Prof. Dr. Jaime Sanmartín Dr. Mauricio Chisvert Jean François Pace Project co-financed by  The European Commission. Directorate-General Transport and Energy (TREN-03-ST-S07.30828).  Universitat de València (20040272)  Generalitat Valenciana (GVACOMP2006-164/GVACOMP2007-176).

Project objectives  Main Objective:

www.uv.es/sau

 Design, validation, discussion and diffusion, at a European level, of the ‘best practices’ for the collection, processing and analysis of traffic accident data in urban areas.

[2]

 Operative objectives:

 Analysing in detail several Spanish cities of different size.  Detect the main problems & solutions in several EU cities.  Exchange experiences between experts from several EU countries.  The final result:

 A guide of advices and “best practices” in order to improve the systems that deal with the monitoring of traffic accidents in urban areas.

European Workshop

[6]

Objectives  Present the main results of the project.  Interchange experiences.  Propose advices and best practices to spread at the EU level:  Urban/local Polices.  Municipality RS authorities.  Regional/National RS authorities.

Participants  12 EU Countries.

The guide of best practices  Is mainly based on:

 A compilation of detected “best practices”.

www.uv.es/sau

 The exchange of experiences between several EU municipalities.

[7]

 The practical pilot experiences applied in several Spanish cities.  Several adapted recommendations from

the European Statistics Code of Practice.  To contribute to the development of local

tools:  More reliable and accurate knowledge, to the accident rate problems in each municipality.

Institutional context. Adequacy and homogenization of the collection criterions. Improvement in data entry procedures. Improvement of data collection questionnaire. Improvements in the computer system for data management and analysis.

6. Use of new technologies and introduction of the GIS. 7. Integration of the information through the linkage of several data sources

8. Training to the technical staff at any stages. 9. Data quality control. 10. Analysis and statistical production processes.

1. Institutional context

www.uv.es/sau

 Urban Accident Analysis Systems

[9]

 Urban Safety Management systems  Urban Mobility Management.  Collaboration of specialists and professionals.  Information exchange between agents, other municipalities and regional/central and European administrations.  Standardizing and homogenising procedures  optimizing local practices.  It is important:  Participation at European level for establish recommendations.  Events for experience exchange between urban polices

2. Collection criterions  The standardization and

www.uv.es/sau



[10]







homogenisation  comparisons at different levels and clarify an effectively use. Objective tools to detect and transfer the information. Also standardize the procedures to obtain the information, to the homogeneous understanding. Recommendations of specialists in accident data collection and processing. Manuals and training for the police forces must be developed, regarding the EU standardization recommendations.

3. Data entry procedures

www.uv.es/sau

 Improving the field work of the police:

[11]

Appropriate quantity of information  wide benefits.  The TA investigation, reconstruction and legal-administrative management procedure, being synchronised with the statistical practices.  Monitoring the evolution of victims at 30 days. It is much easier if carried out locally.  Increase the motivation of the police: Taking part in the design of the data collection system. Giving them feedback of statistical results. Participating in the intervention suggestions to improve the road safety.

4. Collection questionnaire

www.uv.es/sau

 Standardized collection protocol specifically designed for the urban areas.

[12]

 The questionnaire has to be simple, easy, fast to fill out.  Information entered electronically, avoiding the task duplication.  Specific fields in relation with urban elements, accident types and urban context.  Content manuals should exist to describe the criterions to fill out.  Information about the sequence of accident evens to define the accident type.  Systematic and periodic reviews.

5. Computer systems  Local or remote access .  Integrate all the procedures.  Computerize the

www.uv.es/sau

documentation.

[13]

 Automatic queries and

statistics.  Flexible system.  Adaptable to future.  Information in short periods

of time.

6. New technologies and the GIS systems  Expert or interactive system:

 Less missing data, errors, inconsistencies, time…  Geographical Information Systems.

www.uv.es/sau

 “In situ” accident data collection with PDA or laptop.

[14]

 Text, pictures, videos, sketches, maps, etc.

7. Integration of the information  Internal linking mechanisms with other databases available in the police

information system (only for statistical purposes):

www.uv.es/sau

 Traffic (density, volume…)

[15]

 Infrastructures (characteristics, signs…)  Vehicles (vehicle records)  Involved persons (offence or complaint records, driving licence records…), etc.  Unique identifier fields 

allow the linkage with external databases of the health system.

8. Training  Courses or training interventions in

the police action programmes:  Accident investigation.

www.uv.es/sau

 Information obtaining and coding

[16]

 Motivational and psychological aspects.  Basic statistical and reporting  Adapting continuous training to the

new conditions, technologies, methods and procedures.

9. Quality control  Optimized entry

and management.

 Less information

www.uv.es/sau

but reliable.

[17]

 Training and

incentive programmes.

 Analyses of missing

data and the errors.

10. Analysis and production of statistics  Specialized tools, procedures and

knowledge, adapted to its characteristics.

 Risk exposure indicators to

compare the information.

www.uv.es/sau

 Other mechanisms of analysis of

[18]

the accident rate patterns when exposure data are not available:  Spatial analysis.  GIS complementation.

 Interventions studies (before-after

or prospective).

 Public reports or statistical

documents.

 Periodic statistics with as little

delay as possible.

www.uv.es/sau

Finally…

[19]

 We need to pay more attention to:  Specificity of urban traffic accidents.  Quality of traffic accident information and data in urban zones.  Not only the information should be standardized but also the procedures to obtain it.  The role, training and motivation of urban polices.  We should do or impulse:  European studies about the current reality of urban traffic accident data quality.  An European manual for the urban polices.  European guidelines for training and helping the urban policemen.  New developments in database and statistical tools and procedures.
