Evaluating public transit modal shift dynamics in response to bikesharing: a tale of two U.S. cities
Public bikesharing—the shared use of a bicycle fleet—has recently emerged in major North American cities. Bikesharing has been found to decrease driving and increase bicycling. But shifts in public transit have been mixed. The authors evaluate survey data from two U.S. cities to explore who is shifting toward and away from public transit as a result of bikesharing. The authors explore this ques...
To determine the preliminary effectiveness of breast cancer screening among Chinese females, 1226714 women aged 35-69 years first received clinical breast examinations. Urban women with suspected cancer received mammography followed by breast ultrasound (BUS), while rural suspected women underwent BUS followed by mammography. After one-year follow-up, 223 and 431 breast cancers were detected am...
Cities comprise various functional zones, including residential, educational, commercial zones, etc. It is important for urban planners to identify different functional zones and understand their spatial structure within the city in order to make better urban plans. In this research, we used 77976010 bus smart card records of Beijing City in one week in April 2008 and converted them into two-di...
This study contributes to the literature on mobility and wellbeing at older ages through an empirical exploration of the meanings of free bus travel for older citizens, addressing the meanings this holds for older people in urban settings, which have been under-researched. Taking London as a case study, where older citizens have free access to a relatively extensive public transport network thr...

Saha Roy Power system state estimation with exclusive utilization of synchronous phasor measurements demands that the system should be completely observable through PMUs only. To have minimum number of PMUs, the PMU placement issue in an...
Noc architecture performs better comparing to bus based when the number of processors is small. On the other hand bus based performs better than noc when number of the processors is large. This leads to new architecture which is hybrid bus based architecture where each node is packet switched in a mesh network of noc architecture that contains bus based system with small number of processors. F...
The high contribution of greenhouse gas (GHG) emissions by the transportation sector calls for the development of emission reduction efforts. In this paper, we examine how efficient bus transit networks can contribute to these reduction measures. Utilizing continuum approximation methods and a case study in Barcelona, we show that efforts to decrease the costs of a transit system can lead to GH...
An Improved Bus Signal Priority System for Networks with Nearside Bus Stops. (December 2004) Wonho Kim, B.S., Chungbuk National University; M.C.P., Seoul National University Co-Chairs of Advisory Committee: Dr. Laurence R. Rilett Dr. Amy Epps Martin Bus Signal Priority (BSP), which has been deployed in many cities around the world, is a traffic signal enhancement strategy that facilitates effic...
In this paper, we present models and the corresponding decision-support tool, SARTRE, for evaluating the Public Transport Networks (PTN), and more specifically a bus network. Firstly, we define the framework architecture of SARTRE. The PTN model is explained, and various evaluation and assessment methods are explained. These models and evaluation algorithms are specifically designed to address ...
introduction the urban population experienced rapid growth in the recent decades, particularly between 1975 and 2000 when it has reached from 1.5 to more than 2 billion people. by turn of the century; half of the world's populations are concentrated in cities. this would severely affect the quality of life in urban areas. accordingly, cities will be faced with significant challenges in inf...
