This prediction tool, termed the HIP (human injury predictor) code, was intended to:\n                    <jats:list list-type=\"simple\">\n                      <jats:list-item>\n                        <jats:label\/>\n                        <jats:p>\u2014\u2002assist the security services to encourage favourable crowd distributions and densities within scenarios of \u2018sensitivity\u2019;<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:label\/>\n                        <jats:p>\u2014\u2002provide guidance to security engineers concerning the most effective location for protection systems;<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:label\/>\n                        <jats:p>\u2014\u2002inform rescue services as to where, in the case of such an event, individuals with particular injuries will be located;<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:label\/>\n                        <jats:p>\u2014\u2002assist in training medical personnel concerning the scope and types of injuries that would be sustained as a consequence of a particular attack;<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:label\/>\n                        <jats:p>\u2014\u2002assist response planners in determining the types of medical specialists (burns, traumatic amputations, lungs, etc.) required and thus identify the appropriate hospitals to receive the various casualty types.<\/jats:p>\n                      <\/jats:list-item>\n                    <\/jats:list>\n                    This document describes the algorithms used in the development of this tool, together with the pertinent underpinning physical processes. From its rudimentary beginnings as a simple spreadsheet, the HIP code now has a graphical user interface (GUI) that allows three-dimensional visualization of results and intuitive scenario set-up. The code is underpinned by algorithms that predict the pressure and momentum outputs produced by PBIEDs within open and confined environments, as well as the trajectories of shrapnel deliberately placed within the device to increase injurious effects. Further logic has been implemented to transpose these weapon effects into forms of human injury depending on where individuals are located relative to the PBIED. Each crowd member is subdivided into representative body parts, each of which is assigned an abbreviated injury score after a particular calculation cycle. The injury levels of each affected body part are then summated and a triage state assigned for each individual crowd member based on the criteria specified within the \u2018injury scoring system\u2019. To attain a comprehensive picture of a particular event, it is important that a number of simulations, using what is substantively the same scenario, are undertaken with natural variation being applied to the crowd distributions and the PBIED output. Accurate mathematical representation of such complex phenomena is challenging, particularly as the code must be quick-running to be of use to the stakeholder community. In addition to discussing the background and motivation for the algorithm and GUI development, this document also discusses the steps taken to validate the tool and the plans for further functionality implementation.\n                  <\/jats:p>","DOI":"10.1098\/rstb.2010.0261","type":"journal-article","created":{"date-parts":[[2010,12,13]],"date-time":"2010-12-13T03:38:23Z","timestamp":1292211503000},"page":"127-143","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":26,"title":["The development of a quick-running prediction tool for the assessment of human injury owing to terrorist attack within crowded metropolitan environments"],"prefix":"10.1098","volume":"366","author":[{"given":"Daniel J.","family":"Pope","sequence":"first","affiliation":[{"name":"Physical Sciences Department, The Defence Science and Technology Laboratory, Porton Down, Salisbury SP4 0JQ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"175","published-online":{"date-parts":[[2011,1,27]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005373-198311000-00001"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(06)69896-6"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0734-743X(87)90029-7"},{"key":"e_1_3_3_5_2","volume-title":"Introduction to hydrocodes","author":"Zukas J.
