MEL has developed a master plan for transport infrastructure that includes the creation of new major public transit links, including the Lille-Villeneuve-d’Ascq BRT line. This will extend over 18 km and will serve 37 stations across eight municipalities. A frequency of less than ten minutes and 80% traffic on a dedicated site are among the ambitious objectives of this project.

As lead contractor of a consortium, Ingerop is carrying out the design and construction supervision for this line, which will complement the existing network to support urban development and land planning.

This project is part of a sustainable mobility approach: it will encourage active modes of transport (walking and cycling) by integrating them into the design and provide a credible alternative to individual car use. The project has strong environmental ambitions, including a goal of HQE sustainable infrastructure certification.

Description

The Joint Union for Dedicated Lane Public Transport in Martinique and the Martinique Region have decided to implement a public transport system throughout the urban area of Fort-de-France.

Long of 13.9 km, the BRT line will include 18 stations, 2 hubs with park and ride facilities, and a maintenance workshop. At commissioning, the rolling stock fleet will consist of fourteen, 24 m long bi-articulated hybrid vehicles.

Assignment

• Diagnosis and audit of the project
• Assisting in cost control, budget monitoring, funding issues, including the Grand European Project
• Assisting in financial engineering and legal advising
• Assisting in deadline management
• Proposing the legal and financial set-up for the studies, work and operation contacts.
• Assisting in communication activities
• Advising on the selection of rolling stock, intermodal hubs and operating principles
• Technical assistance during design and construction phases up to the BRT commissioning: supervision of contractors, engineers and service providers, follow-up reports, technical expertise
• Assistance during the award of a Public-Private Partnership contract for the design, construction and maintenance: drafting the contract, tendering procedure, negotiation, preferred bidder award.
• PPP contract management up to commissioning

The BRT is inserted in an area where several public transport networks coexist without a common organizing authority (urban buses, intercity buses and taxis). Issues of urban integration and intermodal hubs are mostly complex.

Nairobi Metropolis (capital of Kenya, 4 million inhabitants, 8 predicted in 2045) experiences a rapid growth while suffering from heavy traffic jams and from a low-structured public transport supply.

To solve these issues, a BRT (Bus Rapid Transit) Network has been planned since 2014 by the Government of the Republic of Kenya.

The study focused on the lines 3 (27km) and 4 west (7km).

It included, during the first phase (2015-2016) an opportunity & feasibility study and during the second phase (2016-2019) a detailed design for a high-priority route of 12.5km: BRT Core Line 3.

Characteristics:

• High-capacity BRT concept (16 000 pphpd): operation with high frequency (1bus/45 seconds) and multi-docking bays platforms, overtaking lanes, traffic management at intersections with elevated structures at major crossings.
• 2 vehicles standard options considered: high-floor (~90cm) and low-floor (~35cm).

Description of actual services provided by INGEROP staff within the assignment:

The assignment covered the following scope of tasks:

• Ground survey campaigns: topographic surveys, aerial geo-photography, geotechnical surveys, road deflection surveys.
• Traffic surveys: origin/destination surveys from interviews, traffic counting, directional traffic counting at intersections…
• Transport demand forecast (2023, 2035, 2045)
• Urban integration and technical studies: infrastructure, tunnels, bridges, drainage system and strategy
• Stations study with an architectural concept (3 options) and associated equipment (sliding doors, fare collection and control lines, ticketing systems and intelligent transport system equipment for passengers’ information and operation monitoring)
• BRT Operation studies and transport services design (all-stops and express services)
• Dynamic simulation for the BRT operation and pedestrian flows in stations (VISSIM)
• Rolling stock study (vehicles transport capacity and propulsion options)
• Assessment of Investment cost and Operation & Maintenance costs; Economic and Financial evaluation
• Environmental and social impact assessment (ESIA)
• Implementation plan (contracts framework and implementation schedule)

Brief description

As part of the major projects launched by the city of Dakar in recent years to improve public transport, the construction of a BRT line, an express train line and the restructuring of the public transport network are planned.

In this context, CETUD (the organising authority under the Ministry of Transport) has delegated to Ageroute (Senegal’s road management agency) the project management for the complete construction of this BRT line, which will be used by 250,000 passengers per day by 2050.

Characteristics of the project:

• 18 km long
• 23 closed stations (high platforms ~95cm)
• 1 depot workshop
• 3 interchange hubs (terminus + central station)
• 2 Works of Art
• Passenger information system + ticketing + centralized technical management (centralized command post at the depot)
• Facade to facade” layouts: bus lanes, accompanying roads, pavements, cycle paths, etc.

Assignment

Complete works supervision assignment (construction supervision – Design check – Assistance for acceptance operations)

Ingerop ensures the operational management of the assignment (on-site head of mission) and the management of the main markets through the on-site presence of experts in infrastructure, systems (Passenger information system, Ticketing, CTM), and building.
