Understanding Assets

Each dot on the map represents a road sign. Click on a dot to see the qualities and status of each sign. Red dots represent signs that need attention. Repair technicians can reset the status to green once any outstanding issues are addressed.  

After observation, our inspectors use this map to document the current repair status of each overhead sign present on the project route. Each sign's qualities and features are recorded alongside any possible damages or deficiencies, resulting in an easy-to-understand overview of the state of the region's signage. When a sign requires attention, its node is marked as red; signs of acceptable quality are green. This visual combination allows NCDOT repair technicians to plot their repair routes efficiently, cutting down on time needed to complete necessary asset maintenance.  

Each segment of the sidewalk surveyed is marked by a color-coded line, with green indicating a sidewalk section that does not require attention and red representing sections that need immediate attention. Click on a segment to learn more about the pavement quality, with supplementary pictures attached.  

The Hillsborough Sidewalk Rating map is a community-oriented effort to address local concerns about the usability of their paved pedestrian spaces. Each instance of a sidewalk on this map is recorded using an inspector who walked the premises, taking pictures of any faults, damages, or defects in the pavement. As our goal is to improve accessibility and ease of use, great consideration was given to complications that would hinder a pedestrian’s ability to safely and easily access the sidewalk. These steps, alongside ensuring that curb ramps are usable and in good repair, are critically important to ensuring that Hillsborough’s sidewalks are ADA-compliant. 

The condition of the pavement itself was not the only aspect recorded in this initiative. Other factors, such as overgrown foliage, contributed to the issues faced by pedestrians in the community. By manually reviewing the walkways, inspectors encounter complications the same way an average pedestrian might.  

Our inspection process is assisted by DeepWalk, a cutting-edge technology that can be held in the palm of your hand. Our inspectors start by recording sections of pavement using their iPhone cameras. DeepWalk then uses LiDAR to analyze these sections and create points on a data map for later analysis. The detail captured by DeepWalk creates intricate images that can show exactly where there are issues within the sidewalk sections. This data can be added to our GIS maps, providing a broader understanding of any issues present in a section of pavement. 

The dots on this map represent bridges that have been or will need to be inspected. Color-coordination denotes the method of assessment. Click on a bridge to learn more about it.  

The methods for inspecting bridges can vary wildly depending on the location of the bridge and the features of its surroundings. This map’s purpose is to take inventory of existing bridges within the project scope and assess their condition and quality. The map also accounts for the method of assessment, such as by drone, barge, or snooper. Once the quality of the inventoried bridges are assessed, work on any repairs can begin. 

This map depicts both routes and staging areas. Routes are depicted with color-coordinated lines, while staging areas are marked by stars. Click on a segment or staging area to read more about their features. 

This map depicts both the staging areas and routes for snow removal in Durham, North Carolina. Utilizing “Real Routing” tech, snow removal teams can auto calculate the most efficient routes for the streets they need to service. These routes are then recorded on the map, which also provides directions to and from locations. This enables technicians to rapidly address heavy snowfall within Durham, increasing transportation safety.
