West Africa has extensive coastal ports and extraction railways built during the colonial era, but poor internal roads connecting regional markets to each other. This pattern is best explained by:
AGeographic barriers that make internal road construction technically difficult
BLow population density that reduced demand for internal transport
CColonial transport planning designed for resource extraction to coastal ports, not regional integration
DAfrican governments' post-independence preference for maritime trade
Colonial transport infrastructure was built to serve extraction — moving raw materials from the interior to coastal ports for export to Europe — not to connect African regions to each other. This legacy persists: West African goods often travel more cheaply to European ports than to neighboring African countries. The network encoded colonial priorities into physical geography, and that geography continues to inhibit regional integration decades after independence.
Question 2 Multiple Choice
In a hub-and-spoke transport network, nodes on the spokes (as opposed to the hub) are characterized by:
AGreater resilience because they are not choke points in the system
BDependence on the hub for connectivity and vulnerability if the hub is disrupted or controlled by a rival
CEqual connectivity to all other nodes in the network
DHigher traffic volume because they serve as feeder routes
Hub-and-spoke topology concentrates flows through a few major nodes, making those hubs disproportionately powerful. Spoke nodes depend on the hub for access to the broader network — if the hub is disrupted, congested, or controlled by a competing power, spoke connectivity collapses. This is why China's Belt and Road Initiative — routing new infrastructure through Chinese-controlled nodes — represents a strategic use of hub control as geopolitical leverage.
Question 3 True / False
A road built into a previously isolated valley can generate new economic demand and redirect development, not merely serve pre-existing demand.
TTrue
FFalse
Answer: True
Transport networks are not passive responders to existing demand — they actively shape it. A new road changes land values, makes previously inaccessible resources profitable, attracts settlement, and creates patterns of economic activity that then compound over time. Treating infrastructure as neutral supply responding to demand misses this generative power, which is precisely why infrastructure investment is such a potent political and economic tool.
Question 4 True / False
Transport networks are shaped primarily by technical engineering and geographic factors; their political dimensions are secondary concerns that do not fundamentally alter which connections get built.
TTrue
FFalse
Answer: False
The political economy of infrastructure is inseparable from its geography. The U.S. interstate highway system encoded military logistics priorities, automobile industry interests, and patterns of racial suburban development. Colonial railways encoded extraction priorities. China's Belt and Road encodes geopolitical influence. Infrastructure requires capital or sovereign authority to build, and those with capital or authority make choices about which corridors are worth connecting — systematically favoring already-profitable routes and particular political ends.
Question 5 Short Answer
Why must analysis of transport networks combine both physical/topological analysis and political economy analysis? What does each reveal that the other cannot?
Think about your answer, then reveal below.
Model answer: Physical analysis reveals topology — where hubs are, what the capacity constraints are, how connectivity is distributed — which determines what flows are possible and where bottlenecks arise. Political economy analysis reveals who built the network, who controls it, who benefits, and who is excluded — which explains why the topology looks the way it does and whose interests it serves. Neither alone is sufficient: topology without politics looks like neutral engineering; politics without topology lacks the mechanism showing how power is encoded in physical geography.
Infrastructure looks like engineering but is simultaneously a record of power. The network you inherit shapes the development options available to you. Understanding transport geography means asking both 'what connects where?' and 'why was that connection worth making to whom, under which historical pressures?'
