Transit network conditions change everyday. While those changes should be considered for modifying a transit network, formulating and optimizing the whole transit network may be a costly, difficult task. This article uses a developed transit network design model to examine how optimal transit networks should be developed based on changes in input elements of the transit network. Three major inp...

In-transit inventory financing is gaining popularity as an alternative way to access financing. However, compared with other means such trade credit and bank loans, the effects on supply chain of a third-party logistics provider (TPL) providing in-transit are seldom investigated. This study adopts channel competition model examine impact chain. Through comparative analysis conventional approach...

introduction: treatment in chronic constipation is highly dependent on colon transit time (ctt), which not only determines the cause but also determines the correct treatment policy. the aim of this study was evaluation of ctt in constipated patients. methods: 43 patients with chronic constipation who did not respond to high fiber diet were enrolled in the study. patients with history of drug i...

morphine was used as a remedy for the control of diarrhea centuries before it's sedative-analgesic effect was discovered. although several mechanisms have been proposed for the morphine-induced inhibition of gastrointestinal transit (oit), the exact mechanism has not yet been identified. on this basis the possible involvement of the dopaminergic system in morphine-induced inhibition of tra...

Objective- In this study, the general anatomical features of the digestive tube and the transit time of the digestive tube of the Zarudni’s spur-thighed tortoises were examined by contrast radiology. Design - Experimental study. Animals - 4 adult female Zarudni’s Spur-thighed Tortoises (Testudo graeca zarudnyi). Procedures- At a temperature of 25-27°c a set of dorsoventral rad...

This paper focuses on the railway rolling stock circulation problem in rapid transit networks, in which frequencies are high and distances are relatively short. Although the distances are not very large, service times are high due to the large number of intermediate stops required to allow proper passenger flow. The main complicating issue is the fact that the available capacity at depot statio...

This study examines the intersection of race, family structure, and economic inequality through women’s spatial relationships to the labor market. Using survey data from three major metro labor markets, we operationalize spatial relationships in two ways: first, using a conventional measure of commute time, and second, using an indicator of neighborhood job contacts to obtain employment. Result...

This paper explores the weather-ridership relationship and its potential applications in transit operations and planning. Using the Chicago Transit Authority (CTA) as a case, the paper investigates the impact of five weather elements (temperature, rain, snow, wind, and fog) on daily bus and rail ridership, and its variation across modes, day types, and seasons. The resulting relationships are a...
