VRIOGS 003.2-2006 16Figure 4 : Active Crossing Layout- Preferred DesignTACTILE GROUNDSURFACE INDICATOR* Minimum distance should be increased to allow for curve effects when the track radius is lessthan 600m.All dimensions are from face to face. That is opening dimensions are taken from the inside face ofeach bounding member. Structure dimensions are taken from the outside face of boundingmembers.Part or all of posts C and D facing the rails to be painted or marked to provide a clear luminancecontrast with the background. Yellow paint or chevron hazard marking is deemed to comply withthis requirement.NOTE: This Document is controlled only when viewed on the DOI Engineering Standards Web Site.

VRIOGS 003.2-2006 17(a) Clearance to Adjacent Road BoomsIn some cases the gate motor would be located close to a road boom barrier. Figure 5 showsthe normal minimum clearances to ensure acceptable levels of safety for maintenance staffworking on both pieces of equipment for the case when the boom and the gate motor wouldbe located in the same enclosed space.Figure 5 : Normal Minimum Clearances- Preferred Enclosure LayoutROAD BOOM322032004300 (typical)3950 (typical)GATE FENCECentreline of nearest track(b) Reduction in Clearance to Adjacent Road BoomsThe clearances shown in Figure 5 may be reduced if it can be shown that equivalent levels ofmaintenance worker safety would still be maintained. Techniques that may be used to reducethese clearances include the following.Use of a shorter and heavier boom counterweight.Application of a machine guard around the outer end of the boom counterweight.Special safety procedures applied to staff undertaking maintenance.Increasing the difference between the offset from the rail track of the gate motorand the offset to the road boom. Oblique crossings will increase (or decrease) theeffective lateral offset of the outer end of the boom counterweight depending onwhether the angle is greater or less than 90 degrees.5.3 Alternative Enclosure DesignFigure 6 shows an alternative Active Crossing layout with the gate motor in the escape path.This layout is deemed to be acceptable only where site specific circumstances prevent theadoption the preferred layout. The alternative layout incorporates a motorised gate with thehinge on the side of the escape path.If a boom mast is located nearby a minimum clearance of 2m is required from the enclosurefence to the boom mast. This is required to ensure adequate clearance to the movement of theroad boom counterweight. This clearance can only be reduced in special circumstances bymeasures such as those outlined in Clause 5.2 (b).NOTE: This Document is controlled only when viewed on the DOI Engineering Standards Web Site.
