An interactive network data management software which makes it possible to overlay a given travel demand on top of an existing or planned traffic network, covering a wide range of application areas, including network design, network analysis and network variant assessment.

Allows the creation of trip matrices and, specifically, the calculation of travel demand matrices within a given planning area, based on such parameters as behavioural population group membership and activity chains. Trip generation, trip distribution and travel assignment are performed using a disaggregated activity chain model.

Software for various application areas, such as the detailed modelling of traffic flows at major intersections and on road networks, the simulation of all traffic, including motorized vehicles and pedestrians crossing the roads in the given area, the determination of traffic- and signal control-related parameters, the calculation of emissions, and the 2D and 3D visualization of vehicle movements within the network.

A software suite consisting of three modules: Project-SIGNPOSTS for the automated design of traffic signs of all types, including exact sizing in compliance with the relevant traffic signs regulations; Project-ROADWORKS for the creation of roadworks safety plans; and Project-ROADMARKINGS for the design of road surface markings in compliance with the German road marking regulations.

A CAD software for various areas of application, including the simulation of road designs in site maps, contour maps and cross-section maps; interactive graphics-based design of alignments in site maps; the creation of digital terrain models; interactive graphics-based simulation of vertical alignments, including mass balancing; the development of cross-section road profiles, including the automated generation of fill, sidehill cut and through cut slopes. The DXF interface allows the direct import of geodetic data provided by a land surveyor’s office.

A software for even more efficient and productive design and drafting. Optimized AutoCAD tools enable the user to perform routine tasks more quickly and accurately.

Vehicle manoeuvre and swept path and turn simulation software that assists users in the design of facilities for both stationary and moving traffic, such as intersections, roundabouts, bus terminals, loading bays and other projects. In addition, AutoTurn allows users to calculate and display vehicle manoeuvres, even without a given spline curve.

This software is particularly well-suited for integrated planning projects which cover a wide variety of engineering fields, from terrain modelling and mapping to road and canal network planning to accounting. The modular design of RZI Tiefbau allows planners and earthworks engineers to adapt the software to their specific project requirements.

A traffic engineering software for the planning and management of traffic light systems, using state-of-the-art methods for the development of traffic light control systems and the evaluation and coordination of signal time plans. Such plans can then be visualized and traffic-dependent control signal systems can be tested in simulated scenarios.

The calculation of road traffic noise is based on two parameters: noise emission and noise exposure. In calculating noise emissions, a distinction is made between point, linear and area sources of sound, taking a variety of factors into consideration, including the influence of distances, the diffraction of sound around obstacles, air and soil absorption, and the influence of weather and reflection.

Software for the management of tender contract operations and accounting of construction works, which also features an ASTRA interface and national standard road and bridge construction specifications.
