When you need a map, either paper or electronic, the cartography section is the go-to group. You know your map will be the most accurate, organized, and easy to understand because the science of geographic information system applications are behind every line, shape, and label.
If you are looking for traffic count data, the traffic group will help you find what you need. They spend their time collecting, processing, and publishing all types of data from short-term and permanent traffic counter information, including how many vehicles travel on a section of road, how fast the vehicles are going, what types of vehicles travel that section, and how much the vehicles weigh. For number crunchers, this data is available in tabular listings or, if you prefer the information in a visual way, the group produces maps and charts using the data.
