Way to Increase Transportation Safety
 

Nowadays, we have lots of bus on the road. It’s so convenient but also dangerous sometimes. I found a news in Wellington about bus monitoring system. I think it would be a trend in the future. Take a look of it (:
Wellington bus drivers will have the quality of their driving monitored by new technology, which will keep an eye on poor behaviour such as speeding, harsh braking and rough cornering. The new system would alert drivers when they were approaching the safety or efficiency thresholds NZ Bus had set for particular behaviors.
For each different behaviour a visual signal would start out green, changing to amber when the threshold was being approached and then to red when it was crossed, NZ Bus chief executive Zane Fulljames said.
The system was part of a broader training programme for drivers that would increase their skills and deliver smoother journeys for commuters, while reducing fuel emissions and the physical wear and tear on buses, he said. If you want to know this kind of system. Here goes the brief introduction of the system
There’s also some positive talk about the system. If you want to know more about the news. Please find the site below.

Arriva North-East DAF SB3000 buses (Plaxton Supreme coach-bodied) were fitted with 'idiot lights' (a string of LEDs that illuminated sequentially from green through yellow to red - several of each colour) that were supposed to indicate when drivers were operating economically (or uneconomically).

Some drivers kept the LEDs out of the reds as much as possible whilst others considered the system as a waste of time.

All these DAFs had their revcounters disabled, so it might have been that the LEDs were triggered from the revcounter feed, or from the throttle pedal position.

These DAFs (they were R-registered) have now been replaced by Scania Omnicity 07-registration buses as the DAFs were increasingly unreliable and resulted in a public outcry from passengers who were experiencing frequent delays and cancellations.

I have experienced one of these systems and noticed that many drivers find them de-motivational. The system that I have experience of (Greenroad) is a very blunt instrument, when moving off on an uphill section of road, it is very easy to register an "acceleration event" despite the vehicle being driven gently. When braking the device measures the initial deceleration and records an "event" irrespective of the driver's ability to come off the brakes and provide a comfortable, jerk free stop. If the brakes are applied when reversing the unit will register acceleration. The organisation marketing these devices offer the prospect of potentially huge fuel savings. I wonder if the claimed economies are ever realised? Would changing the gearchange parameters on the transmission produce a greater fuel saving?
