This is a very interesting section of your book about the Metro Express in Mauritius! It covers a lot of ground, and here are some key points I found:

• You're concerned about safety at ground-level stations, especially with people walking on the tracks and potential accidents with incoming trains. You propose using facial recognition cameras and alarms to deter this.
• You raised the importance of short stopping times to avoid delays and overcrowding on platforms, but you're also concerned that this will make it difficult for some passengers, like the elderly, to get on and off the trains.
• You believe that facial recognition cameras are necessary at road junctions to prevent accidents with vehicles and pedestrians who ignore traffic signals.
• You advocate for installing safety features inside the cabins, such as a lock on the door to prevent unauthorized access, an intercom for emergencies, and an alarm system.
• You recommend that the Metro should run overhead on certain roads, such as at Caudan and Quatre Bornes, to avoid traffic congestion. You argue that any aesthetic drawbacks of an overhead metro are outweighed by the traffic problems caused by a ground-level metro.
• You express some skepticism about the overall effectiveness of the Metro in reducing traffic congestion. You mention that feeder buses and extra travel time to stations could negate some of the benefits.

Overall, it seems like you're very interested in making the Metro Express a safe and efficient system.

Do you have any information about the specific plans for where the Metro will run underground and where it will be above ground?

Soman Ragavan :

Thank you. Now make overall comments on the book, list main issues I raise, speak about foresight, security-consciousness, etc. At some London underground stations, there are permanent screens on platforms whereby doors at specific places (opposite doors in the trains) open when the train has stopped. Thus, passengers must move directly from the platforms into the train, without getting access to edges between platforms and the rails.

Soman Ragavan :

While it is agreed that the Metro should have priority all the time, the fact remains that accident risks do exist at rail/road junctions. While car drivers get the green light for going forward across the rail tracks, breakdowns/traffic jams can occur ahead in the road. Thus, some cars might get stuck on the rails, without the drivers being responsible for this. Braking on the trams is slow and often the tram will NOT be able to stop in time to avoid hitting against a car that is stuck on the rails. The driver is helpless : he is hedged in by cars at the front and at the back. This being so, there should be an embedded obstruction detection system on the ground at rail/road junctions to warn tram captains automatically well in advance of blocking ahead at the junction. With a longer warning time, the train captain will have more chance of stopping safely in time.

(20)

Google Gemini :

Analysis of the Additional Recommendation

Key Point: The recommendation suggests implementing an embedded obstruction detection system on rail-road junctions to provide tram captains with advanced warnings of potential hazards ahead.

Rationale:

• Accident prevention: The system aims to reduce the risk of accidents by giving tram captains more time to react and slow down or stop if necessary.
• Driver helplessness: In cases of traffic jams or breakdowns on junctions, drivers may be unable to avoid obstructing the tracks, even if they are following traffic signals.
• Improved safety: By detecting obstructions early, the system can help prevent collisions and minimize potential damage to both trams and vehicles.

Implementation Considerations:

• Sensor technology: The system would require advanced sensors capable of detecting vehicles and other obstructions on the tracks.
• Integration with existing systems: The detection system should be integrated with the tram's control system to provide real-time alerts and warnings to the captain.
• Reliability and accuracy: The system must be highly reliable and accurate to ensure timely and effective warnings.

Overall, the recommendation for an embedded obstruction detection system is a valuable addition to the existing safety measures for the Metro Express. It addresses a potential blind spot in the current system and could significantly enhance the safety of both tram passengers and road users.
