The Cost-Benefits of Data Collaboration

One of the biggest challenges facing county and state transportation departments is how to make their road and highway data accessible to different divisions within their organization. When organizations don’t have the right tools to share data, it can result in the same or similar data being collected by different divisions. This can cost organizations time and ultimately money, forcing them to perform additional collection efforts when the data may already be available within an agency, but not easily accessible by other staff divisions.

One way to solve this challenge is through data management. While a data management system might seem costly and complex, an experienced consulting team can provide a practical and cost-effective solution that fits the needs and budget of an organization. Mandli Consulting Services offers guidance and can suggest solutions on how to get the most out of your data so everyone in the organization is able to access it, view it, and use it for planning purposes.

Mandli’s Consulting Services team recently worked with both Utah and New Mexico DOTs to develop customized solutions for their data management needs.

Utah Department of Transportation (UDOT)

Utah’s Department of Transportation (DOT) wanted to set up a system that would allow its different divisions to be able to collaborate in collecting and sharing road and highway data. That is, once data was collected, it could be available to everyone.

Mandli’s Consulting Team worked with Utah officials in multiple departments to assist with implementing this department-wide collaboration, using previously collected Mandli data. Having performed three statewide collection cycles since 2012, Mandli’s data, combined with this project with UDOT, contributed to the development of the UPlan ArcGIS Online Portal. The UPLAN portal was designed as an accessible interactive mapping platform to help staff across the DOT visualize their data and track their assets for planning purposes.

To make UPLAN a reality, Mandli worked with UDOT’s GIS Department to use the collected data to identify changes and required updates in their LRS Centerline layer. Utah personnel, HPMS Reporting Division, are able to use year-over-year GPS collection traces to identify route segments where additional lanes have been constructed between collection cycles.

UPlan is now being referenced by FHWA as a suggestion for states for statewide data collection and roadway inventory.

New Mexico Department of Transportation (NMDOT)

NMDOT recently completed the second stage of a multi-phase project with the overall goal of implementing a linear referencing system to satisfy FHWA’s ARNOLD requirements.

Phase 1, completed in 2016, focused on the collection and development of an initial road network from multiple data providers. Mandli collected about 15,000 miles of data which included imaging, positional, pavement data using LiDAR, and the Laser Crack Measurement System (LCMS) to calculate faulting, distress, IRI, and rutting.

Phase 2, completed in August of 2018, involved establishing Esri’s Roads and Highways Linear Referencing System as the new recording system for the DOT. Mandli was tasked with establishing this new system. Our team performed all cleanup, migration, calibration of the initial network, and system implementation tasks. The new RIS (Roadway Inventory System) now serves as the foundation and integration point for other systems including Road Inventory, HPMS reporting, and so on.

With the completion of Phase 1 and 2 complete, NMDOT has continued to use Mandli’s Consulting IT Services. We have been asked to work with NMDOT staff to ensure the RIS is operating to its fullest potential and employees are able to get the most of out of the system and their data.

Mobile Mapping Solutions

Adding portability to mobile mapping technology creates a powerful tool, providing solutions that extend beyond roadway asset collection.

For the San Diego Metropolitan Transit System (MTS), a portable mobile mapping solution was precisely what they needed to get information about their infrastructure.

Between the light rail system and bus routes, San Diego MTS manages 106 miles of track and almost 100 bus routes that serve over 275,000 people every month. In order to understand their routes better, San Diego MTS wanted to get the routes mapped and compile a list of all of the assets along the course. The challenge was figuring out a way to get a mobile mapping unit on the rail line without interrupting service or affecting travel time for any passengers.

San Diego MTS contracted Mandli Communications to collect information for all of the rail and bus routes in their county. Mandli developed a customized solution for San Diego MTS using our portable 3D imaging and LiDAR collection system, Maverick.

With our portable mobile mapping technology, we still had to address how to get the Maverick onto the rail line without disrupting service. Mandli developed a prototype suction cup mount for San Diego MTS, which allowed the Maverick to be attached to the windshield of any commuter train. This removed a key hurdle and provided a way to collect and map information with no traffic interruption or service delays.

The prototype mount meant that Mandli was able to collect all of the data along the 106 miles of track that MTS wanted in less than one day.

Data from the Maverick provided MTS with an accurate GIS inventory of all trackside assets, allowing them to monitor track condition. With the maps, images, and LiDAR point cloud accessible via a desktop software application, San Diego MTS employees could drive the tracks and routes and use the system to train new employees in the office.




Mandli Communications is NCAT Certified for IRI!


Mandli Communications’ pavement technology is NCAT certified for IRI using Pavemetrics’ high-speed 3D laser pavement profiler (the LCMS). We are the first company to collect, process, and deliver passing results all in the same day for both the LCMS-1 and LCMS-2 technology!

Through joint efforts with Pavemetrics, we are very proud to announce that Mandli Communications received Profiler Certification for Dense Graded Asphalt (DGA)/Open-Graded Friction Course (OGFC) through NCAT. Over the weekend a team from Mandli drove our collection vehicles with the LCMS-1 and LCMS-2 down to the National Center for Asphalt Technology at Auburn University and officially passed NCAT’s longitudinal profiler certification program. This certification means we now meet the AASHTO R56 requirement per NCAT and are HPMS compliant.

Mandli is proud to have worked with Pavemetrics’ to achieve this industry milestone. Receiving this certification validates the LCMS-1 and LCMS-2 as accurate and repeatable inertial profilers that are an acceptable alternative to older profiler technology.

The LCMS Pavement Scanners are known for providing automated crack detection and distress classification across the entire width of the lane, in a single vehicle pass. IRI is collected with the addition of high-precision Inertial Measurement Units (IMUs) to each of the LCMS sensors in order to measure and isolate the effect of vehicle chassis motion during the measurement of longitudinal profile.

Post-processing algorithms are provided to extract a longitudinal profile from LCMS data and to calculate IRI measurements from collected profiles. The results are equivalent to an ASTM E-950 Class 1 profiler, with the addition of offering 4,000 points of roughness measurement across a 4meter width, compared to traditional profilers which offer only point lasers in the wheel path or simple line lasers limited to 0.1m scanning width. This more repeatable and accurate IRI data gives Mandli greater confidence in the information we collect and proves more effective for guiding pavement preservation and improvement work.

LCMS certification further cements Mandli’s position as a leader and key innovator within the industry. Mandli’s mobile data collection solution to collect all information in a single pass represents a huge value and cost-savings solution to our customers” said Raymond Mandli, President of Mandli Communications.

Profiler certification is considered the ultimate test of pavement profiling equipment and is often required before a State DOT will permit the use of a specific profiler. Auburn University’s NCAT site is one of only three sites in the United States that has both the necessary facilities and the expertise to certify pavement profiling equipment.
