Summary of Recommended Standardized Procedures and Guidelines 31 2.5.4 C-5: Coding Complex Variables This item is concerned with how to code the responses to certain types of questions involving categories that may vary from survey to survey, depending on the level of detail required for a specific survey. Among the questions that fit within this item are income and activity. There are a number of complex variables where it would be useful to adopt a consistent pro- cedure for the values used to report the data. This would enhance comparability of surveys and remove potential ambiguities. It is also contingent on standardizing response categories to cer- tain questions, as discussed in Section 2.1.2. These proposed procedures should be developed not only for any appropriate questions in the minimum question specifications, but also for additional questions that may be used in many travel surveys. Further discussion may be found in Section 8.4 of the Technical Appendix. It is recommended that 1. Multi-digit codes for complex variables, similar to the codes shown in Table 7, be adopted in all future travel surveys. For income, the codes specified in Table 7 are recommended to be used for consistency across surveys. 2. The activity categories shown in Table 8 be adopted for general use in future travel surveys. These categories are based on more or less commonly used trip-purpose categories, but provide for a much more detailed breakdown into activity types that can be used in activ- ity surveys. Table 7.
