Additive measures of travel time variability

Engelson, Leonid; Fosgerau, Mogens - Volkswirtschaftliche Fakultät, … - 2011

This paper derives a measure of travel time variability for travellers equipped with scheduling preferences defined in terms of time-varying utility rates, and who choose departure time optimally. The corresponding value of travel time variability is a constant that depends only on preference...

Individual freight effects, capacity utilization, and Amtrak service quality

Krier, Betty; Liu, Chia-Mei; McNamara, Brian; Sharpe, Jerrod - In: Transportation Research Part A: Policy and Practice 64 (2014) C, pp. 163-175

This paper offers a new perspective on the post-deregulation rail industry. We hypothesize that a link exists between … individual freight effects and Amtrak service quality. Specifically, we investigate the relationship between freight control of … the infrastructure on which Amtrak trains operate and Amtrak train delays. Our sample consists of 1117 directional station …

Bhutan Transport 2040 Integrated Strategic Vision

Asian Development Bank; Asian Development Bank (ADB) - 2013

Bhutan, in 2040, will be very different from what it is today. The transport system then needs to respond to the changing needs and demands. The Transport Integrated Strategic Vision 2040 incorporates all existing transport related plans, policies, initiatives, and actions to create a long-term...

The Significance of Transport Costs in Africa

Naude, Wim; Matthee, Marianne - World Institute for Development Economic Research … - 2007

The success of Africa's exports, as well as its spatial development, depends on lowering transport costs. In this Policy Brief, we address a number of pertinent questions on transport costs in Africa, such as 'what are transport costs?', 'do transport costs matter for trade?', 'how important are...

Valuations of travel time variability in scheduling versus mean-variance models

Börjesson, Maria; Eliasson, Jonas; Franklin, Joel - CTS - Centre for Transport Studies Stockholm (KTH and VTI) - 2012

The standard method of estimating the value of travel time variability for use in policy appraisal is to estimate the parameters of a reduced-form utility function, where some measure of travel time variability (such as the standard deviation) is included. A problem with this approach is that...

How Full Is the tank? – Insights on Short-run Fuel Price Reactions from German Travel Diary Data

Ritter, Nolan; Schmidt, Christoph M.; Vance, Colin - 2013

We provide evidence that motorists respond to short-run fluctuations in fuel prices at the gas pump and not on the road. Employing variants of censored panel regression to control for unobserved heterogeneity and censoring of the dependent variable, we find that the fuel price has a large and...

Regional growth in Central Europe: Long-term effects of population and traffic structure

Polasek, Wolfgang; Berrer, Helmut - 2005

In a simple growth model we explore the current and future growth effects of the regional population structure. Regional GDP growth in 227 regions within six countries in central Europe is explored as how they depend on the young and old dependency ratio. The young dependency ratio (YDR) is...

Incorporating transportation network structure in spatial econometric models of commodity flows

LeSage, James P.; Polasek, Wolfgang - 2006

We introduce a regression-based gravity model for commodity flows between 35 regions in Austria. We incorporate information regarding the highway network into the spatial connectivity structure of the spatial autoregressive econometric model. We find that our approach produces improved model fit...

Traffic accessibility and the effect on firms and population in 99 Austrian regions

Polasek, Wolfgang; Schwarzbauer, Wolfgang - 2006

In this paper we describe the EAR (regional economic accessibility) model to investigate the impact of the improvement of railroad infrastructure on regional GDP, population and firms growth in 99 Austrian regions. We evaluate the impact of four potential railroad infrastructure investment...
