RTA gets global recognition for noise pollution measures
Dubai’s Roads and Transport Authority (RTA) has been accredited by a recent specialized benchmarking study accredited for the superior performance in ensuring that the daily operation of the Dubai Metro complies with the standard noise and vibration levels. Such findings were made in a study that covered multiple metro systems of metropolitan cities in the second half of 2020.
Abdul Muhsen Ibrahim Younus, CEO of Rail Agency, RTA, expressed his delight with this important technical achievement. “This achievement is a testament to the daily operational efficiency of the metro system as well as the safety and security levels of the metro service. The RTA prioritizes these two elements and endeavors to achieve them with distinction,” Younes said.
“The study focused on identifying the challenges confronting metro operators as regards the noise and vibration generated by the metro operation, measuring the level of noise and vibrations and analyzing the underlying reasons and associated factors. The study also tackled legislation and policies implemented in cosmopolitan cities, procedures for measuring and monitoring, and the technical solutions taken to mitigate the negative impacts of noise and vibration on the community,” he explained.
The study confirmed the superiority of the Dubai Metro in comparison with other global metro systems in terms of reduced noise and vibration, thanks to the daily operation and maintenance of the rail tracks. These findings are credited to the preventive measures taken by the Rail Agency in several aspects relating to the suppression of noise and vibration of the metro.
The study made several key findings such as the Dubai Metro is in a group of 10 metro systems (out of 27 covered by the study) that uses effective Key Performance Indicators to measure noise and vibration levels. The RTA was unique in having a technical manual for noise and vibration for rail systems.
The study ranked Dubai Metro amongst the best in tackling issues related to vibrations resulting from the metro operation and maintenance. Such treatment measures are highlighted by the rail grinding program. It was amongst the few metros that has a robust brakes inspection system as brakes are the key cause of noise levels. It was also amongst the top in receiving the least number of annual complaints relating to noise and vibration levels. Additionally, Dubai Metro was in the Top 11 metro systems that maintain monthly inspections relating to wheel re-profiling.
