### Measurement Results for E1 Route
Conversely, in the

Figure 10: (**a**) Change in bands and (**b**) box plot display during band-selective measurements on the E1 route. Similarly, the average B in the rear section increased from 0.8649 \(\upmu\)T to 1.1584 \(\upmu\)T in the evening hours. The significant increase in magnetic field values in the center region of the electric bus is attributed to the presence of battery blocks in this region. Additionally, due to the higher traffic density, the increased magnetic field values during the evening hours can be attributed to the increased bus activity, including braking, stopping, and starting. Overall, considering all the measurement results, the recorded magnetic field values are well below the ICNIRP limits (500 \(\upmu\)T and 100 \(\upmu\)T). The box plot illustrating the total RF-EMF measurements conducted for the E1 route is presented in Figure 13. In Figure 13, the red line indicates the median value, while the green diamond and the blue circle indicate the average and the outlier value, respectively. As depicted in the figure, the average RF-EMF values hover around 0.5 V/m. The highest average RF-EMF value of 0.5952 V/m was observed at the driver's position during the evening period. In contrast, the lowest value of 0.3418 V/m was recorded in the middle of the bus during the same timeframe. It can be inferred that these measured values (0.3418V/m and 0.5952 V/m) remain well below the limit values provided by ICNIRP, verifying compliance with current EMF legislation, which constitutes 1.2-2.1% of the lowest reference levels (28 V/m) according to ICNIRP guidelines for the corresponding frequency band (80 MHz to 6 GHz). For the band-selective RF-EMF measurements, our evaluations depicting the contribution of each band to the total RF-EMF are presented in Figure 9.0 It is evident from the figure that bands 6, 7, 10, 12, 15, and 19 (base station downlink bands) contribute the most to the total RF-EMF. In the case of L2_m, there was a noticeable increase in the contribution of band number 8 (LTE 800, UL) in the measurement, with this band contributing 34.7% to

the total RF-EMF. The total contribution from the downlink bands is 43.3%, while the uplink bands (5, 8, 9, 11, and 14) account for 51.3%. Unlike the other five band-selective measurements, it can be observed that in the L2_m measurement, the bands with the highest total RF-EMF contribution originate primarily from the uplink bands of the base station.
