In the land transportation system, the availability of proper and adequate infrastructure greatly affects the smoothness of traffic. The existence of small businesses along the road is a side obstacle factor that reduces road performance. This happened along the Jalan Alternatif Inspeksi Banjir Kanal Timur, there were many traders on the roadside, pedestrians, vehicles going in and out, slowing down vehicles, and parking vehicles.
