Alexander Dennis Ltd. Enviro500 concept bus.

Alexander Dennis Ltd.’s (ADL) Enviro500 full low-floor, three-door, two-staircase double-deck bus was on display at the LTA-UITP Singapore International Transport Congress and Exhibition (SITCE) in Suntec City, Singapore October from 19 to 21, 2016.

The Enviro500 concept bus, commissioned by the Land Transport Authority (LTA), is the result of close collaboration between the transport agency and ADL. Exhibited at a series of Bus Carnivals at venues across Singapore in March and April 2016, visitors were encouraged to provide their feedback on the design of this brand new vehicle designed specifically for Singapore. Positive feedback on the design and specification has also been received from international visitors to this week’s SITCE event, according to company officials.

The concept bus retains many of the features which have made ADL’s Enviro500 the most popular high-capacity double deck bus in the world. The most significant difference is the third door and second staircase. The second and third doors act as the exit points for all riders, the result being an efficient, two-stream passenger flow throughout the vehicle which speeds up boarding and alighting, reduces vehicle dwell time at bus stops, and enhances the passenger experience. Ease of access for all passengers is guaranteed due to the absence of any internal steps in the lower saloon. 

The bus has a range of sophisticated onboard specifications including luxurious high-back contoured seating, Wi-Fi, USB charging points at all seats, mood lighting, and passenger information screens. Improvements for the driver include a comfortable, ergonomically designed seat within the spacious cab area. A large curved windscreen offers excellent visibility, and a CCTV monitor gives the driver all round clear views of staircases and exit doors for the added security of passengers.

“The LTA challenged ADL to design and build a double deck bus with three doors and two staircases which they believe will transform the passenger experience," said Paul Davies, director/GM of Alexander Dennis Asia Pacific. "A series of engineering workshops with the LTA, in addition to passenger feedback, has enabled us to further refine the initial design into a viable technical solution.”
