Beyond Big Data – FAST DATA in Transport

Beyond Big Data is Fast Data. It captures the idea of analysing fast-moving connections from which we can make better decisions to maximise insights.
Big Data is largely about two things:
1) Lots of data and 2) Data located in a non-relational database without much structure from which you can gain insights.
Think about Piccadilly Circus in London or Times Square in New York: The one thing they have in common is fast movements from pedestrian to vehicles, and lots of it. Beyond Big Data is Fast Data. It captures the idea of analysing fast-moving connections from which we can make better decisions to maximize insights.
Most of the focus on Big Data so far has been in transportation situations where the data which is being managed is basically fixed—it has already been collected and stored in a Big Data database.
This is where Fast Data comes in. Fast Data leverage Big Data sources and it adds a real-time component of being able to take action on real-time traffic events and information before they even enter a Big Data system. In the transportation world, Fast Data means faster decisions and faster reactions. Its applications are far reaching from real-time traffic management to faster than the real-time traffic forecasts. Fast data is the backbone of coordinated vehicle to vehicle and vehicle to street information system for the next generation transport (e.g. autonomous vehicle operations, evacuation planning/disaster management, road safety etc.) and infrastructure (e.g. smart street, adapted street lighting, smart homes, future cities etc.) planning.
From a technology point of view, Fast Data is now feasible and fully practical for transport applications with the availability of cheaper parallel computing facilities (e.g. Amazon cloud computing, etc.) and new database management tools for Fast data (no SQL, Hadoop etc.). Various Local Authorities in the UK are now looking for Fast Data application in their traffic management and future transport planning.
