Mobile Mapping System Accuracy

<p>The proyect SIMGEOSEV (Driving Simulators and Geospatial Technologies for Traffic Safety Studies) studies the relationships between driver behaviour and road design variables using a driving simulator.</p>
<p></p>
<p>Data available are:</p>
<p>1- GPS Differential Correction Strategy</p>
<p>2- Speed</p>
<p>3- Lane</p>
<p>5- Discrepancies</p>
<p>6- Planimetric Error.</p>
<p></p>
<p>The data were acquired using a Mobile Mapping System (MMS), which enabled the capture of highly precise geometric and positional information of the road network. Data collection was conducted in both directions along the M-611 road at speeds of 40 and 60 km/h, ensuring comprehensive coverage of the study section. To guarantee accurate georeferencing, three methods were applied: Z60, based on a local GNSS differential correction; VRS, employing an RTK system with a virtual reference station provided by the Spanish National Geographic Institute (IGN); and SINGLE, utilizing RTK-mode data from the nearest permanent GNSS station managed by the IGN.</p>
