TrajAnalytics: A Free Software for Visually Exploring Urban Trajectories

Thanks to advanced technologies in sensing and computing, the mobility patterns and dynamics of urban cities and their citizen are recorded and manifested in a variety of urban trajectory datasets, which include the moving paths of human, taxi, bus, fleets, cars, and so on. Understanding and analyzing such large-scale, complex data is of great importance to enhance both human lives and urban environments. Supported by National Science Foundation, TrajAnalytics aims to provide exploratory data visualization tools for researchers, administrations, practitioners and general public to understand the data and to reveal knowledge intuitively.

Cloud Version:

TrajAnalytics is developed as a cloud-based software which can be accessed through Web browsers. It supports users to load raw trajectory data, and perform road based map matching and aggregation, as well as perform region based map matching and aggregation. The generated data tables, including Trajectory Data (TD Table), Trajectory Data on Streets (TDS Table), or Trajectory Data on Regions (TDR Table), are stored in TrajBase database on our cloud. A TrajVis visualization interface allows users to conduct extensive visual analysis at any time. Please read the TrajAnalytics guideline for details. You can start to use TrajAnalytics below. For accounts and other help, please contact us at

Data Loading

TrajAnalytics provides users with an independent data preprocessing software for users to load their own data to TrajAnalytics.

Road Map Matching

TrajAnalytics automatically fetch corresponding road segments data from OpenStreetMap and match the raw GPS data with road segments.

Region Map Matching

TrajAnalytics automatically match the raw GPS data with Zip code regions (USA Only) or Grid Regions.

Visualization System

TrajAnalytics provides easy to user Web interface for visually analyzing urban trajectory datasets. It allows users to interactively visualize and analyze trajectories over urban spaces.

Local Version:

TrajAnalytics is also provided as local version for users to work with the software on their own machines. Please download below and read the included guidance carefully.

  • Data Conversion Module: Please click HERE to download. Users can upload the raw trajectory data by the Data Conversion Module. It will then be converted to the TrajAnalytics data tables (Please read the TrajAnalytics guideline for more details), which can be used in the local TrajAnalytics below.
  • TrajAnalytics Package: Please click HERE to download the first version (V1). A complete guidance of installation is included in the package.
  • TrajAnalytics Package: Please click HERE to download the second version (V2).
