Traffic Intersection Tool

The intersection tool allows to create a stop/restart point on a traffic path, one in each direction . For example, to imitate a traffic light behaviour.

Setting	Description
Intersection	This function is used in a traffic junction, where two or more roads are intersect each other.
Start Time	Start time is basically a The deceleration delay. It is the time loss that the vehicle takes in slowing down to reach to a stoppage, in case the signal is red or to a speed, in case there is a queue which is moving when the signal is green.
End Time	End Time is The stopped delay. It is the time measurement that the vehicle spends at the intersection while it is standing in a queue waiting for the signal to turn green.
Repeat After	The entire function will automatically repeat after this time span.
Start Delay	Start Delay at signalized intersection is computed as the difference in the departure time and the arrival time of a vehicle. It can also be said equal to the total extra time spent by a vehicle at the intersection than what is required if the vehicle were allowed to pass the intersection without any hindrance.

Two different type of use of Intersection Tool

Setting	Description
To simulate a traffic light or pedestrian crossing (force all the vehicles on a given lane to stop for a specified time period)	Select the path and then click on the "Define intersection position" button. Once toggled it allows to define one stop point (or two points for a two-way traffic) which will be displayed as a Blue Dot on the path. Once placed these stop points can be moved in the same way as animation KeyPoints. You can also specify start/end/repeat times. For example, setting these values to 5s/10s/20s will trigger vehicles to stop for 5s at t=5s, t=25s, t=45s etc. "Repeat" parameter is optional, 0-value means that vehicles will stop only once. "Delay" parameter is not applicable in this configuration. Once all is set, press on "Create traffic" button and the changes will be applied. To remove the stop point, press [ ]"Delete intersection" button and then [ ] "Create traffic" button to apply the changes.
To imitate an intersection	Create two crossing animation paths, place stop points on both paths right before the intersecting area and set alternating start/end times and equal restart times. For example, it can be start=0, stop=5, repeat=10 on one path and start=5, stop=10, repeat=10 on the other. On wide roads an additional start delay should be set via the "Delay" parameter: it allows vehicles that are already crossing the intersection to exit the intersection area before vehicles in other direction restart (similar to a traffic light delay on a real intersection).

To imitate an intersection

Create two crossing animation paths, place stop points on both paths right before the intersecting area and set alternating start/end times and equal restart times. For example, it can be start=0, stop=5, repeat=10 on one path and start=5, stop=10, repeat=10 on the other.
