Driving Side (?side=)

Speed Units

Motorway Lanes

Maximum Speed Limit 120 km/h

Minimum Speed Limit 70 km/h

Crawling Speed (Undertake Limit) 30 km/h

Max speed allowing inside passing. Set to 0 to strictly forbid undertaking.

Allow undertaking if empty lane in between Allow passing non-adjacent outer vehicles (e.g. L1 vs L3) only if all intermediate lanes are physically clear within safety buffers.

2. Lane Hogging Archetype (Red)

Hogger Proportion 25%

Cars that refuse to return to Lane 1 when empty.

Ultra Hogger Proportion 20%

% of hoggers camping in outermost fast lane.

Hogger Cruising Speed 95 km/h

3. Discipline & Overtaking Thresholds

Overtake Trigger Threshold 5.0 s

Vehicles only seek overtake if within collision thresold (or safety distance, whichever is less). Slide left for agressive.

Target Lane Car Approaching Buffer 5.0 s

Cars will not overtake if car approaching in target lane within this threshold. Left is more agressive.

Min Speed Advantage to Overtake 5 km/h

Cars only pull out if leader is slower, or can speed up to pass.

Post-Overtake Return Margin 5.0 s

Enforces staying ahead by this threshold before signaling & returning to slower lane(s) Left is more aggressive.

Stay-Out Gap (20s Rule) 20 s

Max gap between two overtakes not considered hogging.

Lane 2 Blocker Response Total: 100%

1. Sequential 2-Lane Overtake 60%

Move to Lane 2, pace until Lane 3 opens.

2. Queue Behind in Lane 1 25%

Stay in Lane 1, brake & queue behind blocker.

3. Undertake Directly (Ignore Ban) 15%

Stay in Lane 1, cruise past at desired speed.

              ● Overtake
              ● Queue
              ● Undertake
            

Sequential Overtake Pacing Timeout 30 s

Max time pacing in Lane 2 waiting for Lane 3 gap before aborting back to Lane 1.

4. Inflow, Lorries & Safety Headway

Traffic Inflow Rate 2400 veh/h

Articulated Lorry (HGV) Ratio 12%

Length 14.5m, capped at 90 km/h (56 mph). Strictly allowed ONLY in Lanes 1 and 2.

Minimum Safety Headway (T) 2.0 s

Headway Compliance Rating 85%

Lower compliance causes tailgating & phantom shockwaves.

5. Priority Emergency Vehicles Active

Spawn Interval 180 s (3.0 min)

Corridor entry interval into fastest lane.

Speed Capability Multiplier 150% (180 km/h)

Permitted speed limit multiplier for emergency vehicles.

Flashing Headlights Trigger 3.0 s

Time headway behind leader triggering high-beam pressure.

Emergency Corridor (Rettungsgasse)

Active

Under congestion (crawling speed), cars in fastest two lanes part to outer/inner edges to open a clear corridor for emergency vehicles.

Corridor Compliance 95%

Non-compliant drivers hold center until flashed by emergency lights (yield after 3-4s).

💥 Undertaking Collisions

0 Active

Base Collision Chance 2.5%

Probability adjacent car veers at 45° during inside pass.

Crawl Speed Risk Reduction 90% lower

Reduces risk when both cars travel ≤ crawling speed.

Hogger Inattention Multiplier +50% of base

Increases crash risk when vehicle being passed is a hogger.

Auto-Resolve Timeout 5.0 min (300s)

Clears incident if emergency crew cannot reach scene.

⚙️ Advanced Settings

Track-End Crash Buffer 60 m

Buffer zone before 2,000m corridor end prohibiting collisions to guarantee emergency vehicle clearance runway.
