5.1.3. Program Level

At the program level of decision-making, the critical dimensions are accuracy, consistency, and completeness from the syntactic category; accessibility and timeliness from the empiric category; and ambiguity from the semantic category. No dimensions from the pragmatic category are crucial for program-level decision-making. Program-level decisionmaking deals with the programming of the projects. For making decisions at the program level, the decision-makers focus on the form and structure of data, establishing means of communication and data handling and information on the data. The pragmatic category dimensions deal with the knowledge generated from the data, which is not much focused on decision-making at the program level.

## 5.1.4. Project Selection Level

The project selection level addresses project selection, safety improvement, and traffic control studies at the regional office level. From the syntactic category, the critical dimensions are accuracy, consistency, completeness, structure, and integrity. From the empiric category, the critical dimension is only accessibility. From the semantic category, the critical dimensions are ambiguity and believability. From the pragmatic category, the dimension value is only critical in analysing the questionnaire data.
