Abstract |
The COMMUTER Model employs a simplified logit modeling process (called pivot point) that relies on locally derived coefficients to evaluate the influence of alternative measures on travel behavior. The coefficients are derived from observed travel behavior using standard survey techniques, statistical analysis, and modeling methods. Coefficients that have not been derived from observed travel behavior (such as composite measures or transferred coefficients) are not included as they could bias the average values. The fact that the coefficients are all derived using similar statistical methods explains why the coefficients are reasonably similar across the country. A review of the coefficients indicates that while they are relatively consistent across the country, there is enough variation in values between cities that it is essential that users understand the use of these coefficients. This report provides the user with this background information. |
