Development of highway alignment demands the planner to conduct map study, preliminary, reconnaissance and direct surveys. This takes much time and energy in preparing final drawings. Remote sensing acts as a very powerful tool to finalise the final alignment within less time and energy. The data...

As the OFROU needed a perfect alignment with the map they use in their GIS, Julien placed around 15 control points for each sub-project. But they were not the usual ground control points which are measured on the ground: instead they were extracted from theSwisstopo (Federal Office of Topog...
As for the rerouting of Monarch Pass, three plans were being examined in the 1930s. The plan that the city council of Salida and the Highway 50 Association supported was for Highway 50 to go over Marshall Pass (elevation 10,846 feet and then also the route of the narrow-gauge rail lin...
Preliminary surveys, aerial photographs, and detailed topographic maps of the grade crossing should extend outward along the railroad alignment for 1000 feet or to the end of any curves in both directions for the crossing. The survey should include: the top of rail of any track(s); the ...
Combining laser scanner altimetry data that is readily available to low cost GEM~(-2) electromagnetic surveys, allows for the refinement of the local geological model. Small and large-scale heterogeneities have been detected in this study. Their existence has been confirmed by a line of closely ...

(LiDAR) point cloud data are proposed.The procedure is a multistep procedure where the road centerline of each segment is first defined,after that a best fit alignment of points along the road's centerline is generated.A digital surface model (DSM) of the LiDAR highway is created and the ...
Zhu Zhaohong estimated the fuel consumption of different alignment sections based on vehicle speed, road impedance, and gear through field surveys and measured data in Germany to study the relationship between road alignment and fuel consumption [14]. Li Longfei analyzed the influencing factors of ...
