Asset Management
Roadside asset management is an important subset of an overall Road Asset Management Program, and can be defined as the process by which all assets other than the pavement itself are inventoried, valued and managed by the road owner. Examples of assets include: signs, poles, guardrails, security barriers, stop lights, pavement markings, bridges, mileposts, etc. "How many?", "Where is it?", and "What condition is it in?" are some of the questions that need to be answered to meet Asset Management principles.
Trimble's Mobile Data Capture Systems generate detailed information to populate Geographic Information Systems (GIS) and Asset Management Systems (AMS). Stakeholders will not use these systems to the fullest extent possible unless they can trust that the information is both complete and accurate. Our solutions provide the data capture and office analysis tools to complete this work efficiently and confirm its completeness and accuracy.
The number of assets and the number of different types of assets that need to be managed are staggeringly large. The most important question you need to ask when considering investing in this technology is: "How efficiently and accurately will the imagery and laser scanner data be converted into information?" At Trimble, we understand this and are investing in automated asset detection and identification.
With Trimble Trident-3D Analyst software, all asset types can be manually detected, identified, and georeferenced from imagery using photogrammetry. Trimble Trident-3D Analyst also provides the underlying ODBC database connectivity tools and feature export utilities to log asset features and attributes to existing GIS or AMS applications. And that same data can be exported from the GIS or AMS back into Trimble Trident-3D Analyst for change detection between two data sets. For example, all missing road safety signs can be quickly identified.

Additionally, Trimble Trident-3D Analyst automates the detection and identification of some types of road assets such as signs, poles and pavement markings from combined imagery and laser scanner data. This provides very significant improvements in efficiency, accuracy, and most importantly turnaround time. The sooner you know there is a problem with an asset, the more quickly it can be resolved. In the case of road safety signs, this can be a matter of life or death.

The simultaneous capture of high-resolution imagery and laser scanner data has opened up new applications and created new workflows previously not possible. 3D, 4D (plus time), and 5D (plus cost) models can now be generated efficiently with minimal turnaround time, then served over the internet to all stakeholders. These stakeholders can then perform additional virtual measurements and capture additional attributes without a site revisit. And they can even process the models with their own domain-specific applications.
The accelerated adoption of this technology will increase the productivity and workflow efficiency at all levels of your organization.
