Only 55 percent of taxis with the Bermuda Taxi Association are using GPS systems during peak Airport times.

The Transport Control Department reviewed taxi data, provided by BTA, in order to address recent concerns about service to the Airport.

The data revealed that of the 334 subscribers to the BTA GPS system only 183 taxis were using it.

"This number is at first glance, concerning, and so we are drilling down the data to ascertain just what is happening during these crucial periods," TCD director Randy Brangman said.

"I am not convinced that just 185 taxis were operating at this time but take this as an indication of taxis engaged in other work like tours and private transportation."

Mr. Brangman urged subscribers to all computer dispatch companies on the Island to use their GPS systems.

"Having invested the equipment, it really makes no sense not to use it," he added.

"For the sake of efficiency and good service I urge operators to turn their systems on."

His comments were echoed by BTA president Michael Ray who said drivers should take the opportunity to cash in on booming cruise season business.

He said: "We are encouraging drivers to utilise their GPS ? the minute you turn it on you are making yourself available. It promises to be a busy season."

It was important to show that taxis could move the public otherwise Government would continue to look for other options, said Mr. Ray.

"There were four new minibuses coming line in the last few months. Government feels, and I don't agree, that we need to utilise more means of transport."

He added: "Let's get out our vehicles, let's work our vehicles. Let's use GPS, it does work."

Another area that TCD looked into was pre-arranged Airport limousines.

Mr. Brangman confirmed some companies were operating "well below" their seat capacity and he has set up a meeting with these businesses to address it.

"We understand this reduced seat capacity with Airport limousines is adding to the unavailability of taxis at the Airport," he said.

"With the Ministry's wider mandate of providing a quality experience for our guests from start to finish, I have undertaken to address this issue as a matter of urgency."

Mr. Brangman also said TCD would sanction the suspension or loss of permits if the situation was not urgently remedied.
