Anadelta Software Road and Highway Design Software

Anadelta Software is a Greek software development company with many years of experience in the road design software market. It was established in 1993 in the city of Xanthi, Greece, and currently maintains offices in Athens, Xanthi and Lamia.

Anadelta Software’s CAD platforms have been used in thousands of road infrastructure projects for almost two decades and have been established among Greek civil engineers as the ideal solutions for road design and construction.

Almost all Greek national roads, such as the Egnatia Motorway, the National Athens-Salonika Motorway or the Athens-Corinth-Patras Highway, have been constructed either in part or in their entirety with the help of Anadelta Tessera, Anadelta Software’s flagship highway design software.

Highway design and construction software

Anadelta Tessera is a multifunctional, highly configurable highway design and construction program. It offers a wide range of sophisticated features and capabilities, such as:

  • Full support for intersection and interchange design, as well as service roads
  • Automatic creation of composite cross sections at road junctions
  • Intuitive, visual construction of the road corridor with real-time feedback to the user
  • Rich library of typical cross sections, easily modified and expanded
  • Corridor rehabilitation
  • Road surface slope visualisation
  • Extensive visibility analysis (visibility distance, automatic side space expansion)
  • Mass Haul tables, Bruckner diagram calculation
  • Advanced terrain modeling and visualisation
  • 3D environment with editing capabilities
  • Easy production of 3D presentation videos of finished projects
  • Built-in scripting language
  • Complete, standalone development environment (does not require but can interoperate with external CAD software)

Advanced terrain modeling and processing subsystem

Tessera includes an advanced terrain triangulation and processing subsystem. Able to operate quickly and efficiently on models consisting of hundreds of thousands of points, it supports features such as breaklines, nested calculation boundaries, multiple TINs per project, exhaustive terrain consistency and validity analysis and repair, terrain layers, re-triangulation of selected areas only, volumetric operations, as well as extensive post-processing and visualisation capabilities.

Road layout and horizontal and vertical alignment

The initial road layout can be easily defined, either visually or by importing it from a text file. The software features a complete set of transition curves, such as clothoids, circles and parabolas, which can be freely combined to produce the actual corridor shape. The roadway surface is constantly recalculated and visible during the design stage, along with all information regarding bend geometry (such as radii, bisectors, circle centers, as well as starting and ending points for all curves).

In case of overlapping curves or invalid parameters, Tessera alters the shading on the problematic areas in order to alert the user. Service roads, auxiliary axes, traffic islands, widenings and user-defined corridor sidelines are readily supported. Multiple roads can be defined this way and combined to quickly and effortlessly form complicated intersections and interchanges.

The road profile can be easily modified by using the mouse, while the program displays helpful information such as slopes and height differences, co-depended road elevations and slopes at key points (very helpful for interchange design), as well as any specific geometric properties of the road at the current working position.

Cross section templates for road geometry

By taking advantage of the rich library of typical cross section templates included in the program, the user can quickly and accurately model the required road geometry. Even if an exact match is not found in the library, an existing typical cross section can be modified or a new one can be visually constructed from scratch. In either case, the new cross section can be added back to the library.

As with all other Tessera entities, cross sections are not just drawings, but live objects: editing a cross section, for example, will cause the program to recalculate all affected quantities.

Road design and construction in a 3D environment

Beyond merely displaying a rendering of the finished project, the built-in 3D environment is an invaluable tool for both inspecting as well as modifying the project throughout its production. It is from within this environment that the user can create 3D video files suitable for presentations, as well as export high resolution images of selected cross sections.
