(cont.) by presenting two case studies both in the context of the Chicago Transit Authority. One study proposes an enhanced method of inferring the rail trip OD matrix from an origin-only AFC system to replace the routine passenger survey. The proposed algorithm takes advantage of the pattern of...

(cont.) academics, researchers, and practitioners interested in improving transportation and air quality in the region. The survey shows that there is hesitation in considering any such policy in the MCMA without prior improvements in public transport. In light of these findings, we have...

This research identifies the challenges Chicagoland must confront to maintain a quality transit system. It analyzes the organizational and funding structure of the Regional Transportation Authority and its three service providers, including the Chicago Transit Authority. This investigation...

The feedback based integrated assessment model ANEMI represents the society-biosphereclimate- economy-energy system of the earth and biosphere. The development of ANEMI model is done using the system dynamics simulation approach that (a) allows understanding and modeling of complex global change...

In flood frequency analysis, a flood event is mainly characterized by peak flow, volume and duration. These three variables or characteristics of flood are random in nature and mutually correlated. In this article, a methodology is developed to derive bivariate joint distributions of the flood...

The accuracy and quality of river forecasts are dependent on the nature of each flood. Less extreme , more common, floods may afford deviations between the predicted forecast and observed stage because the locals may be prepared, based on past experience to deal with the less extreme flood...

This study represents a review of existing flood response, exploration into potential improvements, and possible enhancement technologies. Research includes gathering information from individuals associated with response, searching for and testing emergent technologies, and gauging interest in...

Three chemical fate models (SLSA, TOXIC and EXAMS II) were applied to a flood control/recreational reservoir in Iowa to assess the long-term fate of a persistent chemical, dieldrin. These models were validated via calibration, verification and sensitivity analysis based on 16 years of field data...

Many claim that, with regard to transportation infrastructure, only partnerships between public and private entities, which draw on the strengths of both, can achieve the goals of enhancing operational efficiency, increasing service delivery, improving asset maintenance, and stretching scarce...

Microbial risk assessment (MRA) is a process that evaluates the likelihood of adverse human health effects following exposure to a medium in which pathogens are present. Several different classes of models are available to quantitatively characterize risks to human health from exposure to...
