comment Road traffic database sample?
I couldn't say for the whole world, but I would start with looking at Open Street Map (OSM). Inrix (inrix.com) is a private company that provides traffic information. OpenTraffic (opentraffic.io) is an initiative to provide open real-time traffic information, similar to Google's traffic. I would start there.

Replacing the strings in the gdb column is not a difficult task, it can be performed in the Field Calculator.

Is there a reason why you are using v1.8 and not v2.8?

comment Is there a way to add x , y, z coordinate to the attribute table of polygon in ArcGIS 10.1?
Then you need to export the nodes as points, then calculate the x,y,z. If you have a unique ID for each polygon, that ID will come over when you export/convert the nodes to points. With that, you can relate the nodes x,y,z back to the polygons. Really there isn't any other way.

Looks like you need dissolve the neighbouring polygons first

I am not sure I am understanding your issue. According to your comment, you need the x,y,z centroid of the polygon. The process described above will provide you what you need. I would suggest that you edit your post to clarify your requirements, as well as provide a screen shot of our issue, so that others can visualize what you are asking.

comment Drawing 100x100 meter with 5 rows and columns grid centered on one point for multiple points?
Do you want a grid around the buffer, or a grid inside the buffer?

Would a buffer work? There is an option to make it flat not round, which would give a squared cell look.
