| Summary: | Air traffic demand is growing rapidly and is expected to continue growing in the future
due to an increase in global population, higher standard of living and advancement in
technology. This increased will present an ever more complex operating environment
for both aircraft and Air Traffic Controller (ATCO) as air traffic congestion posed a
severe risk to the safe transit of flight. It also increases ATCO’s workload
tremendously, making one of the most stressful job even more demanding.
It is foreseen that the current collision detection systems such as Short-Term Conflict
Alert (STCA) and Traffic Collision Avoidance System (TCAS) will not be sufficient
in addressing the future demand of air traffic. At such more sophisticated systems and
metrics are needed to address the issue of identifying potential conflict in an
increasingly congested and complicated airspace. One of the solutions currently under
researched is through the integration of colour to provide visual cue to assist ATCO in
identifying imminent danger. Past research studies have discovered that colours indeed
have the capability to guide attention effectively without experiencing tunnelling
effect.
This project aims to investigate if the integration of Colour Alert will help ATCO in
identifying potential collision faster in a simulated congested airspace. ATCOs’
response time will be used as the monitoring performance metric for this study.
It was found that there were distinct differences in conflict detection response time
when visual Colour Alert was used against no alert under two different air traffic
density condition. Results in this study have shown significant improvement in
response time between No Alert and Colour Alert scenario under high air traffic
density. |
