Abstract
To evaluate the effectiveness of a road safety measure, the number of accidents before and after the measure, classified in r categories, ar e observed on s sites, with theta(k) the effect of the safety measure for the site k (k = 1, 2, . . ., s). We propose a statistic to test th e hypothesis H0:theta1 = theta2 = . . . = theta(s) = theta. Its asympt otic distribution is given under certain conditions.
