“…By changing the road type from 2.2TT to 4 / 2TT, it is necessary to construct one bridge with one side of the existing Liliba bridge, so that each 2-lane bridge can be traversed by traffic in one direction. In the study [23], side friction affected the reduction of road capacity significantly (up to 60.73%) from the road base capacity.…”

Problems when the flow of traffic on urban roads exceeds the road's capacity, resulting in traffic jams. It happened on the Piet A. Tallo street during peak hour conditions. Especially in converted type of route from 4/2T to 2/2TT, which results in a buildup of traffic flow at that point. This research aims to analyze the volume to capacity ratio (v/c) and provide recommendations for long-term strategies to reduce traffic jams on Piet A. Tallo Street. Traffic flow and capacity analysis based on Guidelines for Indonesia Road Capacity 2014 (PKJI2014), while the projected growth in the number of vehicles in the next 20 years, uses the linear regression method. The results show that peak traffic flow exceeds road capacity in the 2/2TT segment with a v/c ratio of 1.08. Recommendations for handling this by regulating side friction and changing road segment type 2/2TT to 4/2T. Using linear regression projected traffic flow in 2040, road capacity can still serve traffic flow with a maximum v/c ratio of only 0.93.

“…As a result of using these two different types of PCU values, a 10-53% capacity reduction was observed in bus bays and bus stops and about 28-63% due to on-street parking. Authors in [1,19,24,32,52] investigated urban arterial roads, finding that parked and stopped vehicles act as frictional elements that majorly impact traffic flow, LOS, speed, and delay. On-street parking has been highlighted as a substantial source of side friction in urban arterial roads, and there is a relationship between the presence of on-street parking and the reduction in stream speed.…”

This study reviews the impact of roadside friction on urban arterial roads in the published literature and aims to identify the various side frictional parameters that impact urban arterial roads. The side frictional parameters are non-motorized vehicles, pedestrian crossing or moving along the road, street vendors, on-street parking, animal movement, and land-use activity. The impact of all these parameters on traffic performance leads to a reduction in capacity, speed (instantaneous speed, journey speed, travel speed, time mean speed, and space mean speed), level of service, delay, travel time, and travel cost. This study considered online published studies from 1995 to 2022. The available effective width and the percentage reduction in road capacity are related. Road capacity is reduced by 3.37% when the effective width is reduced by 2.95%, while road capacity is reduced by 26.08% when the effective width is reduced by 21.81%.

“…and therefore to enhance transport equity in many different metropolitan areas. A different approach is the one presented in the study of Biswas et al (2020) who argued the introduction of Divided Arterials. According to their study, pedestrian movements and crossing and onstreet parking manoeuvres cause capacity drop and consequently they downgrade the efficiency of the transport system.…”
