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)
