2 Make sure glass is flush with mirror shell Driver should tell you where to align mirror head Small adjustment of glass Flat should see top of 3ft cone 15 ft back Overlap convex view with flat glass

3 Vehicle is 10ft back from mirror If you can t see the vehicle in your flat glass don t even think about changing lanes!

4 Side Blind Spot

5 Mirror 3x further than driver s side mirror Difficult view unload/loading FOV narrow Windshield grime, rain, snow & wipers impair visibility even more

6 MIRROR HOME POSITION REAR POSITION FORWARD POSITION Adjustable Home Position - eliminates damage from bus wash - no readjustments - adjustable home position reduces fixed object incidents

7 (Front) Sideswipe 46% of bus accidents occur on the left or right side of the bus! Angle Bus Point of Impact Total Fatal Injury Front 25% 64% 37% Sides 46% 1 14% 36% Rear 19% 16% 25% (Back) 33% of total transit crashes are sideswipes 2 1 FTA 2002 NTD 2 Dunn/CUTR

9 Injuries, fatalities and overall operating cost can decrease Impacts availability of buses for revenue Adds to cost of providing transit services Positively impact the public s perception of transit Transit operators less stressful driving

10 Reducing Transit Bus Side-Collisions* One of the major reasons that side crashes occur drivers cannot see other vehicles or objects in the blind zones of the mirrors of the bus Current mirrors all have some blind zones Less effective during adverse weather (rain or fog) Drivers cannot see vehicles approaching from the side, especially during lane change maneuvers. A Study was performed utilizing side cameras and it was determined that blind zones can be completely eliminated *FDOT: BDK85 Two March 2010

11 In average daily commutes, drivers change lanes once every 2.76 miles. This increases significantly in suburban rush hour commutes. 1 out of 25 accidents on America s highways today is due to unsafe lane changes and merges; That s approximately 630,000 collisions every year. Trained to look over the shoulder to view blind spot Vehicle Speed Total Head Turn Time 1.6 sec 1.8 sec 2.0 sec 55 mph 129 ft 145 ft 161 ft 65 mph 152 ft 171 ft 190 ft 70 mph 164 ft 184 ft 205 ft Chart shows how far your vehicle travels unattended while your head is turned to check your blind spot.

13 Visible to mirror Blind to mirror

14 Sideview camera on side of bus Monitors on driver s dashboard

15 Vehicle not visible Vehicle visible in camera

16 Device % Reduction Left Side % Reduction Right Side Flat Mirror Convex Mirror Regular Angle Lens Wide Angle Lens

17 View for two different drivers View remains same for all drivers

18 Infrared LED s provide Nightvision

19 During rain difficult to see mirror

20 Benefits of Cameras on Buses: Protect drivers Enforce rider regulations Prevent theft Deter violence Enhance passenger safety Crime investigation

21 Majority of drivers agreed that: The system reduces or eliminates the side blind zone compared to the mirrors The system can help drivers reduce side crashes by providing a better view In general, the system can improve bus safety With the system they can observe late arriving passengers Drivers would like to have this system on the bus they drive everyday Felt comfortable performing a lane change maneuver with the system The system can help reduce crashes during lane change maneuvers

22 Based on findings from this study, phase II was proposed to: Investigate the best setup and specification for the enhanced sideview system Integrate camera system with mirror and produce a prototype Deploy with transit agency to evaluate effectiveness of integrated mirror-camera system and collect driver feedback Create specifications for future integrated mirror-camera systems for transit buses

27 Vision CTQ s* Must Haves! Adjustable home positioning/detent Provides consistent location (FDOT Safety Rule14-90) Eliminates bus wash damage Mirrors should be OE compliant Die cast aluminum construction Superior stability and corrosion resistance Anodized/Powder Coating Increases corrosion & wear resistance Superior paint adhesion for paint primers More durable than conventional paint (automotive quality) Optional: Integrated cameras (CMOS with 60 or 100 degree FOV) Two monitors located on dashboard (5.6 inch diag.) CMOS back-up camera (100 degrees horizontal) *Critical To Quality Characteristics
