Only the number of collision candidates is calculated.<br /> <br /> This test case calculates the number of Crossing collisions per year.<br /> <br /> == The Scenario ==<br /> <br /> [[Image:20090405 Test Case Crossing Collision Fig1.jpg]]<br /> <br /> To calculate this scenario with the IWRAP tool, do the following steps:<br /> <br /> * Define leg;<br /> * define traffic distribution in each direction;<br /> * define causation factors;<br /> * define number of ships in each direction;<br /> * run the job and read results.<br /> <br /> <br /> == Hand calculation of the Crossing Collision Scenario ==<br /> <br /> The geometric number of crossing collisions candidates for crossing waterways can similarly to Eq. (4.2) be expressed as:<br /> <br /> [[Image:20090405 Test Case Crossing Collision Fig3.jpg]]<br /> <br /> [[Image:20090405 Test Case Crossing Collision Fig2.jpg]]<br /> <br /> <br /> This result is equal to the result calculated by IWRAP.<br /> <br /> <br /> {{Theory_Source_PFH}}<br /> [[Category:Theory]]<br /> [[Category:Test Cases]]</div>
