Training sequences for road speed prediction on a selection of roads in Prague

Training sequences for 1 hour road speed prediction training on a selection of roads in Prague retrieved from IT4I traffic simulator.
First 4 columns define road identifiers, for which a timeline of speed information is provided in the next columns.
5th column marks the time of a day (in the range 0 to 24), which is associated with a sample as a reference time stamp.
Next 16 columns represent 4 timeline sequences for the 4 concerned roads over past 1 hour (vx@ represents 15min back,vx@@ 30min back, etc).
Last 4 columns represent timeline sequence of an output road referring to the 1  hour future (vx+ mark represents 15min forward, vx++ 30min forward, etc.)

Speed value -1 means the information for a particular time instance for a particular road is missing.
