The BYD Electric Bus Fleet and the Paris Metro serve different transportation needs and operate in distinct environments. BYD focuses on electric bus technology and global deployment, while the Paris Metro provides a high-frequency underground rail service within Paris. The choice depends on the specific transportation requirements and geographical context.
| Attribute | BYD Electric Bus Fleet | Paris Metro |
|---|---|---|
| Fleet Size | Over 70,000 pure-electric buses delivered worldwide | Over 400 trains are running. The public transport fleet consists of 3,680 vehicles, with the metro comprising 25.49% of the fleet. |
| Operational Range | K series: 250 km (160 miles) under urban conditions; 12-meter low-floor eBuses: up to 450 km; 15-meter low-entry eBuses: 400 km; B13.b intercity bus: up to 700 km (435 miles); 40-ft Battery-Electric Bus: 255 miles. | Covers a 10x10km area of central Paris. The system spans 245.6 kilometers (152.6 miles), primarily underground. |
| Charging Infrastructure Availability | Compatible with various charging solutions; B13.b: DC fast charging (192 kW single-side or dual-side), pantograph charging (up to 500 kW); Partnership with AMPLY Power for fleet operators. | Not applicable, as it primarily uses electricity from the grid, not battery-electric buses. |
| Passenger Capacity | Mexico City: 130 passengers; K12A: 250 people; B13.b: 49 seats, up to 78 total; 40-ft bus: up to 41 passengers plus driver. | Line 15: 1,000 passengers per train car; Line 14: 950 passengers per train car; Lines 16 and 17: 500 passengers per train car; Line 18: 350 passengers per train car; Line 14 (MP14 trains): Can hold 932 people on 8 cars |
| Accessibility Features | Low-floor designs; Barrier-free facilities; HSM 3-point lap-shoulder belts, integrated child seats, portable restraints; Lower deck wheelchair access; Wheelchair areas with safety harness devices, optional electrically operated ramp. | Line 14 is fully accessible with elevators and minimal gaps. Newer lines (15, 16, 17, and 18) are designed to be fully accessible. Extensions to lines 4, 11, and 14 will increase the number of accessible stations. Many stations lack elevators and have significant stairways. Alternative routes via bus, RER, or tram are available for lines that are not wheelchair accessible. |
| Emissions Standards Compliance | Zero-emission vehicles; Committed to reducing carbon footprint and air pollution; Net-zero carbon emissions across entire value chain by 2050. | Primarily electric, resulting in zero emissions during operation. The Grand Paris Express project aims to further reduce emissions through the use of low-carbon materials and energy-efficient designs. |
| Noise Levels | Low noise levels. | Line 13 is particularly noisy, reaching levels of 102 decibels in some sections. Noise pollution can be a significant issue during commutes. Bruitparif monitors and maps noise pollution levels in Paris. |
| Maintenance Costs | Lower maintenance costs compared to diesel or CNG buses; Los Angeles Department of Transportation's electric buses had operating costs about one-third of the compressed natural gas buses. | Not available |
| Route Coverage | Deployed in various cities worldwide; Mexico City's Line 4 is 35 kilometers long with 40 stations. | 16 lines, with over 300 stations. Lines are numbered 1 to 14, with two additional lines, 3bis and 7bis. |
| Service Frequency | Not available | During daytime hours, trains arrive every 2-4 minutes. During rush hour, many lines have trains every 2 minutes. Late at night, the frequency can decrease to every 8-10 minutes or longer. |
| System Reliability | Proven effectiveness, reliability, and efficiency; K8M achieved high scores in structural durability, reliability, maintainability, and safety; BYD produces its own powertrain system, battery, motors, and motor control system; TTC (Toronto Transit Commission) reported that the BYD fleet had been grounded due to a persistent battery fault in March 2023. | Generally considered reliable. Operates from approximately 5:30 AM to 1:15 AM on weekdays, with later hours (until 2:15 AM) on Fridays, Saturdays, and nights before holidays. |
| Integration with Other Transit Modes | Not available | Well-integrated with other public transportation options. Interchangeable tickets can be used on the Metro, RER (suburban express trains), buses, and trams. The RER provides connections to airports and other destinations outside central Paris. The bus network complements the Metro service. |
