Just like rail editor, the road editing is one of the key features in EEP. Indeed, all these communication tracks are essential to build a dynamic and realistic layout. In this editor, you have at hand all the tools you need to build the first bricks of your road network. As always, start small and you will expand your network as you go along.

Summary

Note : EEP contains four similar editors for editing rail, road, tram and river tracks. The construction principles remain the same from one editor to another for all these communication tracks.

This article is divided into two main chapters:

  1. The presentation of the editor located in the 2D plan window with its interface and functions. This will allow us to lay roads, adjust them to any height in relation to the surface of the land or even duplicate a road section,
  2. The detailed  construction of a road, its properties, etc.

Presentation of the routes editor

The editor is divided into four sections:

  1. Select a road style
  2. Choose a type of road
  3. Adjust the height of the road
  4. Duplicate the route

All these tools already constitute a solid basis for the construction of roads. Other tools will be added later.

We suggest you run the article normally, at least for users who are new to EEP to fully understand the process.

Road style

Road style (1st section)

This first section groups together in a drop-down list several dozen different road models. By default, this is the Road2 model. Nothing prevents you from opting for another style of road. Here, we have chosen  County road embankment. When you click on the list, it opens for you to choose a road style. It could be for example a national road, a snow-covered road, a damaged urban road, etc.

Not all roads are translated into English, but upon selection, a preview of the model appears in a small window, allowing you to view it in all its forms before laying in the 2D planning window. Clic here to learn more about manipulating objects with the mouse in the preview area.

Once you have decided on the style of road to lay, it is time to move on to the 2nd section to choose the type of road.

Road type

Type of road (2nd section)

In this section, you can see five buttons listed as well as an Electrified Road checkbox to lay utility poles along the road. Of course, here we are not going to run an electric wire over the road! Moreover, if you display it in the 3D window, you will see that no cables are visible. No, this function will just serve as a benchmark to put posts at each end of the sections to bring in public lighting. Remember in the railroad editor, the white dots symbolizing the location of the catenary posts. Here, it will be the poles for public lighting.

Note : Some routes are nonetheless originally designed with an electric cable, especially for electrified buses.

Description of the buttons:

  1. Lay road : This is the basic road,
  2. Place 3-way switch : this is a 2-branch turnout (3 possible directions),
  3. Place 2-way switch : this is a 1-branch turnout (2 possible directions),
  4. Place road end inc barrier : end of road with construction site barrier
  5. Delete road.

Click on button 1 to select lay road. Now click in the 2D planning window to lay your selected road. At first, we recommend that you do this to familiarize yourself with the way things work.

Note: Each time you create a road or a fork, you will notice a small green triangle on the left and a green point on the right. These symbols correspond to the direction of traffic.

In this image, the direction of traffic is from left to right.

Indeed, the green triangle on the left indicates the start of the road and the direction of traffic. The green circle on the right indicates the end of the road . Dark red arrows at the ends indicate locations for making further connections between sections.

In this image, the direction of traffic is from right to left.

Here we easily notice the reverse direction of circulation.

Important : The direction of circulation is essential for the placement of contacts and signals. By default, the signals are placed to the right of the road in the direction traveled by vehicles , but from EEP9 you have the option of moving them to the other side of the road track. We will come back to this when we get to the chapter on signals.

Finally, to delete a road, select it and click on the Delete button (button n ° 5) or press the Delete key on your keyboard.

Road height

Road height (3rd section)

Here are grouped all the properties to manage the heights of the road. This is the absolute and relative height (we’ll get to that later in this article).

The Alignment property has an input box as well as a button for adjusting the height between the road and the landscape surface.

The Alignment property has an input box as well as a button for adjusting the height between the road and the landscape surface.

Before entering the new coordinates, you must select the road in question.

There is a difference between absolute and relative height. The absolute height refers to the height of a model (here in this case the road) compared to the original surface which remains unchanged (generally at level 0). The relative height determines the difference in height between the road and the actual area of ​​the landscape.

The height parameters of the roads influence certain parameters (number of layout nodes for the aspect of slopes, etc.). 

Road duplication

Before EEP16 (as a reminder)

Versions prior to EEP16 had a different panel. For users still working with these versions, here is a quick reminder about duplicating road:

Duplicating the road (4th section)

In this section, you have all the tools you need to duplicate roads and thus quickly build an entire road network.

Start by selecting the road to duplicate. Then you can choose from 5 options for the direction you want to duplicate (left, forward, right, above or below). Regardless of the direction, you can reverse the nominal direction of the road. To do this, first click on the Invert checkbox.

Start by selecting the road to duplicate. Then you can choose from 5 options for the direction you want to duplicate (left, forward, right, above or below). Regardless of the direction, you can reverse the nominal direction of the road. To do this, first click on the Invert checkbox.

