  Features – what the proposed design involves.

  • Install a new raised speed platform designed to accommodate boat trailers with coloured road marking of the 40km/h speed limit and landscaped raised islands either side on Cambridge Parade, to the west of the intersection.
  • Replace the Stop signs and line marking with Give Way signs and line marking on Melville Terrace and Arnold Street at the intersection with Cambridge Parade.
  • Reconstruct and extend the kerb buildouts, install new sections of footpath and a new kerb ramp on the northwest and northeast corners of Melville Terrace and Cambridge Parade.
  • Install minor landscaping improvements on the northwest corner of Cambridge Parade and Melville Terrace.
  • Reconstruct and extend existing concrete traffic islands on Melville Terrace.
  • Introduce new no stopping lines on the northwest and northeast corner of Cambridge Parade and Melville Terrace, and on the southern side of the raised speed platform on Cambridge Parade.
  • Introduce 30 formal on-street parking spaces along Cambridge Parade to the intersection with Stratton Terrace.
  • Remove 5 informal on-street parking spaces along Cambridge Parade and install a new traffic island on the northeast corner of Cambridge Parade and Melville Terrace.

  Benefits – why we are proposing the features of this design.

  • Improved safety for people walking and riding by achieving better motorist compliance of the 40km/h speed zone by introducing new coloured road markings and installing a raised speed platform designed to accommodate boat trailers.
  • Increased connectivity and safety for all road users by reconstructing and extending the kerb buildouts on the northwest and northeast corners of Cambridge Parade and Melville Terrace and installing a new traffic island on Melville Terrace, reducing the potential for pedestrian and motorist conflict.
  • Enhanced visibility for all road users by installing a new traffic island on the northeast corner of Cambridge Parade and Melville Terrace, new no stopping lines and removing select on-street informal car parking spaces.

  Considerations – things to consider about this proposed design.

  • Less parking loss is required in Design A to achieve desired sightlines for road users when exiting Arnold Street or Melville Terrace into Cambridge Parade because the raised speed platform achieves better motorist compliance of the 40km/h speed limit.
  • The raised speed platform has been designed to accommodate boat trailers.
  • On the southern side of the raised speed platform, the design allows for sufficient bicycle bypass space to assist slower moving uphill cyclists to get past these facilities without having to use the traffic lane.
  • It has been established that the use of Stop signs in locations with adequate sight distance do not provide additional safety benefits, can lead to a loss of ‘credibility’ and their effectiveness in general are compromised.

  Features – what the proposed design involves.

  • Introduce new coloured road markings for the 40km/h speed zone with a garden bed island to the north and new traffic island to the south on Cambridge Parade, west of the intersection.
  • Replace the Stop signs and line marking with Give Way signs and line marking on Melville Terrace and Arnold Street at the intersection with Cambridge Parade.
  • Reconstruct and extend the kerb buildouts, install new sections of footpath and a new kerb ramp on the northwest and northeast corners of Melville Terrace and Cambridge Parade.
  • Install minor landscaping improvements on the northwest corner of Cambridge Parade and Melville Terrace.
  • Reconstruct and extend existing concrete traffic islands on Melville Terrace.
  • Introduce new no stopping lines on the northwest and northeast corner of Cambridge Parade and Melville Terrace, and on the southern side of the raised speed platform on Cambridge Parade.
  • Introduce 30 formal on-street parking spaces along Cambridge Parade to the intersection with Stratton Terrace.
  • Remove 8 informal on-street parking spaces along Cambridge Parade and install a new traffic island on the northeast corner of Cambridge Parade and Melville Terrace.

  Benefits – why we are proposing the features of this design.

  • Improved safety for people walking and riding by promoting motorist compliance of the 40km/h speed zone by introducing new coloured road markings.
  • Increased connectivity and safety for all road users by reconstructing and extending the kerb buildouts on the northwest and northeast corners of Cambridge Parade and Melville Terrace and installing a new traffic island on Melville Terrace, reducing the potential for pedestrian and motorist conflict.
  • Enhanced visibility for all road users by installing a new traffic island on the northeast corner of Cambridge Parade and Melville Terrace, new no stopping lines and removing select on-street informal car parking spaces.

  Considerations – things to consider about this proposed design.

  • More parking loss is required in Design B to achieve desired sightlines for road users when exiting Arnold Street or Melville Terrace into Cambridge Parade because coloured road markings can only promote adherence and does not have the same level of compliance as a speed platform to get motorists to slow down to 40km/h.
  • Design B does not include a physical project feature that can promote speed compliance.
  • The bicycle bypass space defined by the new traffic island on the southern side of the new coloured road markings allows for slower moving uphill to ger past these facilities without having to use the traffic lane.
  • It has been established that the use of Stop signs in locations with adequate sight distance do not provide additional safety benefits, can lead to a loss of ‘credibility’ and their effectiveness in general are compromised.
