In each video, the focus is on how the bike sequence works and whether it is a snappy control short cycle length. Prinses Beatrixlaan an artery provide six travel lanes in total, three lanes on each direction, while A4 off-ramp westbound has three travel lanes and A4 on-ramp has a one travel lane see Figure 1. The reason has talked before that what we look at is the red time not the green time. This chapter presents three simulation videos corresponding to each scenario.

Prinses Beatrixlaan an artery provide six travel lanes in total, three lanes on each direction, while A4 off-ramp westbound has three travel lanes and A4 on-ramp has a one travel lane see Figure 1.

Table 1 shows the result of the analysis: Aside of the cycle track, an exclusive bike phase is required to improve the journey time of a cyclists in the country.
In other words, the smaller cycle length, the better.
As shown in Figure 4, another advantage is that the bike path is swing away from the street not directly where on-ramp crossing with Prinses Beatrixlaan, so it shorten the crossing distance for cyclists. The figure above shows the splits for all phases and the phase sequence for three scenarios. Bike first scenario has longest bike delay, This report is to simulate and analysis such a full-actuated signalized intersection at Princes Beatrixlaan A4 highway ramp in Rijswijk, Netherland and provide two phase reservice plan for bike signal.
Apparently, bike-reservice have an advantage over other two bike phase sequences. The reason has talked before that what we look at viissim the red time not the green time. Different from urban intersections, cissim the cyclists involves with traffic at the rural highway, they have a far more safety concern than they are in the urban streets. There will be a fix-time cycle length if it is coordinated control.

So the red time period is either phase 4 or phase 7. Otherwise, The RT vkssim delay increased a lot for both scenarios, which is from Vehicle extension time is 2.
However, the main issue is in Netherlands, cyclists require more protection on the highway interchanges where there is a cycle track crossed.
The intersection is on street level, in this case it assumes that it is isolated control. In this project, cyclist would have to wait two consecutive phases in bike first scenario. Bike phase starts with phase 5 and has a split of 12 seconds. Considering this is a two-direction cycle track and there are a lot of mopeds running on the cycle track, cyclists are provided a protected phase for both directions.
PTV Vissim FAQs
In order to figure out what kind of bike phase sequence is more intelligent, there are three different alternatives to be simulated at the lower ring. Stop line detector is used to make a call to corresponding phase and upstream detector is used to safely terminate the ivssim.
They run in turn and Phase 2 ends up with phase 5. In US and some European cities, the common bike infrastructure is bike lane: For vehicle phases, the minimum green time has been set to 7 seconds, yellow time is 3 seconds and all-red clearance time is 1 seconds. After phase 7 gaps out or max out, bike phase start again, when bike phase ends, NBL turns green.
Due to a large amount of cyclists demand, some European countries like Ivssim, Germany, have developed and provided more dedicated bike infrastructures: Bike minimum green is based on pedestrian crossing time. Modify them so that the sum of splits equals to cycle length, which is seconds.
Cycle track is always physically separated by buffers, medians, bollards provide a more comfortable area for cyclists. Because the intersection is fully-actuated control, In order to let the cycle length should be as short as possible, the through movement critical gaps decreased to 2 seconds.
In this case, even phase 7 max out, bikes gissim have plenty slack time. For bike reservice scenario, sometimes WBL should gaps out but due to phase 7 max out and bike phase has 12 seconds minimum green, WBL still have to wait phase 6 and end up together.
In addition to primary overhead signals, pole-mounted secondary signal heads are also placed on each approach so that drivers have good visibilitty and enough time to determine whether stop or not.
It also overlaps with WBR.
