3 Traffic volume Development traffic Network capacity Meeting Demand?

4 Background growth Network capacity Development traffic Traffic demand 10 years Required capacity 10 years after full opening of the development The Traditional approach

5 1 - Build new capacity 2 - Technology Improvements 3 - Access Management 4 - Impact Avoidance Four basic methods of accommodating growing demand:-

6 Background growth Network capacity Development traffic Traffic demand 10 years The Traditional approach

7 Background growth Network capacity Development traffic Traffic volume The Traditional approach

8 Background growth Network capacity Traffic congestion / unsatisfied demand Many network capacity improvements are not feasible

9 Minimise new traffic generation Reduce / reverse background growth Constrain overall traffic within manageable, acceptable limits Where capacity headroom is very limited, we need to manage demand:-

19 The Trip Credit approach

21 Trip Credit interventions: Minimise impacts from new developmentMinimise impacts from new development Create headroom from neighbouring existing developmentsCreate headroom from neighbouring existing developments Aim to achieve traffic neutrality (or as near as possible)Aim to achieve traffic neutrality (or as near as possible)

22 New Employment Existing Employment Existing Housing Existing Employment

23 A Real Working Example…

24 New development with 215 new employees Estimated 182 two way trips at am peak Estimated 182 two way trips at am peak In-boundary travel plan measures reduce trips to 136 (25% trip saving) In-boundary travel plan measures reduce trips to 136 (25% trip saving) Area wide travel plan measures save a further 170 trips Area wide travel plan measures save a further 170 trips Net trips from site -34! Net trips from site -34!
