server-based real-time localization of cleaning vehicles and personnel location overview including status information and movement history.

AT A GLANCE
• server-based real-time localization of cleaning vehicles and personnel
• location overview including status information and movement history

PROBLEM DEFINITION

Tunnels are subjected to intensive cleaning and technical testing at regular intervals. The cleaning of tunnel walls and floors with special vehicles reduces the risk of fire and considerably increases the brightness and thus the safety in the tunnel. However, the fact that the exact locations of vehicles and employees are unknown often prevents efficient tunnel cleaning. Delays in the cleaning process can result in longer traffic disruptions and total closures. If accidents or hazardous events occur during maintenance or cleaning work, it is often not possible to locate the cleaning personnel quickly, which can lead to life-threatening situations.

SOLUSION

Real-time localization of vehicles and employees leads to increased personal safety and minimized traffic disruption. With the help of a tracking system, it is possible to determine exactly where the individual cleaning vehicles are located and how many and which persons are in the respective work area. The management has access to the current locations and can continuously monitor and control all movements and status information of the vehicles (e.g. delays, downtimes, maintenance intervals).
