This paper empirically analyzes the characteristics and conditions of roads that affect roadkills of water deer in Korea, and suggests strategies for the reduction of such roadkills. A total of 133 water deer roadkills that occurred during one year from May 1, 2018 to April 30, 2019 are included in the analysis. The Kaplan-Meier estimator and survival regression are applied as analytic tools. According to the empirical results, it seems that the probability of water deer-vehicle collisions is significantly lower on sites with more lighting facilities, less traffic, fewer lanes, a flat road or uphill slope, longer distance from a water source, more urbanized areas, or a speed reduction sign. The results are largely similar when the error term assumes a Weibull distribution rather than an exponential distribution, suggesting that the analysis results are robust.
