LiDAR for Transportation Industry
LiDAR has transformed the whole process of working in the transportation industry, whether it’s planning, designing, construction or maintenance, transportation industries are now unimaginable without LiDAR technology.
With aerial lidar, a wide range of area is mapped at a time, this technology makes it very easy to understand the transportation system in a wide area, where drone lidar and mobile lidar, is capable to measure the exact width, elevation, length of a road, gutter around the roads, bends on the road, vegetation around the transport path etc.
LiDAR technology helps transport industry in multiple of areas which can be summarized into these 3 sections
Planning
LiDAR comes into effect in surveys where a manual survey is either not possible or quite time taking. For a road or rail line to be built on a mountain, it is quite important for the engineers to have a complete digital terrain model(DTM) of the site along with the details of the vegetation, rocks etc around the proposed site, also digital elevation model (DEM) for the site is needed to find the elevation measurement which helps in deciding the right path for the proposed route, which will incur in less time and investment.
Maintenance
Over time many things change in the transportation industry either slowly or rapidly. The transport path deteriorates, vegetation grows or depletes, new construction happens. With the ever-changing environment around transportation paths, digital terrain models of the transportation path help in understanding the safety challenges, maintenance required etc.
Accident Study
In case of an accident on the transportation path, LiDAR data helps in a number of ways,
- How to divert the traffic after an accident
- The shortest way to the hospital from the point of accident
- Accident case study
- How to avoid such accidents in the future etc.
LiDAR is like an artificial eye on the roads which can help in making, maintaining, the safety of our transport system.
