Traffic Paths

There are functions in the Path Settings menu that are only available when a pedestrian or vehicle path is selected. These functions allow you more control over how the traffic is flowing through your path.

The Reverse Path button reverses the direction of the path.

The Disable Section button disables the currently selected section.

Pedestrian and Vehicle Paths allow you to automatically populate them with their respective content. Within the dropdown menu is an organized hierarchy of content that can be placed on the associated path. To select content, use the checkbox adjacent to its name.

The Populate button places all of the content that has been selected on the path.

The Speed and Position Randomness sliders allow for a slight difference in speed for vehicles on the path

The Approx. Number to Spawn textbox controls the amount of vehicles that are placed on the path when populate is used.

The Vehicles Respawn After controls the amount of time a vehicle will wait at the end of a section before respawning.

The Spacing textbox defines a padding distance between vehicles.

The Apply button next to Spacing applies the spacing to the path.

The Speed Limit button sets a speed limit to be applied to the path.

The Apply button under Speed Limit sets the speed limit on the selected segment.

The Apply to All button sets the speed limit for the entire path.

Traffic Paths allow you to control the speed of individual segments.

The Segment textbox controls the speed of the selected segment.

The Path textbox controls the speed of the entire path.

The Use Terrain Physics toggles whether the vehicles on the path use the terrain physics.

Disabling the Terrain Physics is a good option if the Terrain that path is placed on is uneven and vehicles on the path have noticeable issues traversing it. If the terrain physics is disabled vehicles will drive along the path segment lines. It is likely that more pins will be needed to smoothly navigate hills.

The Lane Control allows you to make additional lanes with a given path and control the speed of the selected segment, lane and entire system respectively.

Lanes are not always exact copies of the original. An inner corner has a shorter length than an outer as shown in the screenshot below. Left and Right lanes are defined by the direction of the path.

The Multi-Lane Left textbox controls the number of lanes to the left

The Multi-Lane Right textbox controls the number of lanes to the right.

The Custom Lane Width checkbox allows the user to enter a custom lane width. This may cause cars on the path with larger turn radius’s to no longer be able to make their turns

The Lane Width textbox controls the distance between lanes.

The Spacing textbox controls the distance between cars.

The Speed Limits control the speed of the selected segment, path or system. Lanes are considered separate paths from the original unless connected.

The Segment speed limit controls the speed limit for that segment

The Path speed limit controls the speed limit for that path and any other lanes connected to it.

The All Lanes speed limit controls the speed limit just for that segment

There are multiple ways to have the construction schedule interact with different types of tasks. Vehicles, Equipment and Foliage can be added to Construction, Demolition, Temporary and Equipment Tasks. Segments of Vehicle tasks can be added to Traffic Tasks. For more general information about how to create tasks and their functionality see Object Assignment.

Use the Add To Task button to add all the objects on a path to a task.

When Vehicles or Equipment are added to Construction, Demolition and Temporary tasks it can be animated in Fuzor like any other object in the model. For more information see 4D Animations. This means that a stagger animation can be used to place row of barriers.

When Equipment is added to an equipment task an equipment animation can be selected to playback during the task’s duration. Objects can either stay visible after the end of the task or be removed.

Site Egress Paths can be added to Temporary Tasks. If added the associated egress path will be visible during the duration of the task regardless of whether the Site Egress Menu is open. The best way to assign an egress path to a task is to drag the egress path menu into the workspace so that the egress route is visible while 4D is open.

Segments of Vehicles and Pedestrian Paths can be added to Traffic Tasks. This allows the user to control the paths with the simulation schedule. Multiple segments can be added to each task allowing the user to control complex path systems and change traffic routing during the construction schedule.

With the Task and the Path segment selected use the Add to Task button in 4D
