                Safety Assessment of Interchange Spacing on Urban Freeways: Enhanced Models
Publication Information
              Publication External Link:Safety Assessment of Interchange Spacing on Urban Freeways: Enhanced Models
                          Abstract:The problem of interchange spacing is mostly studied from an operational perspective. The decision to build a new interchange within existing freeway spacing is determined by access needs and guidelines. The safety impact of inserting a new interchange is yet unknown although it is essential when conducting cost-benefit analysis or simply a safety assessment. In this paper, crash prediction models for interchange spacing are derived using data from California and Washington states. The models are then used to quantify the crash sensitivity to interchange spacing.
