5.7.4.3 General Detector Installation – Non-Ideal

It is recommended that the standard installation and cranked pole installation is used.

However, if the user requires the general installation details are provided.

The Kerbside detector should be aligned downwards, to cover the area of the kerb

adjacent to the crossing. The normal detector angle (pre-set at factory) is 60 degrees.

The detector must be mounted so that there is no obstruction between the detector and

the detection zone. Failure to adhere to this recommendation can reduce detector

performance.

If the mounting pole has a near-side attached, the Kerbside detector should be mounted

such that it is at least 7cm away from the side of the nearside and at least 9cm in front.

See Figure 30 below.

This is normally achieved by using a standard Kerbside mounting bracket, but the

extension bracket may also assist in meeting the mounting requirements. There are

several mounting positions available on the standard Kerbside Mounting Bracket for the

Kerbside Extension Bracket, two bolts must be used to secure the two together in all

instances.

Failure to meet these mounting requirements may mean the detector will operate non-

optimally and therefore performance specifications are not valid.

Figure 30 : Kerbside Detector Mounting Details

The optimum position for the detector is 0.75m from the edge of the carriageway.

However, distances between 0.5m and 1m can be accommodated.

It should be aligned parallel to the kerb edge and face downwards to the aiming point as

shown in Figure 32 below.
