Visualizing Pavement Distress – The Complete Story of Pavement Inspection

January 28, 2016

Pavement management incorporates data collected utilizing various methods to gain a complete view of how the pavement is performing through its life-cycle. One of the most common practices in pavement inspection is imaging utilizing high-resolution cameras mounted on vehicles outfitted with precision GPS and inertial navigation. This imaging, when combined with laser profiling, constitutes a typical pavement inspection setup utilized by many DOTs as well as Local government agencies.

Pavement Inspections tend to follow a process that in many cases is proprietary and “black box” in nature. This makes it hard for the purchasing agency to see how their roads were inspected and how the resulting pavement condition scores were generated. Our team of Engineers and GIS professionals have worked hard to develop a process to remove the “black box” related pavement inspection and to make it easy and simple to trace inspection results back to their originating distresses from the field.

First, our entire process is geospatial in nature from the get-go. Our van’s location is tracked in six-dimensions in real-time and this information is used to calculate the exact location of pavement cracks in the resulting images. Next, the pavement images are geospatially referenced in 3-d and 1mm-pixel resolution, making it easy to extract low-severity cracks in a true 3-d environment. This process then allows us to create GIS vectors (points, lines and polygons) of each distress for each pavement image and deliver them to our clients as part of the pavement inspection deliverables.

This is a crucial piece to the pavement inspection “story” because it shows the purchasing agency exactly what distresses were identified and measured when creating the pavement condition scores for a section of road. Being able to see these distresses on a map helps to complete the story by providing the ability for a rigorous QA/QC process utilizing some simple GIS tools.

Each Section of road can be colored by the condition score and its range of values. This tells one component of its story. The underlying distress information tells the rest of the story related to “How” a section of road was scored and assigned its inspection score. By having this information at their fingertips, pavement inspection personnel have a GIS-centric and user-friendly tool that allows them to QA/QC pavement inspection data efficiently.

DTS Helps State DOTs Meet FHWA ARNOLD Requirements

January 20, 2016

In 2012, FHWA announced that the Highway Performance Monitoring System (HPMS) data collection would be expanded in 2014 to include all public roads required under 23 CFR 460. This requirement was later entitled the “All Roads Network of Linear Referenced Data” or ARNOLD. A very helpful overview of ARNOLD from FHWA can be found here: https://goo.gl/H7o4F5.

Many state DOTs have been challenged by the expanded requirements as they focus on their State-owned system while local entities manage non-State public roadways. FHWA decided to help states build a sustainable all-roads network that meets the ARNOLD requirements through the ARNOLD Pooled Fund Study. FHWA is working with state DOTs through the development of individual work plans designed to meet their specific needs and DTS was selected to assist states through a variety of approaches. Activities may include the planning, development and maintenance of the network geometries and linear referencing systems (LRSs) as well as the development and maintenance of network attributes supporting HPMS, MIRE (the Model Inventory of Roadway Elements) and/or FMIS (the Fiscal Management Information System).

DTS is proud to be working directly with all nine participating states including California, Colorado, Florida, Georgia, Kansas, Minnesota, New Mexico, Pennsylvania and Utah.

The table below provides a brief listing of key project tasks and current status for each state.

Do You Have A Map-21 Compliant Asset Management Plan?

January 11, 2016

deadline

Has your organization completed the federally mandated, MAP-21 required Risk-based, Transportation Asset Management Plan (TAMP)? There are still many state DOTs which have not completed these plans. For some the daunting task of developing such a plan is hampered by the fact that the initial questions which need to be answered to begin have sometimes not even be contemplated.

  • What is the current state of your assets?
  • What is the Level of Service desired/necessary to maintain or achieve acceptable performance?
  • What/where are my critical assets?
  • What are the best strategies to employ for Operations and Maintenance and Capital Investments?
  • Where is the funding coming from to implement this plan?

There are examples available through FHWA of states’ plans:
https://www.fhwa.dot.gov/asset/plans.cfm

Key to these plans in addition to knowing what you have, where it is and in what condition it is, is understanding the likelihood and consequence of an asset’s failure. This is the risk component of the asset management plan – in other words, the ‘tree in the woods’ scenario. If a tree falls in the woods and no one is there, who cares? Likewise if an asset fails with little or no impact to system performance, the environment or safety, where is it on the prioritized list for funding or attention? More to the point, where are the critical assets that if they failed would catastrophically affect safety and/or performance?!?!

DTS stands alone in the transportation industry as the ONLY firm that understands and has experience with the full cycle of asset management, from data collection, feature extraction and condition assessment to planning, work management and operations and maintenance. Others collect data, while some offer software systems, but DTS alone has the necessary expertise and experience to support your agency through the entire process.

Happy New Year!

Data Assets are Assets

December 15, 2015

data loss blues

Did you hear the one about the asset collection vendor that lost your data? Not a joke, and a painful horror story from one of the other data collection companies out there. We are proud to say at DTS and VUEWorks that we have never lost a client’s data… ever! And we do not intend to…ever! Having a strong awareness of the type and value of data that a vendor is protecting has become even more critical as technology platforms continue to evolve.

As cloud computing becomes a more prevalent phenomena daily, major challenges emerge for protecting large asset management datasets, linking through firewalls and displaying information that is compiled across multiple IT architectures and frameworks.

Moreover, In our present climate where public infrastructure is a target – controlling access to data once thought mundane takes one a new level of importance in the era of domestic terrorism. Knowing and protecting the location, criticality and condition of infrastructure is paramount to protecting public safety as well as providing timely and up to date information to first responders.

These data sets are costly to develop, expensive to maintain and represent a significant investment of tax payer funded resources. Protecting this data should paramount when considering asset management as a program, not just a project. There are several considerations that need to be well thought out in scenarios including, but not limited to:

  • The need to create a report: Who has access? And access to what within the AMS?
  • Sensitive information: How is it protected? How are permissions handled?
  • Systems: Who has access to test, staging and production environments? Are they allowed to add/upgrade applications?
  • Backups: What is the process for securing backups of both spatial and non-spatial data?
  • Hardware: Outdated? Using cloud?
  • Security: Improper configuration settings? Inadequate security controls?

It is important to take into consideration data loss prevention. These are processes put in place to address the areas listed above, to ensure that there is a methodology consisting of people, process and technology that protects your data. Consider the following categories and see if your organization has a data loss prevention methodology in place:

  • Data Discovery
  • Data Governance
  • Risk Assessment
  • Regulatory and Privacy Compliance
  • Data Classification
  • Policies, Standards and Procedures
  • Remediation Processes
  • Training and Awareness
