Urban transportation systems are multimodal, sociotechnical systems; however, while their multimodal aspect has received extensive attention in recent literature on multiplex networks, their sociotechnical aspect has been largely neglected. We present the first study of an urban transportation system using multiplex network analysis and validated Origin-Destination travel demand, with Riyadh's ...

OpenTripPlanner was identified as the most promising open source multimodal trip planning software. OpenStreetMap, which provides mapping data to OpenTripPlanner, is one of the most well-known open source international repository of geographic data. General Transit Feed Specification, which provides transportation data to OpenTripPlanner, has been the standard for describing transit systems and...

Multitask emergency logistics planning is a complex optimization problem in practice. When disaster occurs, relief materials or rescue teams should be dispatched to destinations as soon possible. In nutshell, the can described an of multipoint-to-multipoint transportation delivery given multimodal traffic network. this study, network considered for planning, and mixed-integer programming (MIP) ...

Various disasters with serious results are reported and happen around our lives. Most of them are unconventional contingency events. Emergency relief is an important activity dealing with the disasters to transfer a large number of materials to the destroyed places for casualties and reconstruction for the country, even the world. Container multimodal transportation will play an important role ...

This paper describes a multimodal transportation network (MTN) in which several unimodal networks (AGVs, hoists, lifts, suspended monorail systems, etc.) interact each other via common shared workstations as to provide a variety of demand-responsive workpiece transportation/handling services. The set of transport modes provides connection support for production flows treated as agents trying to...

We designed a system to infer the multimodal itineraries traveled by a user from a combination of smartphone sensor data (e.g., GPS, Wi-Fi, inertial sensors), personal information, and knowledge of the transport network topology (e.g., maps, transportation timetables). The system operates with a Multimodal Transport Network that captures the set of admissible multimodal itineraries, i.e., paths...

This paper presents an alternative approach for time-dependent multimodal transport problem. We describe a new graph structure to abstract multimodal networks, called transfer graph, which adapts to the distributed nature of real information sources of transportation networks. A decomposition of the Shortest Path Problem in transfer graph is proposed to optimize the computation time. This appro...
