Methodologies for integrating traffic flow theory, ITS and evolving surveillance technologies
… is to develop methodologies for applying traffic flow theories to various ITS categories through the utilization of evolving surveillance technologies. This integration of theory, measurement and application has been overlooked since the advent of ITS because of the number of disciplines …

A System for Travel Time Estimation on Urban Freeways
… many advances have been made in the field of traffic engineering and ITS applications, there is a lack of practical travel time estimation procedures for ATIS applications. Automatic Vehicle Identification (AVI) and Geographic Information System (GPS) technologies can be used to directly …

Truck Modeling Along Grade Sections
This research effort first characterizes the trucks traveling along US highways by analyzing data from Interstate 81. It is hypothesized that I-81 is typical of US highways and thus can provide some insight into typical truck characteristics. These truck characteristics are important for the …

Assessing the Effect of Traffic Incident Management Areas on Highway Capacity
<p>Traffic Incident Management Areas (TIMAs) are established to facilitate emergency response and restore traffic flow following roadway incidents. However, lane closures within TIMAs significantly impact roadway capacity, requiring an analysis of capacity reduction across different closure …

Microscopic Modeling of Human and Automated Driving: Towards Traffic-Adaptive Cruise Control
… parts. The first part deals with a microscopic traffic flow theory. Models describing the individual acceleration, deceleration and lane-changing behavior are formulated and the emerging collective traffic dynamics are investigated by means of numerical simulations. The models and simulation …

Development and estimation of traffic data-based operational measures for effective winter snow management
Snow storms degenerate safety and traffic mobility by creating adverse driving conditions including visibility impairments, reducing pavement friction, obstructed road facilities. Improving the effectiveness of the snow management requires an efficient assessment of the operational strategies with …

Naturalistic Driving Data for the Analysis of Car-Following Models
The driver-specific data from a naturalistic driving study provides car-following events in real-world driving situations, while additionally providing a wealth of information about the participating drivers. Reducing a naturalistic database into finite car-following events requires significant …

Data-driven modeling and transportation data analytics
… transportation research. Unfortunately, existing traffic models, though developed and practiced for decades, are not data driven and therefore inherently incapable of analyzing modern traffic data from multiple sources with different time resolution and spatial coverage. A new paradigm centered on …

Towards a Comprehensive Bicycle Motion Behavior Model and Naturalistic Cycling Dataset
Most of the existing bicycle flow traffic research is limited to characterizing the longitudinal motion of bicyclists based on the assumption that there is no significant differences between the dynamics of a single-file bicycle traffic and the longitudinal motion behavior of cars. This research …
