Consistent anticipatory route guidance
Anticipatory route guidance consists of messages, based on traffic network forecasts, that assist drivers' path choice decisions. Guidance is consistent when the forecasts on which it is based are verified after drivers react to it. This thesis addresses the formulation and development of solution …

Hybrid vehicle-centric route guidance
This thesis proposes a hybrid route guidance system in which predictive guidance is generated in a centralized layer and revised in a reactive, decentralized layer that resides on-board the vehicle. This hybrid approach is intended to improve guidance quality by balancing the ability of the …

Assessment of impact of dynamic route guidance through variable message signs
… congestion through the dissemination of dynamic route guidance to drivers. Variable Message Signs (VMS), installed on freeways, are used for incident management and provide information about the incidents and diversion routes. VMS can prove to be a significant tool used by the Traffic Management …

Dynamic travel time models for pricing and route guidance : a fluid dynamics approach
… How long does it take a driver to traverse a route in a transportation network? How long does a unit of product remain in inventory before being sold? As a result, our goal is not only to develop models for travel times as they arise in a variety of dynamically evolving environments, but also …

An adaptive strategy for providing dynamic route guidance under non-recurrent traffic congestion
… It is generally anticipated that Dynamic Route Guidance Systems (DRGS) will play an important role in reducing urban traffic congestion and improving traffic flows and safety. One of the most critical issues in designing these systems is in the development of optimal routing strategies …

Development of novel haptic tools for virtual navigation
… Fields for Global Haptic Sensing Applied to Route Guidance: Attractive force fields were studied in the context of providing route guidance. Several haptic guides were designed and evaluated in a developmental experiment. The most promising haptic guide was selected and compared to …

Decision support system for locating traffic information dissemination sites along freeway corridors
Dynamic route guidance systems which are products of the Intelligent Transportation Systems (ITS) Technology have been reasonably useful in guiding motorists from their origins to destinations. In general, transportation networks could be used more efficiently if dynamic route guidance information …

Investigations into effectively moving people and goods
… In the first part of this thesis, we focus on route guidance for the movement of people while in the second part we focus on the movement of goods by investigating the two main aspects of service network design: flow and resource planning. In Chapter 2, we introduce a centralized proactive route …

Simulation-based evaluation of Advanced Traveler Information Services (ATIS)
… main results are that the provision of dynamic route guidance can simultaneously benefit the individual performance of drivers, both guided and unguided, as well as the system performance of existing transportation infrastructure. In order to perform this analysis, it was necessary to develop a …

Scalability of dynamic traffic assignment
… predictions of network status and generate route guidance for travelers. The computational performance of such systems is a critical concern. Existing methodologies, which have limited capabilities for online large-scale applications, use single-processor configurations that are less …

Information provision in rating systems and traffic systems
… sets of users in a traffic network (e.g., due to route guidance systems) impact the traffic equilibrium, and show the conditions under which even those with access to additional information may suffer greater congestion. To this regard, we first introduce a new class of congestion games in which …

A framework for dynamic traffic diversion during non-recurrent congestion: models and algorithms
… the traffic flow, generating feasible alternate routes in real-time, and controlling traffic in order to achieve a pre-set goal based on a system optimal or a user equilibrium concept is required. In this dissertation, a framework that would satisfy these requirements is adopted consisting of a …

Utilizing A Real Life Data Warehouse To Develop Freeway Travel Time Eliability Stochastic Models
… imperative for providing travelers with accurate route guidance information. It can be applied to generate the shortest path (or alternative paths) connecting the origins and destinations especially under conditions of varying demands and limited capacities. The measurement of transportation …
