DEVELOPMENT OF SPATIAL NETWORK MODEL

CD = 100 CD = 300

PROXY FOR REAL-WORLD NODAL LAYOUT

EXPONENTIAL SYNTHETIC NETWORKS

CD = 100 CD = 200 CD = 300

TOPOLOGICAL HAZARD TOLERANCE

Assessed by subjecting the networks to:

Random hazardDegree attack strategy

SPATIAL HAZARD TOLERANCE

Assessed by using a ‘central attack’ spatial hazard Remove nodes in order of their distance from the centre of the

network

SPATIAL HAZARD TOLERANCE

SPATIAL HAZARD TOLERANCE

CONCLUSION

To date little work has been done on spatially distributed networks

Space has a small but important effect on the degree distribution of a network and can have a significant effect on the hazard tolerance

We have developed a network model which is capable of capturing the growth of infrastructure systems in terms of both their network architecture and geographical distribution

This can be used to form an assessment of their hazard tolerance to spatial hazards
