Interaction data and regional data  Travel time and travel cost matricesTravel time and travel cost matrices represent the travelled time or calculated generalised travel costs between sets of origins and destinations. Origins and destinations can represent any set of points of interest, such as cities, centroids of statistical entities such as NUTS regions or administrative regions, railway stations, inland ports or seaports, motorway intersections or motorway exits, airports, hospitals, universities, or any other set of point locations or network elements.
The travel time between all pairs of selected points of interest will be calculated over the network. The networks considered can be road or rail networks or waterway networks, or any combination of these three modes. Depending on the mode(s) chosen, and the purpose of the analysis, the travel time calculations can take into account different parameters such as different speed limits, slope gradients and slope penalties, congestion and agglomeration effects, local speed limits, statutory lorry driving resting periods, timetable travel times, waiting times at borders, waiting times at intermodal terminal points, cultural barriers and others. The particular set of parameters to be considered will be defined individually. It is possible either to calculate travel times between origins and destinations of the same type (e.g. between all pairs of capital cities), or between different elements (e.g. from all railway stations to all city centres).
Similar to the travel time matrices, the travel cost matrices are generated between all pairs of selected points of interest for different modes. Possible modes are cars and lorries, rail, inland shipping, and sea shipping, or any combination of these. Depending on the mode(s) chosen, and the purpose of the analysis, the travel cost calculations can take into account different parameters such as different cost functions, trip purposes and commodities, different speed limits, slope gradients and slope penalties, congestion and agglomeration effects, local speed limits, statutory lorry driving resting periods, timetable travel times, waiting times at borders, waiting times at intermodal terminal points, cultural barriers and others. The particular set of parameters to be considered will be defined individually. Time related parameters will be transferred into cost parameters by appropriate cost functions. Link or distance related cost parameter (e.g. fuel consumption) will be considered as well as general cost parameters (e.g. taxes). The cost functions can be specified individually. It is possible either to calculate travel costs between origins and destinations of the same type (e.g. between all pairs of capital cities), or between different elements (e.g. from all railway stations to all city centres).
The network database used for the travel time and travel costs calculations is the RRG GIS transEuropean network database.
