Fig. 8 Suggested commuting path with least inhalation pollution

By comparing the commuting and non-commuting paths with the least inhalation of air pollution path, it can be concluded
that in addition to air pollution, the duration of travel also has a significant effect on the amount of inhaled pollution. Although
the difference between the length of the commuting and non-commuting paths is only 1.7 km, the inhalation of pollution in the
commuting path is 23.7 μg more. This difference in the amount of inhaled air pollution is because the trip duration and the
amount of cumulative air pollution along the commuting path are greater than the non-commuting path.
Table 5 shows that the use of the proposed routing model reduces the amount of inhaled pollution in the commuting and
non-commuting paths by 31.8088 and 1.7391(μg) respectively.

4. Conclusion
Due to the increasing use of vehicles in urban areas and the resulted problems, the use of bicycles has been considered as a
strategy for the development of transportation in many cities around the world. Despite the benefits of this approach, using a
bicycle can increase air pollution inhalation. The present study seeks to increase bicycle travel by presenting a routing model to
provide the most popular route with the least inhaled pollution. For this purpose, the inhalation of pollution on commuting and
