About this workspace

This workspace is a SAMRoute instance dedicated to the structural analysis of road–rail level crossings (LX) and nearby emitters of traffic-at-risk. It gives a portfolio-scale view of how access to sensitive sites depends on specific crossings. It provides a common quantitative frame for COMEX, operations teams and regulators.

1 What does it do?

For each level crossing (LX), SAMRoute screens the vicinity, looks for potential emitters of traffic-at-risk, identifies the potential destination targets around those crossings, and measures how dependent the emitter's escape routes are on each LX, which is what we qualify as LX functional dependency.

2 Which emitters are analysed?

This workspace concentrates on operationally sensitive emitters of traffic-at-risk like Seveso-type industrial sites, fuel depots, logistics hubs and distribution centres, as well as public-service sites such as schools and elderly care homes.

The exact list of emitters is defined with your organisation and can be extended to any other site types whose access you want to stress-test against nearby LX.

3 How to use it at portfolio-scale?

At portfolio scale, you screen all LX in your area and rank them by how strongly nearby emitters of traffic-at-risk depend on them.

The indicators highlight crossings where emitters are in a single-point-of-failure (SPOF) situation or where the detour would be prohibitive. They act as surrogate measures of fragility, so you do not have to wait for rare incidents to reveal weak points in the network.

4 How to use it at LX-scale?

For top-ranking LX, you can then deep-dive into their dependency profile by listing the emitters that rely on a given LX, comparing the baseline route that crosses the LX (h0) with the best alternative that avoids it (h1), and by reading the additional time, distance and manoeuvres involved.

This gives COMEX, operations teams and regulators a shared quantitative basis to prioritise studies, works and policy discussions on a focused subset of crossings rather than a flat portfolio.

5 What this LX workspace is? And what it's not?

The focus is on structural, portfolio-scale analysis and decision support, not on minute-by-minute navigation or signalling. It is provided as a demonstrator for evaluation; a production-grade, live-integrated deployment would be adjusted for your organisation.
