A new transport service with a focus on passenger safety is set to rival Perth's taxi and Uber drivers.

Shofer will launch 80 cars into the Perth market on Thursday, with the new on-demand service allowing passengers to book a ride using an app and agree to a pre-determined fare.

Shofer driver Rachel Giovannetti said the service provided several safety features its competitors lacked.

"For [female] riders, what they can do is go onto the app and select to have a female driver if they want ... so it's a great safety feature," she said.
