The Expressway Authority of Thailand (Exat) assured customers today that erroneous 'Easy Pass' balance displays that sometimes appear on tollways' electronic screens are not affecting he users' actual balance.
The Authority said that many customers had sent complaints saying their balances had been mistakenly deducted or altered when they passed through the tollgate.
A spokesman for the Authority said drivers made around 700,000 trips through electronic tolling booths a day, exceeding the limit for the current electronic tolling system to run efficiently which was set at about 500,000 trips daily.
The agency has revamped the system so that it could handle millions of trips each day and the upgrade is to be completed by six months, the official added.
He said that after the tolling system is improved, the agency will also reduce the wait time for an Easy Pass user to work after a top up, from 15 minutes to 4 hours to less than 15 minutes.
There are currently 264 electronic tolling booths and around 700,000 Easy Pass holders, the Bangkok Post reported.
