Jakarta. Jakarta Police Chief Inspector General Tito Karnavian will summon the heads of smartphone-based motorcycle taxis, known locally as ojek, over traffic violations committed by drivers.

He expects to meet with the bosses of GoJek, Blu-Jek and GrabBike in the coming week.

The businesses must conform to legal regulations for driver behavior before expanding further, Tito said. Drivers commonly wait curbside for customers, contributing to further traffic congestion.

App-based ojek services have grown quickly in Indonesia since Go-Jek debuted in January, followed by GrabBike and Blu-Jek.

The services, available across the Greater Jakarta Area, have been embraced by Jakartans keen to avoid the city's notorious traffic.
