Comprehensive Analysis of Magnetic Flux Density and RF-EMF Exposure in Electric Buses: A Case Study from Samsun, Turkey.
This case study measured magnetic flux density and RF-EMF on electric buses on two routes in Samsun, Turkey, across different driving conditions and times of day. It reports route- and condition-dependent variability in magnetic fields, with braking associated with higher readings on one route, and lower overall levels on the straighter route. The maximum RF-EMF level reported (6.01 V/m) was below ICNIRP guideline limits, and band-selective analysis attributed most peak contributions to base-station downlink. Charging measurements indicated higher magnetic-field readings near the pantograph.
Key points
- Measurements were conducted on two electric bus routes (E1 and E4) during morning and evening hours under acceleration, cruising, and braking conditions.
- Magnetic field intensity on E1 varied with bus position, road slope, and passenger load, with notable increases during braking.
- E4 showed lower magnetic field intensity and RF-EMF values, which the authors attribute to a straighter route and fewer stops.
- The highest RF-EMF value reported was 6.01 V/m and was stated to be below ICNIRP guideline maximum levels.
- Band-selective RF-EMF measurements most often identified base-station downlink as the largest contributor to peak readings (11/12 measurements).
- Statistical testing (Anderson-Darling) indicated a generalized extreme value distribution fit for both B and RF-EMF measurements.
- During charging, magnetic-field readings were higher near the pantograph compared with other locations.
