We define an infrastructure restriction as any event in the infrastructure that makes decrease the number of circulations that can pass through a point or section, or impose a speed reduction. These restrictions are caused by works, incidences, speed limits, and it can be temporary or permanent.
To carry out efficient management of operations, it's important to anticipate the effects of these restrictions and to know how the trains and other type of circulations are affected. This affectation may by speed reductions or even elimination of its circulation and it introduces an additional cost in the operation of Railway or Road Companies.
Right now calculations to quantify the impact of these restrictions are based on relational databases, or even hierarchical, and they use only alphanumeric attributes. They do not take into account the geometry of the lines on which the restriction occurs and is not considered the micro-level topology.
In other studies, we have demonstrated the use of INSPIRE and RINF regulations, with RailTopomodel topological models as a means to model a valid topology for the European railway network.
This paper describes a method to use the topological basis described above both to create routes by rail and road from scheduled circulations from a spatiotemporal point of view. A temporary component within the coordinate Z has been added to the traditional route with longitude and latitude coordinates (X, Y), to define a TrainRailwayLink feature. This allows us to perform geospatial analysis including time as a key variable.
As a result, the set of circulations affected by the restrictions and the lost time is computed. This results in an economic cost. Computations are made in real time and can be run in batch mode for further statistical analysis.
With this knowledge we can compute the most costly restrictions both for railway and road companies or even the Infrastructure Manager can take them into account to solve those efficiently.
