The contractor administering the freeway electronic toll collection (ETC) system has passed a second week of evaluation, a performance review committee said late on Wednesday night.
Committee spokesperson Huang Tai-sheng (黃台生), a former National Chiao Tung University professor, said that the committee examined a total of 296,050 transactions recorded by freeway toll collection gantries between Feb. 6 and Feb. 11, but found only one erroneous transaction.
The error, which occurred on Feb. 7, was caused by Far Eastern Toll Collection Co (FETC) itself, when its personnel entered a wrong license plate number, Huang said.
Because of the error, the contractor failed to collect the toll fee from the responsible driver and charged another driver instead.
“This was an outrageous mistake,” Huang said. “We will ask FETC to explain to us how such an error would occur in the first place.”
Despite that mistake, the contractor’s performance met the standards that the committee set last month before the three-month evaluation period began.
The committee has stipulated that the occurrence of a stated error must not exceed 0.1 percent on a single toll collection gantry.
In addition to looking at the percentage of errors at a single gantry, the committee randomly selects six or seven gantries along the freeways each day during the evaluation.
The sampled gantries must not have this type of error at a rate of more than 0.02 percent per review period.
If the company fails to meet the committee’s standards, it will be penalized NT$500,000 per day.
The committee gave a passing grade to the contractor last week, when members of the committee found just two errors among the more than 350,000 transactions recorded from Feb. 1 to Feb. 4.
FETC’s eTag gantry system replaced freeway toll booths at the end of last year.
A new distance-based toll system took effect on Jan. 2, leading to complaints about overcharging.
