New city logistics approaches are needed to ensure efficient urban mobility for both people and goods. Usually, these are handled independently in dedicated networks. This paper considers conceptual and mathematical models in which people and parcels are handled in an integrated way by the same taxi network. From a city perspective, this system has a potential to alleviate urban congestion and ...

The convergence of multiple technologies has given rise to new types of information utilities called mobile location-based services. Specifically, the authors examine a context in which people need to move physically from one location to another via taxis. In this scenario, the user is in control of the location information associated with the mobile device. However, problems arise when a fleet...

We are exploring the enhancement of models of agent behaviour with more "human-like" decision making strategies than are presently available. Our motivation is to developed with a view to as the decision analysis and support for electric taxi company under the mission of energy saving and reduction of CO2, in particular car-pool and car-sharing management policies. In order to achieve the objec...

The increased amount of flights in airports has caused serious problems for passengers and airlines, and brings risks to the system of ground traffic. The sequencing of taxi management is responsible for coordinating the process of rolling the aircraft from gate to track, or conversely, depending on the procedure for takeoff or landing. In this paper, it presents an optimization solution of tax...

An initial model of human error in a real-world teamwork environment has been developed. The captain and first officer of a commercial aircraft and the air traffic controllers with whom they interact are modeled as the crew executes an approach and landing followed by taxi operations that take them to their assigned gate. Scenario details and human model development were based on the results of...

In cities that control the number of taxicabs by law or regulation, setting the number of cabs is one of the most important decisions made by taxicab regulators and elected officials. Licensing either too many or too few cabs can have serious deleterious effects on the availability and quality of service and the economic viability of the taxi business. Yet local officials often have difficulty ...

This study investigated pilots' taxi performance, situation awareness and workload while taxiing with three different head-up display (HUD) symbology formats: Command-guidance, Situation-guidance and Hybrid. Command-guidance symbology provided the pilot with required control inputs to maintain centerline position; Situation-guidance symbology provided conformal, scene-linked navigation informat...

The use of stated preference (SP) surveyed data of the motorcycle taxi riders in Bangkok and its vicinities has been investigated in this paper. A research aim is, preliminary, detailed in terms of the affect factors of the motorcycle between the internal combustion engine vehicle and the electric vehicle for public transport. With 1,200 surveyed data, the results show that 91.1% of the taxi ri...

Understanding urban population migration patterns is very helpful for urban operation and management, including the traffic forecasting, epidemic prevention, commercial resource allocation, emergency response and future urban planning. The large taxi fleet equipped with GPS comprises ubiquitous mobile probes in urban areas, and their trajectories reveal interesting phenomena in the city. We inv...

Is there a link between the color of a taxi and how many accidents it has? An analysis of 36 mo of detailed taxi, driver, and accident data (comprising millions of data points) from the largest taxi company in Singapore suggests that there is an explicit link. Yellow taxis had 6.1 fewer accidents per 1,000 taxis per month than blue taxis, a 9% reduction in accident probability. We rule out driv...
