2.3.2. Test Environment Selection

The buses were tested on the same route, under the same working conditions, at the same outdoor temperature (adjacent dates), and for days having equivalent humidity, that is, all the tests were conducted during either sunny or rainy days, but not both.

Four representative routes were selected of varying congestion levels, from open and clear to congested, to reflect conditions experienced in normal daily operation. The routes are shown in Figure 5 and the respective details are summarized in Table 2.
