Lesson 6: Transport Networks & Urban Accessibility
Demonstrating geographic understanding of urban spatial patterns, models, and processes.
🎯 Ngā Whāinga Akoranga | Learning Intentions
The role of transport infrastructure (motorways, passenger rail, busways, ferry lines) in extending urban boundaries and shaping commuter flow patterns.
Map peak travel times (isochrone maps), evaluate Northern Busway transit-oriented development, and analyse congestion bottlenecks.

🧠 1. Before Viewing (Activate & Predict)
How does investing in rapid transit (busways, rail) transform land values and housing density around station nodes?
👁️ 2. During Viewing (Watch With a Job)
- Watch for: Examine Isochrone travel-time maps comparing private vehicle vs public transport accessibility.
- Watch for: Analyse Transit-Oriented Development (TOD) high-density apartments built around train stations.
- Watch for: Evaluate the Harbour Bridge bottleneck and city-centre rail link (CRL) capacity expansion.
🗣️ 3. After Viewing & Kaiako Move (Process & Apply)
Kaiako Move: Discuss transport equity and emissions reduction targets connecting transport planning with climate change mitigation.
Immediate Task: Complete Section 6 of your Geography Portfolio: Isochrone Accessibility Mapping & Rapid Transit Evaluation.
⚡ Whakaoho | Do Now: The Station Changes the Land, Not Just the Trip
A fast bus or train station opens. Two minutes: name three things that change within 500 metres of it over the following decade.
Then say which of the three a landowner notices first. Today's isochrone maps will show you whether your instinct about accessibility matches what the network actually does.
📖 Activity 1: Draw the Isochrones, Then Find the Bottleneck
Shade the reachable city (13 min). From Britomart, shade everything reachable in 30 minutes at 8am — once by car, once by public transport. Use published journey-planner times, not estimates.
Find the gap (12 min). Where your two shaded areas differ most, mark it. That gap is the accessibility problem. Name the specific bottleneck producing it and one intervention that would genuinely close it, not just shift it.
📝 Activity 2: Level 2 Geography Portfolio Task & Merit/Excellence Scaffolding (20 mins)
Portfolio Section 6. Submit: (1) both isochrone maps drawn on one base map; (2) a statement of the largest car-against-transit accessibility gap, with the travel times that demonstrate it; (3) an evaluation of transit-oriented development around one busway station — what changed in land use, and who gained from the change.
🏫 Kaiako Planning & Pedagogy Notes
NCEA Level 2 Alignment: Direct preparation for Level 2 Geography (Demonstrate geographic understanding of an urban pattern). Emphasise integrating specific case study evidence and annotated map sketches for Merit/Excellence grades.
