A Study on the Influences of Exclusive Stopping Space on Saturation Flow (Case Study: Bandar Lampung)

Effect of Traffic Lights Countdown Timer and Motorcycle Lanes as an Approach to the Red Box for Motorcycles in Bali Island

“…The results of previous research in Indonesia show that the application of ASLs for motorcycles is effective in reducing traffic conflict and increasing traffic flow at signalized intersections [16,17]. Another study shows that the implementation of ASLs is not effective because it leaves empty space behind the stop line due to motorcycles not being able to enter the red box area because they are blocked by four-wheeled vehicles [18]. Meanwhile, the results of ASLs research for motorcycles in Malaysia show that intersections with ASLs show a lower rate of traffic conflict compared with intersections without ASLs [19].…”

“…The results of red box implementation showed that the level of traffic conflict had decreased and traffic flow had increased at the signalized intersection [16,17]. On the contrary, other studies stated that the red box is less effective, or there is a lot of free space in the back stop line that should be occupied only by motorcycles and at the same time cannot be entered by vehicles other than motorcycles [18]. Furthermore, the application of red boxes is growing very rapidly in Indonesia.…”

“…Furthermore, another previous study stated that there is a close relationship between saturation flow and occupancy rate of ASLs for motorcycles. A low occupancy rate causes a lower saturation rate than without ASLS [18]. Mixed traffic flow at a signalized intersection dominated by motorcycles is very common in most Asian countries such as Indonesia, Malaysia, Thailand, Vietnam, and Taiwan.…”

The Main Structure of the Prestress Bridge: Ultimate Calculation Analysis Using Bridge Management System (BMS 1992) Planning Method

“…"A signalized turn lane may be installed for any of the following reasons: new traffic signals are being installed, there is a history of crashes between turning vehicles and oncoming through traffic, there are two or more lanes that turn across traffic, turning traffic is opposed by two or more through lanes of traffic, two or more opposing through traffic lanes have high operating speeds, and sight distance to the intersection is limited." 27 The traffic load for the design consists of the load due to lanes, the load due to trucks placed across the road, bridge vehicles which have an effect on the equivalent value in the actual series which depends on the width of the bridge vehicle road. The weight of a single load vehicle on a truck with three axles at any position in the design traffic lane, each axle consisting of two loading contact areas to represent the effect of the wheels of the heavy vehicle.…”
