Khartoum, the capital city of Sudan, is characterized by its unique geography, with the Blue Nile and White Nile converging at the city’s heart. The city’s growing population, limited road infrastructure, and the physical barrier posed by the rivers demand a diverse and efficient urban transit system. Three primary modes of transport that could help meet Khartoum’s urban mobility needs are Trams, Buses (including Bus Rapid Transit, or BRT), and River Taxis. Each mode has its own set of advantages and challenges depending on passenger comfort, satisfaction, and return on investment (ROI).

1. Trams – A Sustainable Urban Solution

Description:

Trams are a well-established form of mass transit in many cities around the world, offering a relatively efficient and environmentally friendly mode of transport. In Khartoum, tram systems could operate on dedicated tracks running through major urban corridors. Due to the river’s natural division of the city, tram lines could connect key urban zones across bridges or tunnels, providing a seamless travel experience for commuters.

ROI and Passenger Comfort:

• Return on Investment (ROI):
  The initial capital investment for building tram systems is typically high due to infrastructure requirements (tracks, stations, trams), but once in place, they offer high capacity and relatively low operating costs. ROI depends on factors like fare collection systems, operating efficiency, and the ability to attract ridership. In a dense city like Khartoum, the long-term ROI could be high if the system runs efficiently.
  • Expected ROI Range: 6-12 years before profitability.
• Passenger Comfort:
  Trams are generally designed for comfort, with air conditioning, wider seats, and accessibility features. Since Khartoum experiences high temperatures, air-conditioned trams would likely increase satisfaction, making them an attractive option for commuters.
  • Comfort Rating (Scale 1-5): 4/5 – due to air conditioning, spaciousness, and smooth travel.
• Satisfaction:
  Passenger satisfaction is likely to be high, especially in terms of reliability and regular service. However, concerns might arise regarding delays due to infrastructure issues, especially during peak hours.
  • Satisfaction Rating: 4/5.

2. Buses (Bus Rapid Transit) – Flexibility in Congested Areas

Description:

Buses, particularly Bus Rapid Transit (BRT) systems, offer a more flexible and cost-effective urban transit solution. BRT corridors are often constructed in existing streets or roads, with dedicated lanes to minimize congestion. Buses can operate across the city, providing widespread coverage, including across both sides of the rivers. BRT systems would be a viable solution for bridging Khartoum’s urban gaps and overcoming traffic issues in crowded areas.

ROI and Passenger Comfort:

• Return on Investment (ROI):
  Buses and BRT systems have lower upfront costs compared to trams, especially since they can use existing road infrastructure. A well-managed BRT system, with dedicated lanes and efficient scheduling, offers a good ROI due to the low operating costs. Additionally, buses can serve a broad demographic, from low-income to high-income passengers, making them highly adaptable.
  • Expected ROI Range: 4-6 years with a growing ridership base.
• Passenger Comfort:
  While buses are generally less comfortable than trams, a BRT system can improve this by offering features like air-conditioning, Wi-Fi, and spacious interiors. However, comfort is often compromised during peak hours, with crowded buses and longer waiting times.
  • Comfort Rating: 3/5 – comfortable when not overcrowded, but can be uncomfortable in peak hours.
• Satisfaction:
  Satisfaction can be quite variable depending on wait times and bus overcrowding. However, a well-implemented BRT system with modern buses and reliable schedules can lead to good overall satisfaction. The flexible nature of buses makes them a popular choice for commuters who need access to various areas of the city.
  • Satisfaction Rating: 3.5/5.

3. River Taxis – Overcoming the Nile’s Physical Barrier

Description:

Given Khartoum’s geography, river taxis could be an innovative solution for overcoming the physical barrier posed by the Blue and White Niles. Small, fast boats could operate as water taxis, providing quick transport across the rivers, with docking stations near major urban hubs on either side. They could serve as an alternative or complementary mode to trams or buses, particularly for people living near the rivers.

ROI and Passenger Comfort:

• Return on Investment (ROI):
  While river taxis are less capital-intensive compared to trams, they do require maintenance costs for the boats, docking facilities, and infrastructure. However, given the natural geography, this could be a highly profitable venture. A river taxi system could generate high returns in the long term if integrated effectively with other modes of transport.
  • Expected ROI Range: 5-7 years, assuming effective integration with other transit modes.
• Passenger Comfort:
  River taxis could offer a unique and comfortable experience, with scenic views and relatively smooth travel. However, they could be less comfortable during extreme weather conditions (e.g., rain or heat). They would also need to adhere to safety standards to ensure passenger comfort and security.
  • Comfort Rating: 3.5/5 – scenic and unique, but weather-dependent and subject to river conditions.
• Satisfaction:
  River taxis can provide a high level of satisfaction due to their novelty and the scenic value they offer. However, issues such as wait times, boat availability, and weather-related disruptions could negatively affect passenger satisfaction.
  • Satisfaction Rating: 4/5, primarily due to the unique experience, but with some limitations.
