Blind Spot Detection – Protecting Vulnerable Road Users
11.11.2018 Collision Avoidance
Probably the most important step toward smarter, greener cities is learning how to integrate a wide variety of transportation types. Cutting down on private cars is key to reducing congestion and pollution but they need to be replaced by something – walking and cycling are the greenest substitutes, supplemented by buses for mass transportation. And of course lorries will always be needed for deliveries and other services that just can’t be replaced. This is where smart city planners hit a stumbling block – roads are being dominated by both larger vehicles and the most vulnerable road users – pedestrians and cyclists.
According to Transport for London, although Heavy Goods Vehicles (HGV) account for only 4% of the miles traveled within London, they are responsible for 50% of cyclist fatalities and 23% of pedestrian fatalities. The group also notes that the large blind spots associated with these vehicles are a major contributory factor in collisions. In fact, fitting HGVs with blind spot detection systems is one of the core components of the groups Safe System program. The need for blind spot detection is bolstered by statistics from The Royal Society for the Prevention of Accidents (ROSPA) which reports in 2017 that 55% of cyclists severely injured in London occur when an HGV turns left across the path of the cyclist, often because they are in the HGV’s blind spot.
In addition to HGVs, urban buses also pose a hazard to cyclists and pedestrians. According to a 2005 article in the Injury Prevention journal, the rate of fatal collisions in urban areas by buses far exceeds that of any other type of vehicle. Here again blind spot detection seems to be a serious issue. According to Greater Greater Washington magazine over 500 people died between 2000-15 due to buses’ large blind spots.
In response to this pressing need, Mobileye Shield+™, a collision avoidance system for large commercial and municipal vehicles, was specifically designed to help HGVs and buses safely navigate the urban environment. Shield+ includes the features you expect to find in a collision avoidance system such as a headway monitoring warning to keep drivers a safe distance from other vehicles, pedestrian and collision warning, alerting drivers to the presence of pedestrians or cyclists ahead of them but also includes features of special importance to large vehicles navigating city streets.
The blind spot detection system constantly monitors a lorry or bus’s blind spots, warning drivers when pedestrians or cyclists enter these dangerous areas. Equally important, the system is intelligent enough to ignore inanimate objects and to distinguish between situations where the driver needs to be warned and those where immediate emergency action is required.
There is also a big bonus for smart city planners. Shield+ includes hot spot mapping, giving you concrete information on danger zones and potential hazards along your city’s transit routes.
In the field, Shield+™ has already started producing results. During a pilot study conducted by the Washington State Transit Insurance Pool none of the buses equipped with Shield+ was involved in a collision - as compared to 284 events experienced by non-equipped buses. Following the success of this study, one of the participants, Pierce Transit decided to retrofit it’s entire fleet of 176 vehicles with Shield+ and shortly afterward the Barcelona City Council decided to install the system on some of its municipal vehicles.
Between blind spot protection and smarter city planning we can start making serious strides toward cleaner, less congested cities while simultaneously progressing toward our goal of zero pedestrian and cyclist fatalities.
