Fabrice Fussy, in charge of the Analysis and Research Unit of the National Monitoring Center of Delinquency in Transports (ONDT) • Fabrice.Fussy@developpement-durable.gouv.fr • 1st French-US Workshop on the Role of Public Transport in Creating Livable and Sustainable Communities • January 28, 2011 Mapping: a Tool for Analyzing Delinquency in Mass Transport Networks Direction générale des infrastructures, des transports et de la mer
Titre de la réunion Sommaire ONDT Specificities ISIS Database Observation, analysis, action : Mapping System
Titre de la réunion ONDT : the Genesis • 2001 : creation of a mission in charge of security and deliquency prevention • 2006 : creation of the National Monitoring Center of Security in Rail and Mass Transports (ONSTFC) • 2008 : creation of the National Monitoring Center of Delinquency in Transports (ONDT) • Strengthen and develop the fight against delinquency policy • Carry out the follow-up of the level of delinquency and assess the actions
Titre de la réunion ONDT Specificities ISIS Database Observation, analysis, action : Mapping System
Titre de la réunion Specificitiess • Specificities of the geographical approach of deliquency in transports : Static geography (stations,…) Spatial Dimension Dynamic geography (trains, streetcars…) Open spaces (stations, bus stops…) Social Dimension Closed spaces (underground…) Daily breathing (home-workplace) Time Dimension Seasons (school holidays…) • development of a tool adapated to these specificities
Titre de la réunion ONDT Specificities ISIS Database Observation, analysis, action : Mapping System
Titre de la réunion ISIS Database • Currently : • Gathers all the facts reported to the two main transport operators since 1999, that is, over a million acts • In a close future : • - integration of the acts reported to other transport operators • - integration of acts reported to the police
Titre de la réunion ONDT Specificities ISIS Database Observation, analysis, action : Mapping System
Titre de la réunion Mapping System • Know delinquency : • Illustrative mapping • Understand delinquency : • Strategic mapping • Anticipate delinquency : • Animated mapping
Titre de la réunion Illustrative mapping : Where ? When ? • Better know delinquence : • Accurately represent results indicators • Analyze the geographic distribution of delinquency acts • Find the concentration areas, the hot spots
Titre de la réunion Strategic mapping : why ? • Better understand delinquency : • Cross different types of indicators : result indicators and context indicators • Detect the interactions between delinquency and its environment • Use of a Geographic Information System
Titre de la réunion Strategic mapping : why ? • Allocate a specialisation to a territory : • Location ratio method The Location ratio of a type of act for a given site compares the contribution of this site for this type of act to the contribution of this site for all the acts recorded : overrepresentation Formula : Ci : number of acts of type i Ct : total number of acts n : analyzed spatial unit N : total territory analyzed • Ex : specialisation of French cities and departement in Ile-de-France
Titre de la réunion Animated mapping: what moment ? • Better anticipated delinquenc : • Represent jointly time and space • Observe breathing and seasonal effects • Detect delinquency transfers • Ex : Monthlty profil of metal robberies and • the evolution of Copper price
Titre de la réunion Recommendations • Promote the use of delinquency mapping at a strategic level • Disseminate a methodology guide for the mapping of delinquency in mass transports
