This paragraph addresses the morphological challenges of ploting bthe hybrid planning of penetrating center tocross the Tamezguida mountain massif by looping westward to reach the Ain Romana railway station starting from the station of Houch El Messaoudi at an altitude of 430 meters and reaching Tamezguida at an altitude of 580 meters with a gradients angle not exceeding 3 per thousand.

This section faces morphological and climatic challenges represented by steep slopes in the fragile terrain of Médéa region .The presence of monkeys as well as conditions related to snowfall and fog in the highlands.

To overcome these challenges safely , the optimal elevation is determined at levels that ensure clearance from snow and fog peaks and avoidance of the monkey population.

The planning relies on separation and integration engineering combined with landscaped design adopting an open hybrid line with a limited number of intermittent tunnels whose total length does not exceed foor kilometres , integrates with giant bridges.

The structures ensures the crossing of low terrains and deep valleys with complete fluidity and high safety in a healthy ecological environment.

The railway track is separated from the monkey habitat by looping around the Tamezguida mountain massinf at open levels not exceedings 600 metres,with route protection via specialized systems at tunnel entrances.

The high bridges alow forest animals to pass without fragmenting their natural habitats.

The route shown on the map represents a model for the hybrid line conneting the station of Houch ELMessaoudi station to Ain Romana station by looping around the Tamezguida mountain massif featuring penetrations through short separated tnnels integrated to bridges designed with landscaped engineering in an ecological area away from the rainforest habitat of monkey and geological complexities deep within the mountain range .offering panoramic views towards the urban area of Tamezguida and expensive outlook toward the western landscape.

10. Structural challenges and the design of penetrating center via engineering of separation and integration

The north south railway project in its section of penetrating center faces significant geotechnical and engineering complexities due to its passage through seismically active zone and rugged mountain terrain.

This imposes sever structural challenges regarding the stability of technical structures and the safety of train operating .

To overcome these difficulties and safety mitigate risks the engineering of separation and integration is implemented as a pivotal strategy .

This approach relies on advanced structural joints that allow structures to move and absorb shook without suffering structural collapse .

The blocks of bridges and tunnels are separated technically to prevent the transfer of kinetic stress between structural components while the rail track remains continuous withis a resilient alignement during critical impacts.

The Ain Romana station is equipped with advanced monitoring and control devices , functioning as a sophistical center for sensing and recording vibrations in the technical structures .

This center is integrated with the center of meteorological tower and its associated stations in Ouzera area enabling the comprehensive collection of data derived from climatic and geophysical parameters along the entire alignment.

Data is processed and analyzed within the smart monitoring center enabling the central control to make proactive decisions in coordination with stations along the mountainous railway line.

This facilitates the efficient management of train traffic and the regulation of operational speeds in strict compliance with the standards of safety.

11. Conclusion

The sustainable urban planning for healthy and scientific smart city requires the adoption of integrated strategies that skifilly balance the separation and integration .

The spatial separation based on one health approach services as an essential tool to isolate sensitive facilities and zone of logistics in order to prevent operational risks and maintain a healthy secure environment.

Conversely the separation and data integration represented by ultra digital networks and intelligent systems ensure smooth transportation and seamless exchanges of data for research and innovation.

Balancing separation and integration in the planning of Ouzera City to serve as a model for healthy and scientific smart city integrating advanced scientific research approaches with environmental health requirements.

Furthermore the logistic zone of transportation was planned along the railway line between Chiffa and Berrouaghia using transit oriented planning strategies with a strong emphasis on separating freight and passenger stations and through strategic connection with the north south motorway and exchanges urban axes across El Hamdania Médéa Ouzera Benchicao and Berrouaghia.

The efficiency of logistical operations has been enhanced while safe guarding the urban environment and ensuring the resilience of infrastructure of transportation as a whole.
