This article introduces a model for freeway traffic dynamics under stochastic capacity-reducing incidents, and provides insights for freeway incident management by analyzing long-time (stability) properties of the proposed model. Incidents on a multi-cell freeway are modeled by reduction in capacity at the affected freeway sections, which occur and clear according to a Markov chain. We develop ...

This work describes a micro simulation program that is developed to study freeway ramp merging phenomena under congested traffic conditions. First, the results of extensive macroscopic and microscopic studies are used to establish a model for the behaviour of merging drivers. A theoretical framework for modeling the ramp and freeway lag driver acceleration-deceleration behaviour is then present...

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...

Bottlenecks are key features of any freeway system. Their impacts are of increasing importance as congestion worsens in major urban areas. In the U.S., the FHWA has been working to identify and monitor key bottlenecks in each state. In Oregon, a freeway data archive known as PORTAL records count, occupancy, and speed measurements from over 600 freeway locations. This archive has enabled develop...

The paper begins with a brief discussion of issues that must be resolved in building a freeway data management system. Following this is a description of the design choices that dealt with these issues in a functioning system for California freeways. The system is called PeMS. Some concrete uses of PeMS are presented next. These uses imposed the functional requirements that led to the design ch...

Based on the stochastic concept for freeway capacity, the procedure of capacity estimation is developed. Due to the fact that it is impossible to observe the value of the capacity and to obtain the probability distribution of the capacity, the product-limit method is used in this paper to estimate the capacity. In order to implement estimation of capacity using this technology, the lifetime tab...
