TRENTON, NJ (ASSET INVENTORY) - Rodriguez Consulting LLC (Rodriguez), under contract with Taylor Wiseman & Taylor (TWT), provided geospatial and transportation asset inventory services for Delaware Valley Regional Planning Commission (DVRPC) for the Mercer County Signage asset inventory project. The purpose of the project was to assess the locations of existing county-owned traffic signs and gather retroreflectivity properties of the signs and its height with offset.
Rodriguez was responsible for providing geospatial and asset inventory services:
- Field Data Collection– Rodriguez utilized Mercer County Sign Management Application software to build a GIS database of Mercer County`s traffic signs and collect digital photos. Every sign has recorded list of attributes describing these signs as type, size, shape, bar code number etc. The software uses Esri's ArcView application to review the location of each existing sign and allows to retrieve supporting details such as street names and distances between intersections.
- Reflectivity Data – Rodriguez utilized RoadVista 922 retroreflectometer to gather retroreflectivity values such as background and legend.
- GPS– Rodriguez utilized Trimble R8 GNSS GPS and Trimble TRS3 data collector using Virtual Reference System (VRS) to locate signs.
- Bar Code – Rodriguez utilized barcodesaffixed to the signs to identify the signs for future readings.
