DOT Focused Webinar

Pavement Marking Retroreflectivity Measurement & Data Management: the route to MUTCD compliance

We were delighted to be involved in this DOT focused webinar in collaboration with Paul Carlson (Automated Roads) and Rob Oram (Skip Line). There was a fantastic response with 163 registrations from 43 State Departments. During the webinar Paul highlighted how the mandatory minimum retroreflectivity of pavement markings really is a minimum. Road Agencies should be aiming for higher minimum to help improve road safety. This was echoed by attendees where 54% have set higher thresholds within their jurisdiction. 

The webinar highlighted how data management is a lifecycle approach to pavement marking management that enables DOTs to work smarter and not harder. This is particularly important given the challenges being experienced with retirements and low levels of recruitment in the industry. This begins with data logging at the time of application of the pavement markings. This is critical in ensuring traceability on the quality of the markings at the point of application. Combining this with regular retroreflectivity surveys ensures that data gathered can be used to prioritize restriping and maximise the bang per buck of restriping budgets. In addition, this data when gathered over time would facilitate more predictive maintenance where DOTs could focus on known areas of higher wear on the network.

The importance of safety-critical in-lane markings was raised as an area that falls outside the MUTCD ruling, yet is a key contributor to road safety, particularly for vulnerable road users. Joe highlighted how the Retrotek-D front mounted retroreflectometer is the only 3rd generation measurement system that simultaneously records all lane markings across the full lane width, including those in-lane markings. Survey processing and reporting has been greatly simplified in the QuickView visualisation software enabling rapid identification of pass/fail coupled with GPS tagged video footage of each marking. This provides agencies with a valuable inventory of pavement markings assets across their road networks.

It was pointed out that DOTs can combine the front mounted unit with other road condition assessment equipment mounted on the same survey vehicle to maximise data collection at the same time.

Our Customer's feedback

“Transport Infrastructure Ireland were very happy with the survey.”

“Transport Infrastructure Ireland (TII) were very happy with the survey results and impressed with the RetroTek-Pro software with interactive data base and video analysis. The timescale was tight (12 weeks) and delivery was enabled by the efficiency of the RetroTek system.”

“Impressed with the RL accuracy of the RetroTek.”

“We were very satisfied with the survey results and impressed with the RL accuracy of the RetroTek and the ability to detect the reflective pavement markings (RPMs)/road studs to within 3% accuracy over 1km. This information was very helpful in assisting our maintenance department to prioritise maintenance of road markings and reflective pavement markings (RPMs) / road studs where most needed and plan future maintenance schedules. The contract was delivered on time due to the efficiency of the RetroTek system to simultaneously measure the performance of multiple road assets in one pass.”

Andrew Elliot, Network Manager, M50 Concessions Ltd.

““ERA was very happy with the survey results and impressed with the RetroTek QuickView-Pro software.”

“ERA was very happy with the survey results and impressed with the RetroTek QuickView-Pro software with interactive data base, mapping and video analysis. It gives good overview of results and opportunity very easy to plan further road marking replacement plans. The timescale was tight and due to weather conditions, it was very hard to keep in timescale. But despite that the delivery was enabled by the efficiency of the contractor ERC Consulting Ltd and RetroTek system.”

Mr. Janno Sammul, Development Manager, Traffic Management Department, Estonian Road Administration (ERA)
