The post-ANOVA analysis suggests that motorcyclists experience much higher exposures than other commuters travelling on the road (Test 1 of Table 3). The runner was found to have a significantly lower mean exposure than for the bus and car commuter for the route along which there was a dedicated pedestrian/cycleway (Test 2 of Table 3) but not significantly different for the route where the runner simply chose a less congested route (Test 9 of Table 3). This suggests that pedestrian/cycleways are effective in reducing exposures for runners. Also, the less congested route for the runner was only an option.
