CHAPTER 3: KEY ITS DATA ELEMENTS FOR GOVERNMENT REPORTING SYSTEMS
3.2 KEY ITS DATA TYPES
The matching exercise revealed that the current ITS data dictionaries (TMDD and P1512 and ATIS Data Dictionaries) have the potential for providing a relatively small fraction of data to traditional government reporting systems. However, a few key data items that are critical to many government reporting systems have counterparts in the ITS realm (Table 3.1). As part of traditional systems, these data are expensive to collect (traffic data), difficult to obtain/verify (hazmat and carrier identification), or both. Using data from ITS sources will substantially reduce these problems.
