On the Urban Transit Route

Mirrors

The principles of mirror adjustment and usage are common core to all sectors. In this example we are demonstrating this cross sector application by using a School Bus graphic and photos.

At the start of each shift, an operator needs to make sure all mirrors are adjusted to fit his or her sitting position. Mirrors are adjusted manually, electronically and with levers and dials.

A=Cross-over mirrors
B=Side convex mirrors
C=Side flat mirrors

Left / Right Front Cross-over Mirror
Provides a complete view of the blind area directly in front and to the right or left of the bus. These are used on school buses.

Left Side Convex Mirror
Convex portion is at the bottom of the mirror housing.
Provides a clear view for a distance of 60 meters (200 feet) directly behind the bus on the left side. The left and right side need to converge in the line of sight. 

Right Side Convex Mirror
Provides a clear view for a distance of 60 meters (200 feet) directly behind the bus on the right side. The left and right side need to converge in the line of sight.

Left Side Flat Mirror
Flat portion is on top of the convex mirror. Provides views of the left side of the bus body. When viewing the bottom right hand corner of the mirror, the rear tire on the ground and up to the lower window line on the side is visible.

Right Side Flat Mirror
Provides views of the right side of the bus body. The mirror arm must be set at an angle nearly 15 degrees away from the bus to view the relationship to right side objects such as, curbs and vehicles, and to view customers exiting the centre bus doors.

Interior Mirror
Provides the widest view of the interior, rear window, and right side clearances through the side windows. Provides views of passengers and a partial view of what is behind the bus. Operators are aware that the body of the bus creates many blind spots in this mirror.

Exit Door Mirrors
Used in combination with the right side flat mirror to give a view of the exit door stairwell and the area immediately outside the bus, at the exit door. This mirror is used on transit buses.
