HiWi Job “Movement Pattern Detection and Recognition” at the Institut für Kartographie und Geoinformatik


Job objective

The Institut für Kartographie und Geoinformatik (ikg) is looking for a motivated student to work on research/programming-related
activities under the topic “Movement Pattern Detection and Recognition”. The objective of this job will focus on the study of vehicle
trajectories that can reveal traffic regulations through the detection and recognition of common driving patterns (e.g. collocated events like stops,
slow movements, sequences of actions, etc). Some known algorithms (CB-SMoT, T-OPTICS, etc) for discovering important
places by detecting stops and movesalong objects’ movement trajectories are going to implemented and tested.Experiments
on parameter tuning of these clustering algorithms are also going to be undertaken in an application-driven way. Some
well-documented implementations of relevant algorithms written in Python are provided for familiarization with the topic.


Tasks and time schedule
  • Pre-processing of data: filter spatial trajectories to reduce measurement noise (outlier removal)
  • Algorithms’ implementation: implement known algorithms
    and modify them according to the application needs
  • Experiments and testing
  • Writing documentation

Data and Tools
  • Dataset: GPS Trajectories Data Set (an open dataset is provided)
  • Tools: PostgreSQL database with PostGIS extention (tutorial of installation and usage is provided)

Prerequisites
  • Programming: knowledge of a programming language as the tasks are heavily dependent on implementing algorithm
  • Data Analysis: prior experience in data analysis is
    desirable but not mandatory
  • Interest and willingness to work with movement data
    and explore moving objects’ behaviour
