SICE is to exhibit its intelligent signalling system and LIDA devices at this year’s Intertraffic Amsterdam exhibition from 5-8 April.
Emergency signalling systems are vital for immediate tunnel evacuation and they make the difference between an incident and a tragedy. Normally, this kind of signalling has only reflective capabilities, lacking autonomous lighting. The message is always the same independently of the type of emergency, its position and its evolution.
There is more and more demand for a higher capability of functioning in degraded way to give response before emergency situations and lack of communication with the control centre. Therefore it is necessary to incorporate autonomous lighting capacities and fault tolerance design in wireless sensor network.
It is really important to adapt to the environmental circumstances and the incident evolution with the purpose of guiding the victim through the safest way at every moment, including functionalities which give support to the action of emergency response teams.
The objective is to design a new intelligent system for tunnels with an emergency-guided system and the capacity to function in a degraded way.This system has been developed by SICE in collaboration with University of Zaragoza and IMPLASER.
SICE will also be exhibiting its LIDA equipment at Intertraffic Amsterdam. LIDA DBT01" is an equipment designed to collect MACs from the Bluetooth devices, sending the collected data to the control centre via a communications network. Data from network LIDA devices are processed, and elaborate graphics and travel times information, per sections or pre-defined routes.
To elaborate travel times information or counting vehicles, only the Bluetooth devices ‘hands-free’ are considered, notwithstanding any ‘visible’ Bluetooth device is detected and classified.
There are two versions of the device: LIDA DBT01B has the possibility of being installed on lamposts as it has an electrical battery, designed to be fed by a power supply during, at least, 8 hours of charging and capable to withstand without power the rest of the day (more than 16 hours of discharge).
The second version is the LIDA DBT01e, which is designed to be installed over Variable Message Panels or any other signalling, continuous power supply. It has the functionality to show obtained travel times, in real-time, about aggregated data of 5, 10 or 15 minutes, as well as historical records for analysis. The devices are applicable for both urban and Interurban scopes.
The uncertainty margin about the estimated travel time data is also calculated as in the urban scope this variation can be significant, in short sections, affected by the own characteristics that traffic regulation implies.
This system has been developed by SICE in collaboration with UPM.
SICE will be showcasing its products at Stand 09.300 in Hall 9 of the RAI Amsterdam exhibition centre.
