Smart cities are not merely the infusion of technology into a city’s infrastructure, but also require citizens interacting with their urban environment in a smart and informed manner. Transportation is key aspect of smart cities. In this paper, we present a smart route planning open-source system; SMART-GH utilizes open data and participatory sensing, where citizens actively participate in coll...

We describe an extension of the Markov decision process model in which a continuous time dimension is incllMcd in the stat(', space. This allows tbr the representation and exact solution of a wide range of prohleins in which transitions or rewards vary over time. We examine problems based on route planning with public transportation and telescope observation scheduling.

Algorithms for route planning in transportation networks have recently undergone a rapid development, leading to methods that are up to one million times faster than Dijkstra’s algorithm. We outline ideas, algorithms, implementations, and experimental methods behind this development. We also explain why the story is not over yet because dynamically changing networks, flexible objective function...

Distributed Learning Automata is automata based modelling approach for solving stochastic shortest path problems. The DLA can be applied to road networks to find shortest path that provides a spatial approach to bottom-up modelling of complex geographic systems that are comprised of infrastructure and human objects. Route finding is a popular Geographical Information System (GIS) application un...

The formulation, estimation, and validation of combined models for making detailed urban travel forecasts are described. These models combine origin-destination, mode, and auto route choices into a consistent forecasting method for multiple user classes for the Chicago Region. Household Travel Survey and Census Transportation Planning Package data for 1990, respectively, are used to estimate an...

A corridor is one of the new classes of airspace introduced with Next Generation Air Transportation System (NextGen). A well-designed corridor may reduce the airspace complexity, increase airspace capacity and decrease controller workload. This paper develops a computer simulation model for constructing risk-capacity tradeoff curves of en-route corridor concepts. Keywords-corridor; simulation, ...

One of the more interesting advances in transportation over the past decade is the introduction of intelligent transportation systems. Of particular interest is the flurry of activity directed at developing advanced traveler information systems (ATISs), especially systems that provide in-vehicle navigation assistance to drivers. These systems are designed to “acquire, analyze, communicate, and ...

In this study, a traffic management measure is presented by combining the route guidance of Advanced Traveler Information System (ATIS) and the continuous network design (CNDP) to alleviate increasing traffic congestion. The route guidance recommends the travelers to choose the shortest path based on marginal travel cost and user constraints. The problem is formulated into a bi-level programmin...

We use a conventional and straightforward route to fabricate scalable morphology-controlled regular structures. This route is based on the etching of PDMS microlens array in CF4 and CF4/O2 plasma. PDMS microlens array can be changed to regularly isolated microdot structures array in CF4 plasma. Microbowl shaped structures array can be reached in CF4/O2 plasma. Moreover, a set of structures afte...

Airborne dispersal of microalgae has largely been a blind spot in environmental biological studies because of their low concentration in the atmosphere and the technical limitations in investigating microalgae from air samples. Recent studies show that airborne microalgae can survive air transportation and interact with the environment, possibly influencing their deposition rates. This minirevi...
