1. Physics and Semantics A passenger boards a fast train. It takes her some distance, reverses course, and returns to the starting platform. She reports that according to her clock, the trip took n seconds. An observer who remained behind on the platform gets a different reading. Using his clock, he records a longer time interval m. These claims are compatible with the clocks being in perfect o...

The return trip often seems shorter than the outward trip even when the distance and actual time are identical. To date, studies on the return trip effect have failed to confirm its existence in a situation that is ecologically valid in terms of environment and duration. In addition, physiological influences as part of fundamental timing mechanisms in daily activities have not been investigated...

This paper describes the development of railway station choice models suitable for defining probabilistic station catchments for use in the aggregate demand models typically used to forecast demand for new rail stations. Revealed preference passenger survey data obtained from the Welsh and Scottish Governments was used for model calibration. Techniques were developed to identify trip origins an...

Paratransit plays an important role in the urban passenger transportation system in the developing countries. Three cities viz. Imphal East, Imphal West and Silchar in India have been undertaken for the study. Household survey and traffic survey have been employed to collect data for the paratransit users. Modelling techniques and tools also have been used to forecast the utility of paratransit...

The traditional four-step model has been widely used in travel demand forecasting by considering trip generation, trip distribution, modal split and traffic assignment sequentially in a fixed order. However, this sequential approach suffers from the inconsistency among the level-of-service and flow values in each step of the procedure. In the last two decades, this problem has been addressed by...

New York City taxi rides form the core of traffic in city York. The many taken every day by Yorkers busy can give us a great idea times, road blockages, and so on. Predicting duration trip is very important since user would always like to know precisely how much time it require him travel from one place another. Given rising popularity app-based usage through common vendors Ola Uber, competitiv...

Mortality data of disabled individuals are studied and parametric modeling approaches for the force of mortality are discussed. Empirical observations show that the duration since disablement has a strong effect on mortality rates. In order to incorporate duration effects, different generalizations of the Lee–Carter model are proposed. For each proposed model, uniqueness properties and fitting ...
