The impact of changing bus services

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.

Passenger Counts – Analysis and visualization

Working as a subcontractor for Informi GIS Rapidis has helped Movia to implement a system which assists with the analysis and GIS-based visualization of a wide range of automatically collected transit-measurements such as passenger loads and service reliability. Rapidis developed the core database analysis component of the system. The system is an ArcGIS extension which behind the scenes executes queries based on request by users against an SQL Server & ArcSDE based data warehouse and presents the results in ArcMap in a style which is also user specified.

New OTM Trip Matrices

Rapidis was part of a consortium (with DTU Transport – Technical University of Denmark, TetraPlan A/S & Cowi) which carried out a project that aimed to establish updated and more accurate data for travel patterns in the Greater Copenhagen Area. These data are being used in assessment of the feasibility of building a new Metro ring-line in Copenhagen. The project was carried out using Traffic Analyst.

Movia

Working as consultant through Informi GIS Rapidis supplied a consultant, who has Implemented verification and recalculations modules in the VAU project (Vej og Adresse Udveksling – Road and Address Information Exchange).

US Urban Transit System

Brookings Institution – Analysis of US Urban Transit System.
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. The results of the project can be found here.

Potential travel demand

Rapidis has carried out an analysis for DSB Commercial, the marketing department of the Danish National Railways. The focus of the analysis was the identification of untapped potential travel demand in the main corridors of the rail network.

GIS interface for travel website

Working as consultant through Informi GIS Rapidis supplied a consultant, who has implemented an export module for linking spatial databases to the GIS-interface and timetable database for the Travel Planner Internet web-site (www.rejseplanen.dk).

Traffic Model Calculations

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.

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.

DSB S-Tog Department of Performance Monitoring

Updating Model for Simulation of 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.

Automatic Estimation of Passenger Travel Patterns

Rapidis partnered with Center for Traffic and Transport – Technical University of Denmark (now DTU Transport), to implement a system, which is used to produce detailed daily data describing S-Tog passengers travel patterns, based on data from counting and weighing systems installed in the trains. The system combines a detailed public transport route choice model with an advanced trip matrix estimation method.

Modeling Passenger Delays using a timetable-based assignment model

Rapidis, partnering with Center for Traffic and Transport – Technical University of Denmark (now DTU Transport), has developed a ground-breaking modeling system that is used to model the effects of train delays on the route choices of travelers using the Copenhagen Urban Rail (S-Tog). The system is also used to calculate the actual delays of passengers, that is, whether they actually arrived later than planned. The system is based on the Traffic Analyst Public Transport Assignment module.
