I propose the implementation of marking all traffic lights, even those without speed radar, in the Waze app’s mapping system. This feature aims to enhance the navigation experience, provide greater driver safety, and enable more accurate and efficient routes.

Including traffic lights on the Waze map would allow:

1. Greater Accuracy in Route Time Calculation: By accounting for waiting times at traffic lights, Waze’s algorithm could offer more precise route estimates, preventing unexpected delays for users.

2. Suggestion of Faster and Safer Routes: With the location of traffic lights known, Waze could suggest alternative routes, avoiding intersections that require longer waiting times and catering to users’ preference for faster routes.

3. Easier Navigation in Urban and Unfamiliar Areas: Marking traffic lights would aid drivers navigating unfamiliar areas, enhancing safety by providing alerts about controlled intersections and allowing drivers to prepare for stops.

4. Fuel Consumption Optimization and Emissions Reduction: This feature would enable users to opt for routes with fewer traffic lights, reducing the number of stops and starts, positively impacting fuel consumption and emissions reduction.

5. Reduction of Accidents and Traffic Violations: Notifications of approaching traffic lights help prevent red-light running and increase driver alertness in intersection areas, contributing to road safety.

6. Average Waiting Time Indication at Traffic Lights
   
   Description: Beyond marking the location of traffic lights, Waze could display the average waiting time at each traffic light based on historical and real-time data, alerting drivers to intersections that cause significant delays.
   
   Benefits: This feature allows drivers to anticipate waiting times, adjusting their route or speed according to the wait time, thus improving trip planning.

7. Alerts for Traffic Light Timing Changes Based on Time of Day
   
   Description: Many traffic lights adjust the green/red light duration based on the time of day. Waze could integrate these variations and provide alerts for timing changes during specific periods, such as peak hours.
   
   Benefits: Drivers are informed about waiting time changes, which increases the accuracy of arrival estimates and improves route selection during high-traffic times.

8. “Green Wave” Notifications for Synchronized Traffic Lights
   
   Description: In locations where traffic lights are synchronized to form a “green wave” (a sequence of green lights), Waze could indicate this possibility, recommending an ideal speed for drivers to pass through several intersections without stopping.
   
   Benefits: This increases trip fluidity, avoiding unnecessary stops and contributing to more economical and less interrupted driving.

9. Alerts for Traffic Lights with a Record of Accidents
   Description: Some traffic lights are in areas with high accident rates. Waze could highlight these points with caution alerts when approaching traffic lights known for incidents, even suggesting a safe approach speed.
   
   Benefits: This feature enhances road safety by alerting drivers in higher-risk areas and encouraging more cautious driving.

10. Integration of Traffic Light Information with Driving Assistants in Smart Cars
    
    Description: For vehicles equipped with driving assistants, Waze could share information about the location and status of traffic lights, allowing the car to adjust speed and plan stops more precisely.
    
    Benefits: Integration with smart vehicles increases safety and driving efficiency, especially in urban areas with frequent stops.

11. Optimized Route Studies for Traffic Lights at Off-Peak Hours
    
    Description: With traffic light data on the map, Waze could suggest optimized routes during late night or low-traffic times, avoiding intersections with slow traffic lights and proposing more direct paths.
    
    Benefits: Reduces travel time and fuel consumption during low-traffic hours, providing users with a quick and smooth navigation experience.

12. Approach Notifications for Hidden Traffic Lights (Curves, Hills)
    Description: In areas where traffic light visibility is reduced (such as after a sharp curve or on an uphill road), Waze could issue visual and sound alerts in advance, preparing drivers to stop.
    
    Benefits: Increases safety in low-visibility areas, helping drivers avoid sudden braking and risky situations.

13. Indication of Priority Lanes at Controlled Intersections
    Description: At intersections where there are specific priority lanes (such as left-turn lanes or bus-only lanes), Waze could display these indications, helping drivers position themselves correctly in advance.
    
    Benefits: Improves traffic flow by avoiding last-minute lane changes and helps drivers follow road markings correctly, reducing the risk of violations.

Map updates can be carried out through collaborative information from Waze map editors, as well as government data on traffic light locations. I also suggest the option of customizing alerts, allowing users to choose whether to receive notifications when approaching traffic lights according to their preference.

The implementation of traffic light markings on Waze is an innovative proposal, with the potential to improve the precision, safety, and efficiency of navigation. This feature, by adding a new layer of relevant information for users, could elevate the quality of service and make Waze an even more complete tool for urban mobility.
