چکیده

1 Weaving is defined as the crossing of two streams travelling in the same direction along a 2 significant section of the road without the assistance of traffic control devices. Merging and 3 diverging vehicles need to make one or more lane-changes in a limited space and time, 4 determined by the weaving section length. This situation creates intensive lane-change 5 maneuvers, combined with heavy traffic volumes and variability in the speeds of the weaving 6 and non-weaving vehicles. This often results in safety and operational problems. 7 In the literature few studies developed crash prediction models for weaving sections. 8 Therefore, the main objective of this study is to investigate how different geometric and 9 traffic related variables affect the safety performance of motorways’ weaving sections, and 10 develop a quantitative model for crash prediction. A sample of 110 weaving sections 11 distributed all over the motorway network in The Netherlands was included. A database 12 composed of the traffic and geometric characteristics of the weaving sections, and of their 13 crash records was prepared. A Negative Binomial regression model was developed and the 14 factors that mostly influence the crash frequency at weaving sections were identified. 15 The results show that crash frequencies of weaving sections are significantly affected 16 by the length of the weaving section, the average annual daily traffic (AADT), the percentage 17 of weaving cars, the number of lanes on the main motorway and the location of the weaving 18 section relative to the interchange (if inside or outside the interchange). 19 20

Developing a Model for Estimating Weaving and Non-Weaving Speed within Highways Weaving Segments (Tehran)

In weaving section due to a strong need for lane changing, a type of turbulence is created in traffic flow; so, the speedand the capacity of the weaving section decreases. Therefore, investigation of the weaving section is very important.However, due to shortage of the manual for urban principal arterials (highways), calibration of these models is necessary.One of these models...

Priority Order for Improvement of Intersections using Pedestrian Crash Prediction Model

One of the most important needs of pedestrians is safety at crossing points, especially at intersections. Intersections are important parts of the urban road network because any disruption in them reduces the capacity of the entire network. The main objective of this research is to propose an appropriate method for prioritizing urban intersections with considering the important factors affectin...

Single-Vehicle Run-Off-Road Crash Prediction Model Associated with Pavement Characteristics

This study aims to evaluate the impact of pavement physical characteristics on the frequency of single-vehicle run-off-road (ROR) crashes in two-lane separated rural highways. In order to achieve this goal and to introduce the most accurate crash prediction model (CPM), authors have tried to develop generalized linear models, including the Poisson regression (PR), negative binomial regression (...
