1 The necessity to evaluate road safety improvements

2 The necessity to evaluate road safety improvements Evaluation of road safety improvements Study of the road traffic situation in Toulouse The small roundabouts Muret main street Conclusion

3 Evaluation of road safety improvements Why evaluating? To give a feedback to the financers on the improvements made To be able to optimise the action and to repeat it elsewhere To improve the action and to have a possibility to immediately correct in case it does not have the expected impacts To improve the national but also local road safety knowledge, as to say adapted to the local situation

4 Evaluation of road safety improvements What to evaluate? The construction of a roundabout A priority policy A small roundabout To follow the effects of the construction from 6 months to 3 years The attentiveness of the police to produce truthful accidents reports, An instruction of local administration officers A communication campaign A bicycle promotion policy A safety promotion policy,

5 Evaluation of road safety improvements How? After having defined the objectives, one has to define the criteria and measurable indicators to qualify and quantify the results in relation to each objective Each objective should be accompanied by at least one indicator

6 Situation study of the streets of Toulouse (5 years) Principal roads (inter-)neighbourhood roads Destination roads Streets of the (hyper) centre

7 Situation study of the streets of Toulouse (5 years) Nr. of accidents % of total accidents Total length in km % of the total length Nr. of accidents per Km Principal streets (inter) neighbourhood streets Streets of (hyper) centre Small destination streets Total Urban highway % of the accidents take place at 17 % of the network (principal roads) 62% of the network (small destination streets) generate 13% of the accidents

8 Situation study of the streets of Toulouse (5 years) Constructed roundabouts Other roundabouts

9 Situation study of the streets of Toulouse (5 years) A road hierarchy permits a prioritisation of the actions

11 small roundabouts 1st evaluation November 2001 (45 Small roundabouts) A significant reduction of 72.3% of accidents with physical damage before/ after realisation of 72,3 % Before the construction 72 registered accidents on a total of 2621 months After the construction 14 registered accidents on a total of 1838 months 2nd evaluation June 2006 (98 Small roundabouts) A significant reduction of 77.1% of accidents with physical damage before/ after realisation of 77,1 % Before the construction 114 registered accidents on a total of 9149 months After the construction 16 registered accidents on a total of 5619 months

17 Muret Main street Section Croix de Pierre Rte de Seysses Physical accidents from 1996 to 2000 (5 years) 4 dead, 5 heavily injured, 57 lightly injured

18 Muret Main street Section Croix de Pierre Rte de Seysses Objectives of the reconstruction Improve the security of all road users Re-qualification of the road space

20 Muret main street Croix de Pierre Before After Metal poles to avoid illegal parking

21 Muret main street Before the construction (107 months) 94 accidents 5 Dead, 9 HI and 96 LI After the construction (29 months) 12 accidents 0 Dead, 0 HI et 13 LI Reduction of the accidents - 52,9 % Very SIGNIFICANT REDUCTION OF THE SERIOUSNESS 5 Dead and 9 HI Before 0 After

22 Conclusion The implementation, realisation, following and evaluation of a road safety policy in Toulouse permit a significant reduction of the physical accidents in the urban area.
