Network Level Survey for Wagga Wagga City Council

RPS scanned 2200km of the Wagga Wagga City Council's road network

In 2012 RPS was commissioned to scan the 2200km of the Wagga Wagga City Council road network in order to produce crack mapping and road condition stats for loading into their PMS. This allowed them to prioritize the roads included in their crack sealing program as well as have a detailed overview of the condition of their network.

Wagga Network - 2200 lane km

Site 1: Mima St - North Glenfield

Crack detection using photometric system:

Normal black and white image of the road surface (only one crack is barely visible)

Same image using the photometric forward angle (two longitudinal cracks are clearly visible)

Same image using the photometric angle colourisation to highlight the cracking features

Cracks tagged in Portal4D. Crack width is automatically estimated showing a colour code depending on its width.

Sample of kml file geospatially locating the features found during the surface analysis. Features are colour coded to represent severity and type.

Inspection of the road was performed after data was reported. Image showing the crack found in that location. Crack has been found using the kml file as reference.

Image taken by the PaveScout3 system on May-2012. The cracks are visible in this view.

Environmental images taken by PaveScout vs. still images taken by the Council.

Image taken by the PaveScout 3 system on May-2012 at the exact same location as the Council's image.

Image taken by Council's workers during inspection on foot Oct-2012.

Site 2: Bourke St

Image taken by PaveScout 3 on March 2012, note that cracks are not clearly visible.

Image taken by Council worker's during inspection on foot - Oct 2012 (cracks not visible).

Image showing the photometric forward angle in that location (cracks clearly visible).

Image showing the photometric angle colourisation view in that location (cracks clearly visible and highlighted).

Cracking KML output file showing the location of the reported cracks geospatially.

Crack found and recorded during inspection on foot. Cracks were included in the crack sealing program based on the data provided by RPS.

Output: Data for the entire network was loaded into SMEC PMS and MapInfo. Stats for several surface defects and conditions are reported.
