As part of a number of Intelligent Transportation (ITS) applications aimed at providing an environmental benefit, eco-approach technology is one that is feasible in the near-term. An eco-approach application uses Signal Phase and Timing (SPaT) and intersection map information of signalized intersections to provide drivers with recommendations in order to encourage “green” driving while approaching,...
Currently, there are many models available which can be used to describe a driver's behaviour for a traffic simulation. Despite the number of available formalisms it is our opinion that existing approaches neglect the interplay between the simulation topology and strategic decisions of simulated drivers. Existing models either disregard strategy updates or focus on short-term strategies only. In this...
This paper presents an overall concept and framework of a driver model with the intent to generate realistic traffic flow and motion while reflecting the nature of driving characteristics. The proposed driver model simulates a driver's driving on the road with proper trajectory planning mechanism that takes into account the surrounding environment, including lane and road geometry, surrounding obstacles,...
In this paper, we present a congestion-aware route planning system. First we learn the congestion model based on real data from a fleet of taxis and loop detectors. Using the learned street-level congestion model, we develop a congestion-aware traffic planning system that operates in one of two modes: (1) to achieve the social optimum with respect to travel time over all the drivers in the system...
Route planning is a core part of the traffic information system. Conventional route planning models rely heavily on an improved weighted shortest path algorithm, while this paper proposes a route planning methodology based on taxis' experienced travels. Taking advantage of the data from floating cars, the framework explores drivers' experience in route choices, extracts taxis' operating behaviors...
With the number of motor vehicles rapidly increasing, urban parking has become an intolerable problem in major cities in China. Parking facility service evaluations play an important role in urban transportation planning and operation. This paper introduces a level of service (LOS) concept based on a comprehensive parking study in Beijing, China. The LOS methodology developed by an integrated evaluation...
Evacuees' behaviors have a significant impact on evacuation efficiency. Evacuation clearance time is one of the key indicators in the evacuation planning and management. Evacuees' departure time choice, destination choice and route choice behavior based on real-time traffic information are three crucial factors used to estimate evacuation clearance time. In this paper, we use the orthogonal experimental...
Emergency disaster management has emerged as a vital tool to reduce the harm and alleviate the suffering the disasters can cause to their victims. A significant task of planners involved in the emergency disaster management is the ability to plan for and satisfy the vital needs of the people located in the emergency shelters, such as the Superdome shelter at New Orleans. As clearly stated by Whybark...
In this paper we revisit the following link observability problem: Determine the smallest subset of links in a traffic network for counting sensor installation, in such a way that it becomes possible to infer the flows on all remaining links. While a solution methodology has already been proposed in the literature, unfortunately, path enumeration was required which is infeasible for large-scale networks...
Metropolitan areas today have become more than ever saturated with various types and sources of real-time data. Yet, the unsolved practical challenge how to most effectively combine data sources currently prevents the wide use of this data as a powerful tool to both improve the quality of the transport supply and to influence travel demand. Focusing on London, this paper investigates the current state...
