Air traffic flow management (ATFM) is an important component in an air traffic control system and has significant effects on the safety and efficiency of air transportation. In this paper, we propose a distributed ATFM strategy to minimize the airport departure and arrival schedule deviations. The scheduling problem is formulated based on an en-route air traffic system model consisting of air routes,...
Dementia, Autism, and Alzheimer's disorders affect millions of people worldwide. Suffering from forgetfulness, affected patients tend to wander off and potentially get into dangerous situations. This work develops the Alzimio mobile app, to provide safety functions to these patients; including safe-zone geofencing, activity-based alarms, take-me-home, navigate to nearest friend, and check-on-me. Six...
To provide a basis to quantitate the navigational risk and evaluate the traffic safety for maritime safety administration to control the traffic as soon as possible to assure the traffic safety, this paper referred to the study on conflict delay time of road traffic and the application of traffic conflict technique used in waterway traffic, we try to analyze the influencing factors of navigational...
This paper presents a model of vessel traffic scheduling on a fairway as a factor increasing traffic safety. The methods in use are usually used for job shop scheduling issues. Problems of this type can be represented as disjunctive graphs — proposed herein is graphical representation of selected individual traffic scheduling problems. Unlike tasks performed by machines, in navigation the problem...
Emergency service vehicles need safety and fluent paths to save time. In this paper, a centralized traffic control mechanism is proposed for the evacuation of vehicles that drive toward the dedicated path of the emergency vehicles (EV), e.g. ambulance, fire engines, police cars, etc, using the dedicated short range communications (DSRC) protocol. In our proposed mechanism, a centralized server is...
