Geographic Info Toolbox

The Geographic Info Toolbox is an extension of the Geometric Operations Toolbox and is used to evaluate and enrich dynamic driving data and trajectories with geographic context and information from maps or equivalent information sources with spatial data.

The toolbox can thus be used for the evaluation and analysis of data from traffic sensors, traffic observations, vehicle measurements, floating car data and other fleet data as well as the analysis of geographic data with temporal changes.

  • Purpose
  • Features
  • Architecture

The Geographic Info Toolbox is used for driving data and trajectories of

  • Naturalistic Driving/Riding data,
  • traffic measurements and recording of the dynamic behaviour of road users,
  • fleet data (FCD, FOT, etc),
  • tracking data (from fitness trackers, any GPS tracks,...),
  • vehicle sensors

and make it accessible for the evaluation and application of extended, multivariate statistics, machine learning, data mining, pattern recognition and other AI based methods.

That way exemplary applciations of the Geographic Info Toolbox are:

  • comprehensive post-processing of traffic simulations
  • quality assurance, evaluation and analysis of naturalistic driving & riding data
  • quality assurance, evaluation, fusion and processing of traffic measurements from different sensor data sources
  • analysis of context-sensitive driver behavior
  • topological investigations of the road network with time-varying properties
  • calculation of static and time-varying properties and features from maps and georeferenced trajectories.
  • plotting and graphical analysis of naturalistic driving/riding data
  • Core entities
    • specializations of the core entities from the Geometric Operations Toolbox, such as
      • various driving trajectories,
      • different types of roads,
      • traffic lights and other transport infrastructure,
      • road markings, zebra crossings,
      • road signs,
      • road types such as bridges or roundabouts, etc.
  • Core functionalities
    • reading/import of different map data and graphs, either
      • offline (GIP, simulation software) or
      • online (e.g. OpenStreetMap)
    • selection of elements from the road network (bridges, roundabouts, road types, ...)
    • functions for preprocessing naturalistic driving/riding data
    • calculation of trajectory features
    • localization and error compensation of naturalistic driving/riding data
    • visualization of maps and trajectories

The Geographic Info Toolbox is an extension of the

It cannot operate without these two. As consequence als MATLAB is necessary for the Geographic Info Toolbox.

If you want to perform scenario-based developments including traffic simulations or naturalistic driving/riding data, then the Geographic Info Toolbox can be seamlessly integrated into the Stipulator.

For quality assurance of traffic simulations or any other traffic data, the Geographic Info Toolbox can be seamlessly integrated into the Expectator.

Optionally, functions of the

from Mathworks are used for further speedups and functionalities.
