“…In recent years, the increasing volume of vessel traffic volume and rising navigation density have resulted in an increasing number of vessel collision accidents in navigation channels [6]. Navigation safety issues in navigation channels have attracted extensive attention from researchers and practitioners [7][8][9][10]. To strengthen safety in navigation channels, the International Maritime Organization (IMO) has established a traffic separation scheme to prevent collisions and avoid accidents [11,12].…”

A rising volume of vessel traffic increases navigation density, which leads to an increasing risk of vessel collisions in navigation channels. Navigation safety issues have been widely studied with the aim of reducing such collisions. Intelligent navigation channels, which involve deploying remote-sensing radars on buoys, are an effective method of tackling vessel collisions. This paper investigates the problem of radar deployment in navigation channels, aiming to expand the radar coverage area and effectively detect vessel locations. A mixed-integer linear programming model is formulated to determine the optimal deployment of radars in navigation channels under a given budget, where radars with different coverage radii and different types of buoys are introduced. Then, sensitivity analyses involving the impacts of budgets, the coverage radii of the radars, the distance between adjacent discrete locations, and the distribution of the existing buoys on the radar deployment plan are conducted. The computational results indicate that the coverage ratio of the navigation channel can be improved by reasonably deploying the different types of radars on the existing and new buoys under a given budget.
