    Trip generation studies for TND (traditional neighborhood development)

    Current trip generation models an statistics, especially the ITE Trip Generation Manual, are based on single uses in vehicle-oriented suburban environments, with a heavy bias towards California and sunbelt states, although that may change with the 9th Edition. The following is some links that I've collected in doing research on trip generation for NU/TND development.

    Traditional Neighborhood Development Trip Generation Study

    From the executive summary:

    In terms of traveler behavior this study finds no statistically significant difference between the total trips made by households in the Southern Village TND and the comparable conventional developments. However, TND households substituted driving trips with alternative modes, i.e., the automobile trip generation rate for the TND was significantly lower (by 1.25 trips per day per household) than conventional neighborhoods. In addition, empirical evidence suggests that TND
    households have:

    • Lower vehicle miles traveled—on average, the TND single-family households travel 18 miles less per day.
    • Higher share of alternative modes—in the TND, 78.4 percent of the trips were by personal vehicle compared with 89.9 percent in the conventional neighborhoods.
    • Lower external trips—on average, the TND households made 1.53 fewer external trips per day.

    Doesn't Cervero have a newer paper in JAPA with updated (albeit less useful for advocates) numbers? Can't find a non-paywalled paper...
