Target Product: Waze Navigation

Feature Name: Tram Trail Project (TTP) / Light Rail Crossing & Shared Lane Safety Alerts

Target Platforms: iOS, Android, Android Auto, Apple CarPlay

1. Executive Summary As urban transportation evolves, light rail and tram systems increasingly share roadway space with private motor vehicles. Unregulated rail crossings and tracks embedded directly in driving lanes present significant hazards for drivers.

The Tram Trail Project (TTP) introduces dynamic, context-aware audio-visual notifications into Waze. By focusing strictly on actionable 150-meter proximity warnings and dedicated Shared Lane Modes, TTP drastically reduces collision risks while preventing driver alert fatigue.

1. Problem Statement High Collision & Skid Risks: Trams require substantially longer stopping distances than cars and cannot steer away from obstacles. Furthermore, wet steel tracks embedded in asphalt create severe skid hazards for motor vehicles.

Driver Blind Spots: Urban intersections with light rail frequently lack active signal gates, leaving drivers vulnerable when making turns across tracks.

Alert Fatigue in Navigation Apps: Overly frequent or distant alerts (e.g., warning 500 meters in advance in dense city centers) lead drivers to ignore navigation prompts altogether.

1. Key Feature Capabilities A. Precision Proximity Alert (150m Critical Zone) Actionable Timing: Omits redundant 500m pre-warnings in dense urban grids, triggering alerts precisely 150 meters before a rail intersection.

Visual Banner: High-visibility yellow/slate warning banner featuring a custom tram icon and distance counter.

Audio Signature: Distinct, non-intrusive chime combined with a concise voice prompt ("Caution, tram crossing in 150 meters").

B. Shared Lane Mode (Tracks in Roadway)
Automatic Detection: Identifies road segments where tram tracks run flush with vehicular lanes.

Contextual Caution: Displays an active banner reminding drivers to maintain increased trailing distance behind trams and exercise caution during wet weather due to decreased tire traction.

C. Seamless Infotainment Integration
Fully adapted layout designs for Android Auto (Coolwalk) and Apple CarPlay, maintaining native UI guidelines and zero-clutter principles.

1. User Experience & Interaction Flow Approach Phase: Vehicle enters 150m radius of an active or unregulated tram crossing.

Visual & Audio Prompt: Top banner animates subtly into view; single distinct chime plays.

Driver Action: Driver adjusts speed and verifies clearance across the tracks.

Crowdsourced Validation: Drivers or passengers can tap a single-touch button ("Clear" or "Hazard Still Present") to maintain real-time accuracy.

1. Expected Business & Safety Impact 35% Reduction in Urban Rail Collisions: Substantial decrease in intersection broadside collisions with light rail vehicles.

0 UI Clutter Guarantee: Streamlined alerts build high user trust and feature engagement.

Municipal Transit Collaboration: Potential for direct data-sharing partnerships with city public transit authorities.
