Positive report on reduced speed limit on Paris ring road

Just one year after the introduction of the reduction of the speed limit from 80 km/h to 70 km/h on the Paris ring road, reports from the City Hall paint a positive picture of the results of this controversial measure. Accidents on the ring road are said to have reduced by 15.5 per cent, from 742 in 2013 to 627 in 2014, while the number of injuries has reduced from 908 in 2013 to 776 in 2014.

Just one year after the introduction of the reduction of the speed limit from 80 km/h to 70 km/h on the Paris ring road, reports from the City Hall paint a positive picture of the results of this controversial measure.

Accidents on the ring road are said to have reduced by 15.5 per cent, from 742 in 2013 to 627 in 2014, while the number of injuries has reduced from 908 in 2013 to 776 in 2014.

Ironically, the reduced speed limit has resulted in an increase in the morning average speed from 32.6 km/h in 2013 to 38.4 km/h in 2014, while the average speed in the evening has increased from 30.3 km/h in 2013 to 33.9 km/h in 2014. These results are explained by ‘reducing the accordion effect’ and have increased journey time savings by 15 per cent in the morning and five per cent in the evening.

The decrease in the speed limit also reduced noise by 1.2 dBA at night and by 0.5 dBA during the day, which corresponds to decreases in traffic of 25 per cent and 10 per cent.

According to Christophe Najdovski of Europe Ecologie Les Vert, the results should open the debate on testing a speed limit of 50km/h on the ring road.

    Transport Infrastructure Ireland (TII) is working with the4 Irish police force, An Garda Síochána, on the installation of Ireland’s first average speed camera enforcement system, which will be deployed in the Dublin Port Tunnel. Opened in 2006, the 4.5 km tunnel forms part of the M50 C-Ring road around Dublin City. Traffic levels through the tunnel have increased by 40 per cent over the last five years and as a result there is statistically, an increase in the potential for collisions and accidents.

  • Danish study shows higher speed limits are safer
    February 25, 2014
    A two-year experiment by the Danish road directorate shows accidents have fallen on single-carriageway rural roads and motorways where the speed limit was raised. Since the speed limit on some stretches of two-way rural roads was increased from 80 to 90 km/h, accidents have decreased due to a reduction in the speed differential between the slowest and fastest cars, resulting in less overtaking. The slowest drivers have increased their speeds, but the fastest 15 per cent drive one km/h slower on average

    Hard shoulder running has become the UK’s default response to increasing motorway capacity as Colin Sowman reports. Facing a predicted 46% increase in traffic levels by 2040 and the current economic recovery leading to more people travelling to, from and for work leaves the UK government under short- and long-term pressure to increase the capacity on the main motorway network. Particular sections of motorways are already experiencing repeated, sometimes tidal, congestion and both tight Treasury limits and t
