- •
Pedestrian and bicycle crashes based on traffic analysis zones have been analyzed.
- •
The viability of dual-state models for macro-level crash analysis is evaluated.
- •
Spatial independent variables are introduced for spatial spillover effects.
- •
Many variables in targeted and neighboring traffic analysis zones are significant.
- •
Marginal effects are computed to assess the effect of significant factors.
