Traffic and Parking GenerationThe impact on development
AITPM National Conference 2014Paul Morris
Development Assessment
• Parking Demands• Off-street supply• On-Street impacts• Shared/Compatible Uses• Multiple-use discounts
• Development Plan• Specific rates• Generic definitions
• Empirical Data• SA Guides• RTA Guide• SA Surveys• GTA Database
Development Assessment
• Traffic generation• Internal operation• Access• External impacts
• Development Plans• Objectives• Principles
• Empirical Data• RTA Guide• SA Surveys• GTA Database
Access – a matter of degrees
• Linked to traffic generation• Appropriate Access?
• Unsignalised or signalised• Restricted turning movements• Use of existing local streets• Left turn auxiliary lanes
• Warrants• Left turn lanes
Access – a matter of degrees
• Austroads Guides
Determining the Need for Auxiliary LanesThe need for deceleration turn lanes cannot be stated definitively in all instances because of the many factors to be considered, such as speeds, traffic volumes, capacity, type of road, service provided, traffic control and crash history.
Guide to Road Design – Part 4A: Unsignalised and Signalised Intersections
Access – a matter of degrees

Access – a matter of degrees
• External Infrastructure Costs• Short Taper - $30K• Standard Deceleration Lane - $150K• Extra costs for land acquisition, services, design, etc
• Developments are marginal• Use appropriate analysis• Justify needs not just broad warrant
Parking – The BIG Issue
• Parking Demands• Off-street supply• On-Street impacts• Shared/Compatible Uses• Multiple-use discounts
• Development Plan

They should
build more parking.....
.
Only 3.9 per 100sqm...WOW
Hmmm... 130 spaces
OMG...$650K to build
RUK.... $3.7m..!!
WOW....85 spaces available
$2.5m
Conclusions
• Development Plans• Review parking rates• Lower shopping centre rates
• Traffic Warrants• Review the use of warrants• Consider the actual need from analysis
• Consider the cost• Impact on feasibility
