Toyota is resuming operations of its autonomous vehicles at the Paralympic Games village in Tokyo following an accident.
Services of the e-Palette pods were halted after a vehicle hit a visually impaired athlete last week.
The athlete was not seriously injured, but he had to pull out of an event because of cuts and bruises.
The vehicles will now have more operator control and extra staff to ensure they do not hit any more people.
Aramitsu Kitazono, a member of Japan’s judo team, was hit as he was walking across a pedestrian crossing on Thursday.
Mr Kitazono was unable to compete in his 81kg category because of the accident.
In a statement late on Monday, Toyota said: “The vehicle’s sensor detected the pedestrian crossing and activated the automatic brake, and the operator also activated the emergency brake. The vehicle and pedestrians, however, came into contact before it came to a complete halt.”
The company said that operators would now be given control over how fast the vehicles travel, with two members of safety staff on board, rather than one, to help look out for pedestrians.
New safety features will also include louder warning sounds, while pedestrian guides at busy crossings in the Paralympic village will be increased to 20 from six.
Toyota also said that it would continue to make safety improvements “on a daily basis” until the village closes.
The company also said it was co-operating with a local police investigation to determine the cause of the accident.
Chief executive’s apology
On Friday, Toyota chief executive Akio Toyoda made a public apology after the incident.
“A vehicle is stronger than a person, so I was obviously worried about how they were,” he said in a YouTube video.
Mr Toyoda said the accident illustrated just how difficult it was to operate self-driving vehicles in the special circumstances of the village during the Paralympics, with people there who are visually impaired or have other disabilities.
“It shows that autonomous vehicles are not yet realistic for normal roads,” he added.
