A simple geometric model of the UXVs is first proposed, and the dynamics of the model is shown. The expected time of first collision is then formulated using the concept of mean free path from molecular dynamics. Monte-Carlo simulation is performed to verify the theory developed. The expected time of first collision is a function of the number of UXVs, the UXV speed and the sensor field of view (FOV) for a given operational area and vehicle size. Furthermore, the critical number of UXVs, above which collision can be deemed to occur instantly, is obtained.<\/jats:p>","DOI":"10.1017\/s0263574714001489","type":"journal-article","created":{"date-parts":[[2014,6,13]],"date-time":"2014-06-13T09:47:04Z","timestamp":1402652824000},"page":"347-360","source":"Crossref","is-referenced-by-count":2,"title":["Duration of collision-free motion of unmanned vehicles in a confined area"],"prefix":"10.1017","volume":"34","author":[{"given":"Qian","family":"Zhang","sequence":"first","affiliation":[]},{"given":"Gerard","family":"Leng","sequence":"additional","affiliation":[]},{"given":"Vengatesan","family":"Govindaraju","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2014,6,13]]},"reference":[{"key":"S0263574714001489_ref5","doi-asserted-by":"crossref","unstructured":"R.
