School Bus Hybrid Diesel¤

School Bus Overview¤

The School Bus is engineered to transport 15 or more passengers, serving primarily in the conveyance of students to and from educational institutions.

School Bus Performance Metrics¤

  • Annual Distance (dannual): The school bus covers an annual distance of 24,000 km.
  • Average Occupancy Rate (nlpv): It boasts an average loading capacity accommodating 47 passengers per vehicle.
  • Utilization Window: The vehicle is utilized for 5.26 hours per day, translating to a 22% capacity utilization, according to the study by Duran and Walkowicz1.
  • Reference Capacity: The reference capacity, derived from these parameters, is calculated to be 585.31 passenger-kilometers per hour (pkm/h), utilizing the formula:
\[ ref_{size} = \dfrac{d_{annual} \cdot n_{lpv}}{8760 \cdot c_p} \]

Where cp represents the capacity utilization percentage. Where the denominator reflects the total hours in a year multiplied by the capacity utilization factor.

Hybrid Diesel¤

A hybrid vehicle integrates an internal combustion engine with an electric motor. Unlike plug-in hybrids, this type of vehicle relies on a battery and an electric motor to capture kinetic energy during vehicle operation.

The hybrid vehicle features a lithium battery that is smaller compared to those found in fully electric vehicles, aimed at decreasing fuel consumption. However, the increased weight of hybrid vehicles may lead to higher fuel use.
