Abstract

Urban transit has traditionally been conceived and governed within a paradigm of regulation and government ownership. This study explains how the alternative paradigm of property rights, which works so well in other sectors of the economy, can apply to urban transit. The key to a property rights framework is defining the building-block properties of the system. The study explains why the essential properties for the case of fixed-route urban transit are curbspaces, or bus stops, at which a scheduled service can secure for itself the passenger congregations generated by its investments. The study proposes a system of curb fights, including exclusive curb zones leased by auction and owned like property, and common curb zones where freewheeling jitney services can pick-up passengers. The study also offers property-rights interpretations of diverse transit experiences, and proposes privatization and deregulation for all forms of transit.

Abstract

This paper describes the process and the results of the evaluation of Traffic Congestion Manager (TCM), a knowledge-based system for Traffic Management Center operator assistance in real-time congestion management. The process of evaluation included the validation of the correctness of the underlying knowledge base and the assessment of the system’s performance, through the definition of several simulation-based scenarios. The results demonstrate the ability of the system to effectively reduce driver travel time and stop time in the network under congested conditions, through the implementation of real-time traveler information and signal control. The results also provide insights into some of the weaknesses of the TCM approach, that will be addressed to fine-tune its reasoning capabilities and improve its performance.

A web-based evaluation framework for supporting effective air quality improvement policies

Abstract

This study presents a web-based air quality evaluation framework that enables the analysis of changes in local emissions and the corresponding predicted impacts on public health. The framework includes emission models, air dispersion models, and a health impact analysis methodology based on the comprehensive air quality index suggested by the Ministry of Environment in South Korea. The primary feature of this framework is its flexibility and its ability to distinguish between macroscopic and microscopic standpoints, depending on the goal of the analysis. In general, emissions can be estimated from nationwide data provided by the National Clean Air Policy Support System or by integrated traffic simulation and emission models to calculate the amount of pollutants emitted from traffic. Air dispersion can be estimated by examining specific dispersion models in accordance with the goal of the analysis. In addition, public health impacts can be predicted in relation to emissions concentration using the air quality index. This study demonstrates the effectiveness of the proposed framework using a case study examining alternative traffic operational strategies. As a result, the framework can be used for scientific evaluation and analysis of urban traffic planning, traffic management policies, and public agencies’ decision-making support for city center redevelopment.

Agent-based tour chaining model for advanced tourist information and scheduling systems

Abstract

Recent technologies make it possible to implement real-time tourist information and scheduling systems under ubiquitous information and computing environments. This study develops an agent-based simulation model to evaluate such plausible systems. The agent-based simulation model incorporates activity chaining behavior into tour activity scheduling systems. Individual tourist’s activity chaining behavior is formulated as a utility maximization problem. The underlying assumption of the model is that tourists increase their activities within their time and budget constraints to maximize their utilities. The model seeks individual’s optimal tour schedules by solving Prize-Collecting Multiple-Day Traveling Salesman Problem (PC-MD-TSP). The simulation model also includes real-time and end-of-day rescheduling capabilities by taking tourists’ unpredicted delays into consideration. Through experiments in an isolated tour island, this paper presents possible effects of tour information and scheduling systems.

Proposing new measures of employment deconcentration and spatial dispersion across metropolitan areas in the US

Abstract

A well-known challenge is measuring employment concentration across metropolitan areas and analysing the evolving spatial structure. We introduce a new approach that avoids identifying “job centres” and conceptualizes the distribution of employment based on two dimensions: (1) employment deconcentration; and (2) spatial dispersion of high employment locations. We apply this framework to study 329 US metropolitan regions based on 1 sq km. grid cells. We find diverse trajectories of metropolitan restructuring between 2000 and 2010, and substantial variation across regions in employment concentration. The new framework enables researchers to compare metropolitan regions to gain insights into the dynamic nature of metropolitan spatial structure.

Development of methodology to design advanced traffic surveillance systems for traffic information based an origin-destination

Abstract

The innovative feature of this study is first to develop a methodology for designing advanced traffic surveillance systems based on microscopic traffic simulations. The developed methodology makes it possible ultimately to obtain algorithm structures and associated parameter values. The methodology consists of two main simulation experiments. The first experiment includes a parametric evaluation based on Monte Carlo simulation to identify the required performance of the surveillance system. The second experiment involves performing a microscopic traffic simulation with actual surveillance algorithms and synthetic algorithm inputs. Paramics capable of adding various external modeling routines realized by advanced programming interfaces was used for both simulation experiments. As an application of the proposed methodology, an inductive signature-based anonymous vehicle tracking system was designed via origin-destination flow estimation problem. The outcomes of this study can serve as a logical and necessary precursor to field implementation of a variety of traffic surveillance systems.
