Travel time and speed estimation are part of many intelligent transportation applications. Existing approaches rely on either function fitting or data aggregation represent different tradeoffs between generalizability accuracy. Function-fitting learn functions that map feature vectors of, e.g., routes to travel estimates, which enables generalization unseen routes. However, mapping imperfect of...

In this paper we use the results of a recent on-site recreation survey to know whether it matters to use perceived rather than calculated travel costs. The calculated travel costs (time and money) are derived from detailed GIS computations. The perceived travel times and costs are taken directly from the survey responses. We first find that there is a high non-response rate for the perceived co...

rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. in the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. with traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. four s...

Travel time is an important measurement used to evaluate the extent of congestion within road networks. This paper presents a new method to estimate the travel time based on an evolving fuzzy neural inference system. The input variables in the system are traffic flow data (volume, occupancy, and speed) collected from loop detectors located at points both upstream and downstream of a given link,...

In the context of public transportation system, improving the service quality and robustness through minimizing the average passengers waiting time is a real challenge. This study provides robust stochastic programming models for train timetabling problem in urban rail transit systems. The objective is minimization of the weighted summation of the expected cost of passenger waiting time, its va...

Abstract Predictions of traffic volumes on road networks must be precise for transportation planning, and equilibrium trip assignment models based the Volume Delay Function (VDF) are typically employed. In 1964, U.S. Bureau Public Roads (BPR) created a VDF widely used in many countries, including Indonesia. However, using capacity manuals from Western nations Indonesia did not produce desired r...

This article argues that investigating the conceptual structure underlying the use of the pluperfect and the future perfect reveals a new complex type of nested dual mental time travel: mental time travel into posteriority embedded into mental time travel into “anteriority in the past” (underlying the pluperfect) versus mental time travel into posteriority embedded into mental time travel into ...

The collapse of geographical space over the last 200 years has had profound effects on the circulation of human populations and on the transfer of infectious diseases. Three examples are used to illustrate the process: (a) the impact of the switch from sail to steamships in importing measles into Fiji over a 40-year period; (b) changes in measles epidemic behaviour in Iceland over a 150-year pe...
