Perspectives on Urban Form, Road Classification and Access Management
Hein J. Stander, AECOM
OUTLINE:
- Background
- Spacing Higher Order Roads
- Comparison International Cities
- Access Spacing and Real World Situation
- Application of AM in Practice
- Conclusions
APPLICATION AM IN PRACTICE:
Approach proposed for practical application:
- Develop/adopt AM policy
- Classify road network
- Make road classification available to land owners/developers
- Refuse rezoning requiring access which in contradiction to policy
- Don’t allow intersection control (signals) at improper spacings – use marginal/partial access
- Develop arterial management plans indicating planning of accesses
- Retrofit where access conditions are poor
- Gradually upgrade mobility wherever possible
- Employ traffic calming on access streets to encourage use of mobility routes
CONCLUSIONS:
- Actual spacing of higher order routes is close to “ideal” spacing
- Standards for spacing of higher order routes appear to be realistic
- Characteristics of road classes differ worldwide
- Practical situations exist which cannot be served by standards/guidelines that have been developed
- Only solution is decisions “based on policy”
- Development of arterial (access) management plans important to provide guidance to land owners/developers
