Passenger Information Display System (PIDS) for buses

A Passenger Information Display System (PIDS) is an in-bus information display panel providing commuters with on-route information in real-time. These displays may combine audio announcements to complement the visual displays.

The Land Transport Authority (LTA) is responsible for bus procurement and their specifications since the start of the Bus Contracting Model (BCM). While several types of Passenger Information Display Systems have been trialled in the mid-2010s, the LTA made PIDS a mandatory requirement for future buses starting from 2018.

Past PIDS Units

Mobitec MobiSCREEN

Model Mobitec MobiSCREEN (LCD screen display)
Buses MAN A95 – Lion’s City DD (3-Door) Concept Bus (SG5999Z), MAN Lion’s City SD Concept Bus (SG4002G)

The Mobitec MobiSCREEN is a conventional LCD screen which displays real-time information on the next bus-stop along its route, and capable of supporting audio announcements. The system was activated on SG5999Z in end-March 2017 (several weeks after its launch) when the concept bus was trialled by Tower Transit on Bus Service 143, and scrolled through en-route bus stops.

Three identical units were installed around the bus: one on the lower deck (at the wheelchair bay) and two more on the upper deck (at the front of the bus, and at the rear staircase). A fourth unit on the lower deck (behind the rear staircase), which was present during public showcases in 2016, was removed to allow for more space in the confined seating area.

As of SBS Transit operations (April 2018), the PIDS is not in operation.

PIDS Features

  • Interior:
    – Next four bus stops
    – Bus Service Number
    – Current time

For SG4002G, the Mobitec MobiSCREEN PIDS display was never activated to display route details, and was stuck to displaying a static screen throughout the trial period.
