Italian speed bumps installed since 1990 are often ineffective at reducing vehicle speeds. Studies show many drivers exceed speed limits, indicating a need for better traffic calming measures.

Area of Science:

  • Traffic Engineering
  • Urban Planning
  • Road Safety

Background:

  • Italy implemented speed bumps in 1990 to reduce pedestrian fatalities from speeding vehicles.
  • Unlike other countries, Italian speed bump installations lack systematic scientific evaluation.
  • Existing Italian speed bump designs may cause user issues and are less effective than speed humps or cushions.

Purpose of the Study:

  • To assess the effectiveness of 23 speed bump installations in Cagliari, Italy.
  • To analyze vehicle speed reduction capabilities of existing speed bumps.
  • To compare speed profiles before, at, and after speed bumps and crosswalks.

Main Methods:

  • Conducted speed analysis at 23 speed bump sites in Cagliari.
  • Measured vehicle speeds at bump locations, protected crosswalks, and street sections away from bumps.

  • Calculated speed profiles at specific sites to observe driver behavior changes.

    • Main Results:

    • In one-third of cases, the 85th percentile speed at bumps exceeded the 50 km/h limit.
    • An equal proportion of vehicles traveled near the speed limit (45-50 km/h).
    • No significant speed differences were found between free, bump, and crosswalk sections; speed reduction effect was limited to 20-30m.

    Conclusions:

    • Current Italian speed bumps are largely ineffective in significantly reducing vehicle speeds.
    • The limited spatial range of speed reduction suggests current designs are inadequate.
    • More effective traffic calming devices like humps or cushions, or integrated strategies, are recommended.
