The Centre of Excellence for Testing and Research of Autonomous Vehicles-Nanyang Technology University (Cetran) has tested and approved over 50 autonomous vehicles (AV)  for operation in Singapore. The vehicles approved include driverless taxis, shuttles, buses and road sweepers.

Some AVs also have specific functions such as last-mile delivery of food and equipment, as well as surveillance. Other vehicles include an on-demand AV taxi trial by NuTonomy and Grab as well as on-demand 10- and 26-seater bus services by ST Engineering, SBS Transit and SMRT Corporation Limited (SMRT) at Science Park II and Jurong Island. More trials, including buses, are already being planned by the agency.

The Government and Nanyang Technology University (NTU) established the Cetran testing agency to assess the viability of deploying AVs in Singapore as well as to certify the vehicles as safe and capable enough to be tested on roadways.
