ADL improves visibility with cameras in place of mirrors

Alexander Dennis will show its new high-definition digital cameras and interior displays which replace traditional mirrors at this year’s Euro Bus Expo. The manufacturer says that the view from the SmartVision cameras is digitally processed to compensate for lighting, shadows or glare while it is transmitted to the displays, which are mounted inside the cab to eliminate reflections from windows. The system offers the driver a normal mirror view at the top of the monitor and a wide angle view in the lower half. Screen brightness adjusts automatically to give visibility day and night.

The offside display is mounted on the A-pillar, with the nearside display located centrally to avoid obstruction by an open door. SmartVision aims to maintain image quality in all conditions and software removes distortion from rain drops or dirt on the lens, while an optional camera heater clears ice or fogging.

In addition to improved visibility for drivers, operators benefit from reduced risk of mirror damage or injury to passengers or pedestrians, according to Alexander Dennis, potentially saving up to £25,000 per bus. A reduction in aerodynamic resistance is also expected to deliver a small fuel economy benefit, especially at higher speeds.

SmartVision is supplied by France-based Vision Systems through UK distributor 21st Century Technology. It is mounted during vehicle assembly and fully supported by ADL’s aftermarket network. The system is fully VCA-certified for the Enviro200 single-deck and Enviro400 double-deck.

First Glasgow and trentbarton have become the first operators to use the system. One Enviro400 for Glasgow’s service 75 is equipped with SmartVision, and one Enviro200 for the i4 route in Nottingham.
