On-line calibration of behavior parameters for behavior-consistent route guidance
Paz, Alexander; Peeta, Srinivas - 2009
This paper calibrates on-line the parameters of a controller-estimated driver behavior model used in a deployable behavior-consistent approach for real-time route guidance by checking the consistency between the time-dependent actual and estimated system states. The behavior model has a fuzzy...

Multivariate traffic forecasting technique using cell transmission model and SARIMA model
Szeto, WY; Ghosh, B; Basu, B; O'Mahony, M - 2009
The paper develops a short-term space-time traffic flow forecasting strategy integrating the empirical-based seasonal autoregressive integrated moving average (SARIMA) time-series forecasting technique with the theoretical-based first-order macroscopic traffic flow model-cell transmission model....

Scaling properties of financial time series
Schreier, David - 2007
This thesis will first criticize standard financial theory. The focus will be on return distributions, efficient market hypothesis and the independence of returns. Part two gives the intuition to look at markets in a different view. Namely the one proposed by B. Mandelbrot who has shown that...

The effects of transportation costs on international trade
Skiba, Alexandre - 2003
This study investigates the effects of the transportation cost on the international trade. The first essay explores the … effect of the transportation cost on the quality composition of trade. We derive a relationship between per unit and ad … shipping costs and negatively with tariffs. These results provide a clear rejection of the iceberg assumption on transportation …

On the cost structure, efficiency and productivity of mass transit systems
Karlaftis, Matthew Georgios - 1996
The purpose of the present study was to investigate the cost and production structure of mass transit systems using both panel and time series data. Accepting cost minimization (subject to a set of constraints that reflect demand, regulatory, and urban setting conditions) as the economic...

Human decision-making and seat belt use
Calisir, Fethi - 1996
The methodologies used by researchers to analyze drivers' behavior have changed dramatically over the years. Several driver-behavior models focusing mainly on motivational and cognitive aspects of driving have been developed to identify major factors causing drivers to behave in unsafe manners....

Essays on firm responses to price volatility and international specialization
Schaur, Georg - 2007
Chapter 1 of this thesis examines in theory and empirics how exporters use different modes of transportation to hedge … price uncertainty. Ocean transportation in international trade imposes a time lag between the departure and arrival of a … expensive transportation hedges this uncertainty. Fast air shipments allow a firm to wait until the uncertainty is revealed …
