Transport Fever 3 traffic and infrastructure planning
Quick answer
Transport Fever 3 confirms advanced traffic simulation with lane control, configurable lane connections and overtaking, plus modular infrastructure, highway ramps, overland trams and specialized terminals. Use the new controls to separate different kinds of bottlenecks instead of treating every queue as a vehicle shortage.
Diagnose before rebuilding
| Symptom | Inspect first | Relevant confirmed tool |
|---|---|---|
| Vehicles queue before a junction | Lane connections and turning conflicts | Individual lane control |
| A station approach is saturated | Platform, terminal and entrance capacity | Modular station design |
| Freight delays passenger services | Shared corridor and line priority | Transport priorities and line management |
| A transfer point fills repeatedly | Loading rules and intermediate storage | Warehouses and specialized terminals |
| Central access harms town quality | Noise and pollution layers | Data layers and visual displays |
| Road services block each other | Mode separation and corridor design | Tram lanes, ramps and configurable roads |
Separate flow, capacity and access
A crowded road can represent three different failures. Flow is poor when vehicles interfere at merges, turns or signals. Capacity is insufficient when a clean corridor is carrying more demand than it can process. Access is weak when stops or terminals force vehicles through the wrong streets. Each case needs a different response.
For a flow problem, simplify conflicting movements, adjust lane connections or separate modes before widening everything. For a capacity problem, increase useful frequency, vehicle size or corridor capacity while watching operating cost. For an access problem, move an entrance, add a connection or redesign the transfer so vehicles do not cross the same point unnecessarily.
Observe one full service cycle after each change. A queue that briefly forms and clears is different from one that grows without recovery. Check both directions, because fixing an inbound approach can shift the wait to an outbound junction.
Environmental overlays add another constraint. A central high-capacity route may solve travel time while increasing noise or pollution near sensitive districts. Compare the network benefit with the town effect and consider an outer corridor, cleaner mode or better interchange. The useful goal is dependable movement through the whole chain, not the highest number of vehicles on one segment.
A practical planning sequence
- Open the relevant data layer and locate the constraint: traffic hotspot, delivery problem, noise or pollution.
- Follow the affected route upstream to find the first place flow breaks down.
- Use lane connections or priority changes when the problem is conflict, not capacity.
- Expand a modular station or add a specialized terminal when the node itself is full.
- Recheck maintenance and environmental cost before adding more vehicles.
High passenger demand can produce both capacity and road-congestion problems. Adding buses or trams may increase frequency but also add vehicles to the same street. The better next action depends on whether the line, stop, approach or junction is the limiting entity.
