Ridership is a key goal in the transit industry. Conventional transit analysis focuses on two types of users—captive and choice riders—but rarely aims to understand the preferences of non-transit riders. This research aims to better understand habits and preferences—for both users and non-users of the transit system—as they relate to the transit market in the Twin Cities metropolitan area. Our ...

today’s transportation is known as one of the most important elements of urban development structure. public transportation, according to its more extensive functional capacity, can play a vital role in wider scale. transit oriented development by focusing on the subways is one of the special approaches in this field. recently, tehran public transport fleet has significantly improved especially...

introduction: hydronephrosis is one of the major causes of referring infants for nuclear medicine investigation. renal dynamic study is the most reliable investigation for such children. however direct evaluation of renogram leads to generation of parameters that have no physiological interpretation. the configuration of renogram is very much dependent upon the rate at which radiopharmaceutical...

establishing a network of transit routes with satisfactory demand coverage is one of the main goals of transitagencies in moving towards a sustainable urban development. a primary concern in obtaining such anetwork is reducing operational costs. this paper deals with the problem of minimizing construction costsin a grid transportation network while satisfying a certain level of demand coverage....

background functional constipation (fc) and constipation-predominant irritable bowl syndrome (cibs)are two main subtypes of constipation that can be distinguished by the rome ii criteria. measuring colonic transit time (ctt) is an easy and cost effective way to evaluate constipation. this study was conducted to compare the ctt in patients with fc and cibs. materials and methods those patients w...

BACKGROUND Tracking an ingested magnet by the Magnet Tracking System MTS-1 (Motilis, Lausanne, Switzerland) is an easy and minimally-invasive method to assess gastrointestinal transit. The aim was to test the validity of MTS-1 for assessment of gastric transit time and small intestinal transit time, and to illustrate transit patterns detected by the system. METHODS A small magnet was ingested...

Intersections are considered as the most critical parts of the bus rapid transit (BRT) system. Transit signal priority is one of the efficient solutions to reduce BRT fleet delays at intersections. The aim of this study is to propose a new algorithm to decrease the BRT fleet delays at actuated intersections, while reducing the negative impacts on different approaches. The adaptive strategy is a...

INTRODUCTION Many factors alter gastrointestinal transit. Animal models are useful for preclinical studies of gastrointestinal transit, but terminal methods do not allow later study, and stressful assessment methods will likely alter the transit of the animal. To overcome these factors, we developed a new method to assay rat total gastrointestinal transit. METHODS Standard plastic cages with ...

BACKGROUND The esophagus has a different response in relation to the characteristics of a swallowed bolus. Bolus viscosity and body position may affect esophageal contraction and transit. Objectives To investigate the effect of bolus viscosity and body position on esophageal contraction, transit and perception. METHODS Esophageal contraction, transit and perception of transit were evaluated i...
