Information extraction from social media for route planning
Micro-blogging is an emerging form of communication and became very popular in recent years. Micro-blogging services allow users to publish updates as short text messages that are broadcast to the followers of users in real-time. Twitter is currently the most popular micro-blogging service. It is a rich and real-time information source and a good way to discover interesting content or to follow recent developments. Additionally, the updates published on Twitter public timeline can be retrieved through their API. A significant amount of traffic information exists on Twitter platform. Twitter users tweet when they are in traffic about accidents, road closures or road construction. With this in mind, this paper presents a system that extracts traffic information from Twitter to be used in route planning. Route planning is of increasing importance as societies try to reduce their energy consumption. Furthermore, route planning is concerned with two types of constraints: stable, such as distance between two points and temporary such as weather conditions, traffic jams or road construction. Our system attempt to extract these temporary constraints from Twitter. We train Naive bayes, Maxent and SVM classifiers to filter non relevant traffic. We then apply NER on traffic tweets to extract locations, highwaysand directions. These extracted locations are then geocoded and used in route planning to avoid routes with traffic jams
International overview on the legal framework for highly automated vehicles
The evolution of Autonomous and automated technologies during the last decades has been
constant and maintained. All of us can remember an old film, in which they shown us a
driverless car, and we thought it was just an unreal object born of filmmakers imagination.
However, nowadays Highly Automated Vehicles are a reality, even not in our daily lives.
Hardly a day we donât have news about Tesla launching a new model or Google showing the
new features of their autonomous car. But donât have to travel far away from our borders.
Here in Europe we also can find different companies trying, with more or less success
depending on with, not to be lagged behind in this race.
But today their biggest problem is not only the liability of their innovative technology, but also
the legal framework for Highly Automated Vehicles. As a quick summary, in only a few
countries they have testing licenses, which not allow them to freely drive, and to the contrary
most nearly ban their use. The next milestone in autonomous driving is to build and
homogeneous, safe and global legal framework.
With this in mind, this paper presents an international overview on the legal framework for
Highly Automated Vehicles. We also present de different issues that such technologies have
to face to and which they have to overcome in the next years to be a real and daily
technology
