Protection system for level crossings by geospatial analysis in real time
1 like572 views
The document outlines a project aimed at enhancing warning systems for drivers approaching level crossings to reduce accidents. It describes the types of level crossings, the design of a real-time geolocation system that notifies drivers and infrastructure managers, and details the technology and data providers used. The system is currently operational with over 24,000 onboard devices and aims to improve accuracy and expand integration with car manufacturers and infrastructure managers in the future.

- 3. Outline Problem definition Types of LC Distribution of accidents in LC Focus on warning Goals System design LC application Data providers Used tools Final operational system Future
- 4. Problem definition The goal is to solve the problem of warning to drivers in advance to take precautions when they are approaching a level crossing Avoid accidents due to the occupancy level crossing for vehicles that have been stopped on the railroad
- 5. CLASS A Protected level crossings exclusively with fixed signals. CLASS B Protected level crossings with light and acoustic signals. (S.L.A). CLASS C Protected level crossings with half-barriers, double half-barriers or barriers, Automatic or Nailed (S.B.E., S.B.A. or S.B.E./S.B.A.). CLASS D Protected level crossings in Luggage Regime (Chains or Barriers or manual half-barriers). CLASS E Protected level crossings daycare walk Paso. CLASS F Step by exclusive level or Pedestrian and Livestock. Types of LC protection

- 7. Focus on warning Most effective is replace LC, but it is expensive, so • Signaling its location on the road by traffic signals in a passive way. • Closing by detecting the proximity of a train by an active way.
- 8. Goals Notify drivers a nearby Level Crossing. Notify to Infrastructure Managers about the interception of a Level Crossing by a vehicle when the driver indicates incidents. Notify to Infrastructure Managers about the interception of the track, at any point, by a vehicle when the driver indicates incidents. Improve road and railways safety, reducing level crossing accident impact
- 9. System design Solution based on geolocation in real time of all parts of the system and notifications to drivers and infrastructure managers, not to replace actual systems ● Level Crossing facilities, regardless of type. ● Vehicles. ● Trains. ● Infrastructure managers.
- 10. System design Taken advantage that connected car concept begins to take shape in all countries Collects real-time information Central intelligent cloud Returns information and events
- 11. System design Actual system developed for Dirección General de Tráfico collects real time information about: Position Speed Vehicle type Computes driver risk and return Real time audio an text notifications
