We introduce a stochastic discrete automaton model to simulate freeway traffic. Monte-Carlo simulations of the model show a transition from laminar traffic flow to start-stopwaves with increasing vehicle density, as is observed in real freeway traffic. For special cases analytical results can be obtained.

This paper presents improved time-dependent control strategies for small freeway networks with bottlenecks and unique origin-destination paths. It is assumed that there are no spill-overs from any of the freeway exits so that freeway queues and delays can be completely avoided by regulating access to the system so as to maintain bottleneck °ows strictly below capacity. It is also assumed that t...

Currently most optimization methods for urban transport networks (i) are suited for networks with simplified dynamics that are far from real-sized networks or (ii) apply decentralized control, which is not appropriate for heterogeneously loaded networks or (iii) investigate good-quality solutions through micro-simulation models and scenario analysis, which make the problem intractable in real t...

Traffic conflicts between merging and through vehicles are typical phenomena near freeway on-ramp sections, yet few microscopic models describing the interaction of these vehicles in the merging process have been proposed. In this paper, vehicle interactions during merging process are modeled under an enhanced game-theoretic framework. Freeway on-coming through vehicle and on-ramp merging vehic...

Original scientific paper This paper adopted chi-square test and binary logistic regression to analyse factors about mountainous freeway crash severity level in the southeast of China and to determine the factor impact on crash severity level to make corresponding measures to improve road safety. Results of this paper indicated that younger and older drivers, female drivers, weekends and drivin...

This report develops a probabilistic model for analyzing longitudinal collision/safety between an abruptly decelerating vehicle and its immediate follower on an Automated Highway System. The input parameters are the distance between the two vehicles, their common speed prior to the failure, the reaction delay of the following vehicle and a bivariate distribution for the two deceleration rates. ...

This study seeks to find a strategy capture the most observed trajectories with minimum number of algorithms. GPS information on 4,538 real trips from 131 travelers in 2008 was collected and analyzed Minneapolis-St. Paul (the Twin Cities) as part I-35W Bridge Collapse study. The high-resolution road network Cities includes 108,561 nodes 277,747 links. Labeling link penalty approaches are combin...

The purpose of this study is to assess the relation between the speaking space of the /s/ sound and the freeway space in two subject groups. One group had natural dentition (Group I, n = 61) and the other comprised complete denture wearers (Group II, n = 33). The analysis was done by means of a jaw-tracking device (K6-I Diagnostic System, Myotronics Research Inc., Seattle, WA, USA). Freeway spa...

The choice of investment strategy has a great impact on the performance of transport infrastructure. Positive projects such as the "Subway plus Property" model in Hong Kong have created sustainable financial profits for the public transport projects. Owing to a series of public debt and other constraints, public-private partnership (PPP) was introduced as an innovative investment model to addre...
