Customized buses (CBs) are a new mode of public transportation and an important part of diversified public transportation, providing advanced, attractive and user-led service. The operational activity of a CB is planned by aggregating space-time demand and similar passenger travel demands. Based on an analysis of domestic and international research and the current development of CBs in China an...

The purpose of the Air Transportation System (ATS) is to provide safe and efficient transportation of passengers and cargo. The on-time performance of the ATS is measured by flight-based metrics such as flight delays and flight cancellations. Researchers have shown that flight-based metrics do not accurately reflect the passenger trip experience, and especially underestimate the impacts of canc...

The goal of this paper is to demonstrate the use of an innovative social media-based data source, Twitter, to evaluate transit rider satisfaction. Transit authorities have access to vast amounts of performance metrics that measure ridership, timeliness, efficiency, safety, cleanliness, and service, to name a few. These performance metrics, however, are generally one-sided; they represent the in...

The expanding global air network provides rapid and wide-reaching connections accelerating both domestic and international travel. To understand human movement patterns on the network and their socioeconomic, environmental and epidemiological implications, information on passenger flow is required. However, comprehensive data on global passenger flow remain difficult and expensive to obtain, pr...

Mobility-as-a-service systems are becoming increasingly important in the context of smart cities, with challenges arising for public agencies to obtain data from private operators. Only limited mobility typically provided city agencies, which not enough support their decision-making. This study proposed an entropy-maximizing gravity model predict origin–destination patterns both passenger and f...

Abstract. Accurate traffic data are the basis for group control of elevators and its performance evaluation by trace driven simulation. The present practice estimates a time series of inter-floor passenger traffic based on commonly available elevator sensor data. The method demands that the sensor data be transformed into sets of passenger input-output data which are consistent in the sense tha...

Prior to the attack on the USS Cole and the events of 11 September 2001, the U.S. Navy was developing antiterrorism programs to address potential terrorist attacks in a resource-constrained environment. Amid unprecedented tragedy associated with these and other terrorist strikes against U.S. interests, both domestic and abroad, government agencies, the Armed Forces, and private companies have r...

This paper examines linkages among transportation intensity, the extent of urbanization, CO2 emissions, and economic growth. We use two measures of transportation intensity: (i) per-capita rates of utilization of air-passenger transport facilities and (ii) per-capita rates of utilization of air-freight transport facilities. By studying the G-20 countries over the period 1961e2012 and employing ...
