1 Taxi is certainly the most popular type of on-demand transportation service in urban areas because taxi 2 dispatching systems offer more and better services in terms of shorter wait times and travel convenience. 3 However, a shortage of taxicabs has always been critical in many urban contexts especially during peak 4 hours and taxi has great potential to maximize its efficiency by employing s...

the passenger line planning is a process of strategic long-term decision-making problem in the field of railway passenger planning. a line is a route between starting point and destination with certain stops, which has a certain frequency of train schedule. a new solution based on decomposition algorithm has been proposed in this paper, which is defined in a master problem and two sub problems....

Delay management for public transport consists of deciding whether vehicles should wait for delayed transferring passengers, with the objective of minimizing the overall passenger discomfort. We model the underlying transportation network as a directed acyclic graph, where edges represent trains, and weighted paths represent passenger flows. Given initial delays of some of the passenger paths, ...

Public transportation systems across the United States serve millions of riders every day, forming crucial links between people and their daily destinations. In this work, we develop a method for modeling public transportation systems as network graphs. We use the resultant graphs to study the properties of 18 public transportation systems from cities and counties in the United States and Canad...

Short-term passenger flow forecasting is an important component of transportation systems. The forecasting result can be applied to support transportation system operation and management such as operation planning and revenue management. In this paper, a divide-and-conquer method based on neural network and origin-destination (OD) matrix estimation is developed to forecast the short-term passen...

Ride-share systems, which aim to bring together travelers with similar itineraries and time schedules, may provide significant societal and environmental benefits by reducing the number of cars used for personal travel and improving the utilization of available seat capacity. Effective and efficient optimization technology that matches drivers and riders in real-time is one of the necessary com...

As a sustainable transportation mode, high-speed railway (HSR) has become an efficient way to meet the huge travel demand. However, due to the high acquisition and maintenance cost, it is impossible to build enough infrastructure and purchase enough train-sets. Great efforts are required to improve the transport capability of HSR. The utilization efficiency of train-sets (carrying tools of HSR)...

Prioritization is an increasingly important concept for transportation system planning and programming. The resources for capital improvements to state and regional transportation systems are stagnant or declining. AT the same time, population growth, urban development patterns, and travel behaviors are increasing the demands placed on transportation systems. The number and range of interest gr...

INTRODUCTION Previous research has clearly shown that studying a curriculum related to science, technology, engineering, and math (STEM) has numerous positive effects on students. These effects include increased motivation to learn, trends of higher achievement, and positive attitudes toward school [1]. Also, studying STEM topics makes students better problem solvers, better innovators and inve...
