Base & future planning data by zone and more detailed census subdivisions.
Base & future networks.
Zoning and network plans.
This process is based around updating and existing zone system.
- Check transport model zone system compatibility with main data sources (for example, the census, but all relevant data sources should be identified) and with other relevant or linked transport models.
- Identify large zones (by level of activity or area, in base or future years); specifically consider 'sensitive' areas:
- regional and sub-regional central business districts,
- developing areas,
- activity centres (shopping, recreation etc)
- access to the central rail and bus stations,
- access to the rail network,
- future project corridors,
- access to important bottlenecks on the highway network, including representation of major turning movements.
- Review network connectivity of these transport zones.
- Decide whether any transport zones should be subdivided to improve assignment to the network or to reflect differential traffic growth patterns.
- Design the transport zonal subdivisions - which should recognise the requirement to obtain planning data for any subdivision.
- Include required transport network changes in Task 5.
- Produce base & forecast zonal planning data files to new transport zone system (in Task 3).
- Design sector aggregations for use in transport model calibration and validation (eg 5, 10 and 20 sectors).
- Code all surveys to the new transport zone system - specify process.
