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 کاملBayesian Modeling of the Microscopic Traffic Characteristics of Overtaking in Two-Lane Highways
Bayesian Networks are employed to model the uncertainty hindering in the overtaking behavior of young drivers in two-lane highways and reveal the traffic related microscopic characteristics that may influence the decision to overtake. Results using data from an experiment conducted on driving simulator show that male drivers, on average, accept smaller gaps for overtaking than female drivers. F...
متن کاملStatistical Analysis of Two-lane Roundabout Data for Traffic Control Decision-Making in an Urban Area
Researches using existing statistics and data collected from the area of study help officials at decision-making, to improve the region's problems, like the problem of the high rate of accidents in the region, despite the low volume of daily service. The uses of roundabouts in many parts of the world have many advantages over intersections, amongst them are increased safety and capacity and red...
متن کاملA method for simplifying the analysis of traffic accidents injury severity on two-lane highways using Bayesian networks.
INTRODUCTION This study describes a method for reducing the number of variables frequently considered in modeling the severity of traffic accidents. The method's efficiency is assessed by constructing Bayesian networks (BN). METHOD It is based on a two stage selection process. Several variable selection algorithms, commonly used in data mining, are applied in order to select subsets of variab...
