 Ultrasonic Obstacle Detection - Improving Vehicle Safety in the Workplace

Ultrasonic obstacle detection devices

Sensing danger in the workplace
Blind spot legislation is extremely topical. Over the last few years vehicle safety devices such as extra mirrors or camera monitor systems with wider viewing angles have become mandatory. However, despite an increase in all-round visibility, collisions with other vehicles, fixed objects, cyclists, workers and even pedestrians, remain high.

The issue of cyclist fatalities has been of particular concern, with more than half of all cyclist deaths in London attributed to collisions with HGVs. Fiona Hall MEP, who tabled a European written declaration on the matter, says: “Sensors and cameras should be compulsory on all lorries so that drivers are always aware when someone is close to their vehicle. This is everyday technology used .
o help car drivers with parking – on lorries it will save lives.”

Ghost Bikes are becoming an increasingly common sight worldwide, a sombre memorial for a cyclist killed on the road. A bicycle is painted white and placed near the crash site, accompanied by a small plaque.

“By fitting Brigade’s Ultrasonic sensors, we are achieving a very high standard of health and safety on public highways both for Keltbray and other road users.”
Adrian Scott, Haulage Operations Director, Keltbra

Ultrasonic warning devices for vehicle safety supplied by TTS

How Brigade Ultrasonic Devices can help
Brigade’s ultrasonic detection and warning systems alert the driver of potential danger. An audible warning informs the driver of the distance between vehicle and obstacle, minimising both vehicle damage and collisions with pedestrians, cyclists or objects. Activation triggers (eg: reverse gear, left indicator) ensure the system is only operational when it is needed and an optional speaking alarm can be added to alert cyclists and pedestrians of the vehicle’s path.

Brigade’s range of ultrasonic sensor systems include Backscan, Frontscan, Sidescan, Cornerscan™ and Stepscan™ and provide the following benefits.

> Gives peace of mind to the driver, greater protection to pedestrians, cyclists and workers

> Minimises damage to vehicle, property and other objects

> Can be used in conjunction with Brigade’s camera monitor
system for comprehensive all round blind spot coverage

The cost of turning a blind eye
Even a relatively small accident can be immensely costly to a fleet operator. Apart from repairs to the damaged vehicle, there is downtime and replacement vehicle hire costs to consider and this doesn’t take into account any insurace or legal expenses.

Typical damage costs based on a Mercedes Actros:

Item

Cost of Replacement

Step (bottom part moulded

295 - 585

Bumper - two comers and centre

248

Under run bars (box section welded)

385

Whole Front light cluster

246

Rear light

134

Yet the consequences can be even more severe.

A company was fined 105,000 in September 2009 after an employee was killed by a reversing lorry at the skip waste site where he worked. The man was in the lorry’s mirror blind spot when he was struck by the rear of the lorry and run over.

 Ultrasonic Obstacle Detection

Two, three or four sensor ultrasonic sensor systems inform driver of distance between vehicle and any obstacles, whether moving or stationary. Perfect for road going commercial vehicles regularly operating in confined spaces or manoeuvring at low speed.

Features of all systems:

• Obstacles detected in under 200 milliseconds
• Environment Learning Mode prevents false alarms from permanent bodywork that intrude in the first 100cm of the detection zone
• Self diagnostic function
• Fixings included for all bodywork types
• Three stage audible distance warning to driver
with adjustable volume

• 1 trigger output
• 2 year warranty

Sidescan® Case Study

Safety on the Side
Cemex, a leading supplier of cement, ready mixed concrete and aggregates adopted a range of safety measures to resolve the issue of cyclist and HGV collisions. 

Cemex fitted a range of Brigade’s safety systems to its tippers and mixers to improve the driver’s field of vision and make their vehicles more visible to pedestrians and cyclists. The combination systems include Brigade’s movement sensors (Sidescan) and talking alarms (Backchat) to alert both parties to potential danger.

During an FTA Seminar, Paul Clarke, Logistics Fleet Engineering Manager at Cemex said “Between 2000 and 2004 vehicles operating on our behalf were involved in 6 road
traffic accidents involving cyclists
on the nearside, two of which sadly resulted in fatalities, however...

Cemex

“...since fitting Brigade Sidescan as part of a wider programme of road safety initiatives, we have not experienced any blameworthy road traffic incidents involving cyclists on the nearside.”
Paul Clarke Logistics Fleet Engineering Manager, Cemex

Road Peace

Transport For London trialled blind spot technologies including Sidescan. Respondents found it particularly helpful in slow manoeuvres, tight spaces and felt it performed well in the dark.

Crossrail has set minimum standards for safety equipment for their contractor vehicles including side sensors.

Lafarge have set a worldwide target standard to install Brigade safety equipment to their vehicles including Ultrasonic Detection Systems. To view the Lafarge video case study, visit: brigade-electronics.com

RoadPeace has prepared a briefing for coroners and collision investigators on how blind spots can be eliminated using life saving vehicle safety equipment, such as sensors.

Backscan® Case Study

Every little helps when it comes to Safety
The convenience and popularity of internet shopping has led to a sharp growth in home delivery. However, the increase in number of large cars in small residential streets coupled with the rear blind spot has made reversing and parking manoeuvres very difficult.

Damage to property and parked cars is costly and many operators can ill afford vehicle downtime for repairs. More startling is the real threat of collisions with pedestrians. According to the Health and Safety Executive (HSE) 25% of all workplace fatalities are caused by reversing vehicles.

Tesco.com is the largest online grocery store in the world. Drivers were experiencing problems reversing due to the huge blind spot at the rear of the vehicle and were also reporting damage from overhanging trees, especially in rural areas...

Brigade solved the problem by fitting
upper Backscan sensors to protect the Mercedes Sprinters from overhanging branches. In addition, lower Backscan sensors were fitted to the bottom of the delivery vans to detect people and objects in the blind spot when reversing.

Tesco

“We are very pleased with the performance of Brigade’s Backscan which enables home delivery drivers to reverse into tight spaces. This ensures the safety of pedestrians and property, thus reducing damage to the vehicle.”
Duncan Vavangas. Fleet Engineer, Tesco.
