Analysis of US Urban Transit Systems
The Brookings Institution of Washington DC, is using Traffic Analyst to carry out detailed analyses on the quality and efficiency of the transit systems of more than 100 of the largest cities in the US. Rapidis has developed a module that automates import of transit data in the Google Transit Feed Specification format to Traffic Analyst, in order to facilitate the project.
DSB S-Tog Operations Reasearch Department
Forecasting the effects of the temporary closing of urban rail-lines due to maintenance work
Rapidis has assisted DSB S-Tog in evaluating and selecting suitable bus services as a substitute for railway links closed for maintenance. A number of proposed substitute bus services were evaluated using detailed traffic model calculations. Based on the model forecasts the least inconvenient substitute bus services were selected and further detailed forecasts were produced in order to assess the required capacity, i.e. the number of busses and departures necessary at different times of the day.
Automatic Optimization of Delivery Routes for Online Shop
Working with Informi GIS, Rapidis has delivered a server based planning system for InterVare. The planning system supports InterVare’s online grocery shop, automatically optimizing delivery routes for efficiency and timeliness.
Effects of Proposed Railway liberalization in the EU
As part of a larger consortium Rapidis has carried out a series of traffic forecast calculations using the European Trans-Tools model.

DSB S-Tog Traffic Planning Department
Updating and Expanding the Automatic Passenger Counting System
DSB S-Tog has recently expanded rail-services throughout the night hours on some days of the weeks. As part of this service expansion, Rapidis has assisted DSB S-Tog (Planning and Traffic department) in updating and expanding the Automatic Passenger counting System (APS). APS is used to produce detailed data describing daily travel patterns as well as overall amounts of travelers. New functionality was added to ensure that night time traffic was handled correctly.
Analysing the impact of changing bus services
Rapidis has carried out an analysis for Movia, the Copenhagen area Bus transit operator. The analysis examined how significant changes in the bus services in an area affected the travelers using the entire public transit network. The analysis included comparisons between model results produced using Traffic Analyst, with real-life traffic counts, in order to assess the validity of the models used.
DSB S-Tog Department of Performance Monitoring
Updating Model for Simulating Passenger Delays
In an earlier project Rapidis and DTU Transport designed and implemented a simulation model that has been used by DSB S-Tog to analyze how train delays and cancellations affect travelers. Rapidis has now helped DSB S-Tog to update the system, expanding functionality, moving to a new data model and adding a more accessible GIS-based user-interface.
Forbruger-Kontakt A/SS
Delivery Route Optimization system
Rapidis has delivered a new automatic route planning system to Forbruger-Kontakt. The system is used to optimize distribution routes for advertising mail, resulting in fewer and more efficient routes, as well as sharply lowering the time spent on planning.
The system produces detailed routes based on a GIS road network and address data. In order to handle large areas the system automatically groups addresses into larger segments before starting the optimization calculations.
This lowers the calculation time and makes it possible to handle large areas at a time, containing hundreds of routes
On the technical side, the system is based on the Rapidis Logistics Planner - a server application, offering:
-
A web-service based programming interface
-
Job-queue functionality and multiple concurrent calculations
-
Efficient calculations utilizing multi-core CPU architectures for greater performance.
The server architecture makes it possible to easily handle multiple users requiring concurrent calculations.

European Union, TEN Connect project
Evaluation of TEN policy proposals using the TRANS-TOOLS transportation model
The European Commission has initiated a study of the future development of the European transport infrastructure. The study focuses on the effects of the TEN (Trans-European transport-Networks) policy, and is carried out using the transport model TRANS-TOOLS (which covers all of Europe), developed in a prior project. The transport model is based on ArcGIS from ESRI and the ArcGIS extension Traffic Analyst from Rapidis.
The European Commission is expected to produce a report in 2010 on the progress of the 30 priority transport axes of the TEN policy. The TEN Connect project will provide the analytical basis for this report and contribute to the analysis of economic, environmental and social impacts of a number of alternative policy options related to the development of the TEN policy.
The TEN Connect project is carried out by a consortium of companies and universities, headed up by the Danish engineering company TetraPlan. Rapidis is responsible for all software design and implementation.
