ARROWES TECHNOLOGY TRIAL REPORT:

Electronic Speed Awareness Sign (eSAS)

 

PROJECT:
CPB North East Link. 8-week
run of night shifts started
on Greensborough Road in
Yallambie, Melbourne Vic, to
install a new underground gas
utility pipeline.
LOCATION:
Greensborough Road,
Yallambie, Melbourne, Victoria.
REPORT BY:
Jeffrey Roberts,
CPB Traffic Manager

 

Background

Many vehicles were not adhering to the 40km/h temporary speed limit. Our night supervisor puts in the request for the safety risk to be addressed urgently before a serious injury occurred.
Having seen – and been very impressed by – a demo of the ARROWES eSAS at the Woolgoolga to Ballina (W2B) Pacific Highway upgrade last year, I knew the eSAS could be the solution to our problem.

I had assisted in getting the ARROWES eSTOP traffic signals approved by Roads and Maritime Services in NSW in 2019, so was already very familiar with ARROWES products. Like the eSTOP, the eSAS is highly portable and could be set up on its tripod and switched on within minutes. This also meant we didn’t need to tow another large trailer display unit to site.

Assisted by Havva Ahmet, Operations Manager at Construct Traffic, within 2 weeks we had eSAS units flown down from Queensland. The day the units arrived, they were set up, switched on and had an immediate effect with a great response from the traveling public through the worksite. Our night supervisor said the problem had reduced dramatically. This is the first time the eSAS has been trialed in Victoria on the tripod at a temporary traffic management site. The trial shows that drivers do adhere to the happy/sad face and multi messages.

 

 

eSAS results over 5 nights:

83% compliance under 40km/h
93% compliance under 45km/h
