D-ATC indicator used on the E233 series trains. The digital ATC system uses the track circuits to detect the presence of a train in the section and then transmits digital data from wayside equipment to the train on the track circuit numbers, the number of clear sections (track circuits) to the next train ahead, and the platform that the train will arrive at.
Lack of a second speed limit below signal speed indicates ACSES is not in service. Advanced Civil Speed Enforcement System (ACSES) is a positive train control cab signaling system developed by Alstom. [1] The system is designed to prevent train-to-train collisions, protect against overspeed, and protect work crews with
Failure Reporting (FR). The failures and the faults related to a system, a piece of equipment, a piece of software or a process are formally reported through a standard form (Defect Report, Failure Report). Analysis (A). Perform analysis in order to identify the root cause of failure. Corrective Actions (CA).
VMS systems were deployed at least as early as the 1950s on the New Jersey Turnpike. [3] The road's signs of that period, and up to around 2012, were capable of displaying a few messages in neon, all oriented around warning drivers to slow down: "REDUCE SPEED", followed by a warning of either construction, accident, congestion, ice, snow, or fog at a certain distance ahead.

The 9K38 Igla (Russian: Игла́, "needle", NATO reporting name SA-18 Grouse) is a Soviet/Russian man-portable infrared homing surface-to-air missile (SAM) system. A simplified, earlier version is known as the 9K310 Igla-1 (NATO: SA-16 Gimlet), and the latest variant is the 9K338 Igla-S (SA-24 Grinch).
The empirical assured clear distance ahead calculated with computer vision, range finding, traction control, and GIS, such as by properly programming computer hardware used in autonomous cars, can be recorded to later produce or color baseline ACDA and safe speed maps for accident investigation, traffic engineering, and show disparities between ...
ISA was born in France when Saad and Malaterre (1982) carried out their study of driver behaviour with an in-car speed limiter. Actually, they did not really test Intelligent Speed Adaptation, because the system did not automatically set the correct speed limit; instead drivers had to set the limiter themselves, and, rather like a cruise control, they could set it as they chose.
Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...
