Thank you. Take a look at this link about 城管 (Chengguan): https://en.wikipedia.org/wiki/Urban_Administrative_and_Law_Enforcement_Bureau

I think it sounds natural enough, however, my question is what do you mean by occupying roads? As in the people are living/standing or staying there without a car OR cars that are taking up space and refusing to move with traffic? Otherwise I may be slightly different answer.
