Colour-coded e-pass to limit passengers in Kol metro

September 07, 2020 15:49

A colour-coded e-pass system using a mobile phone has been developed by a technology solutions company here for ensuring that a maximum of 400 passengers board a Metro Railway train in the city to maintain Covid-19 health safety protocol after it resumes service.

Sanjay Chatterjee, network and security solutions head of Ideation Technology, which was asked by the Metro authorities to develop the system, said that a bot-based (web robot) technology will be used to generate e-passes that will be colour-coded to ensure that only authorised passengers enter the stations at a given time in order to maintain the maximum passenger count.

"The main challenge was to come up with a solution which can be easily used by people - those who have smartphones and also those who have analogue phones; without installing any app," he told PTI.

"So we came up with a simple technology, we have developed a system similar to that of Whatsapp or Facebook Messenger, wherein one can start it by just clicking open a link," Chatterjee said.

He said that a bot is being used for the purpose wherein it will ask the intending passenger his or her name, the boarding station, destination and the preferred time slot. A passenger will be given a total of five questions, including one on language option, which he has to answer using the link in the mobile phone. Chatterjee said that the passengers will have three language options - Bengali, Hindi and English.

"The Metro authorities have told us that a maximum of 400 passengers can be carried in a train at any point of time, based on that either the chosen time slot will be given and if the number of passengers has already reached the threshold, a different time slot will be asked for from the intending passenger," he said, adding that the process will not take more than 10 to 12 seconds. -- PTI
