay per vehicle at signalised intersections. Webster’s classical delay formula has been formulated under UK situation where the road traffic condition is homogeneou...
متن کاملFree-Gap Evaluation for Two-Lane Rural Highways
Transportation Research Record: Journal of the Transportation Research Board, No. 2223, Transportation Research Board of the National Academies, Washington, D.C., 2011, pp. 9–17. DOI: 10.3141/2223-02 Operating speed is most frequently represented by the 85th percentile speed (V85) of vehicles passing at a given road location, in a nonplatoon condition, and it is usually determined by spot speed...
متن کاملAlternative Design Consistency Rating Methods for Two-Lane Rural Highways
Design consistency refers to the conformance of a highway's geometry with driver expectancy. Drivers make fewer errors in the vicinity of geometric features that conform with their expectations. Techniques to evaluate the consistency of a design documented within this report include alignment indices, speed distribution measures, and driver workload. Alignment indices are quantitative measures ...
