Our initial investigation will be at crash rates at intersections and roadway segments.

Given the following determine the crash rate at the intersection.

AADT rates: NB app: $6200$; SB app: $7200$; EB app: $9500$; WB app: $10,500$

Ave number of crashes over the last three years: $25$

Give the following, determine the crash rate at the roadway section.

AADT: $12,500$ vehicles

Length of segment: $3\mathrm{.}75$ miles

Average number crashes over the last three years: $17$

Using the following formula, predict the number of crashes for a rural $4-$leg intersection with minor$-$road STOP control. ADT$1=6500$ veh; ADT $2$: $3700$ veh

$N_p=$exp$(-8\mathrm{.}69+1\mathrm{.}65lnAD{T}_1+0\mathrm{.}87lnAD{T}_2)$
