Table 2 Advantages and Disadvantages of Mandatory and Advisory Measures

Advantages Disadvantages
Mandatory
  • Provide maximum benefit and encouragement to NMV users, such as physical segregation (protection)
  • Require regulations, which may need public consultations, and therefore take time to implement
  • Requires enforcement resources to ensure compliance
  • Can be more difficult to design due to higher level of restriction on access by other vehicles
Advisory
  • Do not require formal regulations
  • Can be introduced quickly
  • Usually relatively cheap
  • Do not require enforcement
  • Such measures are usually only indicative, so may not always be effective
