Where should I spend my money?

Waterview connection Cost: $2.912m Benefit: $3.370m User benefits $28m Wider benefits $0 Revenue BCR: 1.15:1

School Travel Plans Cost: $1.5m Benefit: “Probably positive” BCR: ?? Town centre enhancement Cost: $15m Benefits: “It’s a good thing to do” BCR: ??

Where should I spend my money?

slide-6
SLIDE 6

How?

  • Cost savings
  • Stated preference
  • Hedonic pricing
  • Secondary benefits
slide-7
SLIDE 7

Measuring quality

  • Can we measure

walkability?

  • Quality audits (PERS,

community street review)

  • Numerical

measurements, e.g. layout (accessibility, legibility), access to green space

slide-8
SLIDE 8

Climate change

  • Mode shift
  • Embedded emissions
  • Adaptation (drainage,

shade)

slide-9
SLIDE 9

Economic growth

  • Local connectivity
  • Clustering
  • Local property prices
  • Retail performance
slide-10
SLIDE 10

Equality of opportunity

Safety, security and health

  • Road safety
  • Physical activity
  • Mental health
  • Air quality
  • Crime

Prioritising investment:

The pedestrian barriers project

Background

Potential demand Quality of crossing provision

Generally positive relationship between demand and provision ‘High demand & poor facilities’ ‘Good facilities & low demand’

Demand and facilities

Quality of crossings

  • Generalised journey

time:

  • Horizontal deflection
  • Vertical deflection
  • Delays

Demand forecasting:

A recent example

slide-25

Background

  • Opportunity Area:
  • Battersea Power

Station

  • US embassy
  • High density mixed

use developments

  • Green space
  • Transport network

upgrades

Movement forecasting

Our approach:

  • Link to strategic
  • utputs
  • Public realm
  • Layout variables
  • Activity and movement

Applications

  • Scenario testing
  • Capacity
  • Crossing design
  • Security
  • Retail
  • Business case inputs

Improving routes:

What works for walking?

5 recommendations

  • 1. Getting the basics right
  • 2. Personal security
  • 3. Safe and direct routes
  • 4. Dwell and rest spaces
  • 5. Capacity

  • 3. Safe and direct routes
slide-37
SLIDE 37
  • 3. Safe and direct routes –

guard rail

slide-38
SLIDE 38
  • 3. Safe and direct routes -

crossings

slide-39
SLIDE 39
  • 4. Dwell and rest spaces
slide-40
SLIDE 40
  • 4. Dwell and rest spaces
  • Natural meeting

points

  • Next to main flow
  • Facing main flow /

activity

  • Protected back
  • Adaptable space
slide-41
SLIDE 41
  • 5. Capacity –

vehicular vs. pedestrian

Similar:

  • Finite capacity
  • Movement flows

and stationary

  • Queues can

block other flows Different:

  • Not always linear
  • Waiting to cross
  • Role of place

functions

Objective

“Establishing a set of international guidelines for the collection, analysis and dissemination

  • f quantitative and qualitative techniques for

measuring walking.”