You can also adjust the spacing (in meters) of the new duplicated road from the original lane. The default is 4.5 meters.

The Maintain Style check box allows you to retain the style of the original road. If this box is unchecked, you will be able to select another style in the list of the 1st section at the top (with the effect of updating the list at the bottom) and to apply this new style to the duplicated road. Refer to chapter 4.6.4 Duplicating road tracks on page 109 of the EEP15 manual for more information (This chapter also applies to all other types of tracks: tram, road, river …).

From EEP16

Duplicating the road (4th section)

From EEP16, we see that the single section of the previous versions is now split in two and named respectively: Add extension and Duplicate in parallel.

The first section speaks for itself with its two add extensions Backward and Forward buttons. In both cases, the road to be duplicated must be selected.

We will now focus on the second section. Here, a single button is used to duplicate the selected road in parallel according to:

  1. From a lateral distance indicated in the Distance to left entry box. The default lateral distance is set at 4.5m. A distance to the right is obtained by entering a negative number.
  2. By a height distance indicated in the Vertical height input box. The distance for the default height is equal to 0. A downward distance is obtained by specifying a negative number in the entry box.

We also find a checkbox with the option Road relative  taking into account as a basis of calculation, the parameters of the possible tilt of the road selected to determine the height of the new duplicated road, or the height of the latter in relation to at field level. You will find below, two images to visualize, better than a long speech, the result of this functionality (the white line delimits the height of the road compared to the surface of the ground):

Option Road relative deactivated
Option Road relative activated

Another checkbox is at our disposal with the option turn around (formerly invert) to lay the road in the opposite direction.

Inherited from older versions, the Maintain style checkbox has disappeared and this option has been logically replaced by a drop-down list with the default value: Keep road style and which allows you to keep the style of the original road or ‘apply another style instead.

Build a road

As you may have noticed in the (Choosing the type of road), positioning the first section of the road is quick and easy. There are two possibilities to place a second road after the first:

  1. Either you use the duplicate function with the Duplicate forward option,
  2. Or you click again on button 1 to add a new section. Once it has been placed on your layout, all you have to do is approach it to the first one by holding down the left mouse button to automatically make the connection.

Option 1 is faster because the connection is made automatically and preserves the exact extension from the coordinates of the previous section. In the case of a curved road with an angle of 6.4 ° for example, the duplicated road will take over the properties of its neighbor and an angle of 6.4 ° will also be applied. The same goes for height.

But exactly, how do you bend a road? We have two methods at our disposal which we will detail below. In both cases, the road must be selected.

Bend a road (1st method)

Two separate functions, curvature and extension, can be changed via the mouse:

The curvature : As soon as you move the short line (perpendicular to the axis of the road) with the mouse pointer, only the curvature of the section is modified and the initial length is kept.

The curvature : As soon as you move the short line (perpendicular to the axis of the road) with the mouse pointer, only the curvature of the section is modified and the initial length is kept.

The extension : As soon as you move the longest line (with an arrow) of the road with the mouse pointer, only the length of the section is affected and the initial curvature is kept.

The extension : As soon as you move the longest line (with an arrow) of the road with the mouse pointer, only the length of the section is affected and the initial curvature is kept.

In all cases, the road is rotated directly with the mouse when the cursor is on the center of the section, as in the image below:

If you need to be more specific, it’s time to move on to Method 2 below.

Bend a road (2nd method)

Right click on the track to open the context menu and choose the Track Properties command from the 2D window or Object Properties from the 3D window. A window will open as in the image below:

Road properties window

At first glance, that’s a lot of information to understand but don’t panic! You will see that it is not that difficult.

The Start position frame groups together the coordinates of the X, Y, Z axes, the relative height, the value of the angles for the position of the road on the layout.

For example, to change the rotation, enter the desired angle value in the Angle z entry box located in the Start position box. Your road will thus be oriented precisely according to your wishes.

Once all this information has been entered correctly, all you have to do is click on the OK button to validate your settings, close the properties window and see the result in the layout.

The Characteristics framework has evolved considerably since EEP16. Indeed, the structure and management of all transport networks have been completely overhauled. This results in an improvement in the functionality of the editor in many areas, especially for curves. Until now, EEP offered curved road that did not exactly reproduce the precise characteristics of real curved road.

The new roads in the library integrate these different types of parameters, so that a multitude of curves can be created. This makes it possible to reproduce road systems identical to their real counterparts. Features tailored to a particular curve shape allow more precise editing. Typical tasks in these editors are extending a track to a certain starting or ending point or connecting two points when certain conditions apply at the different points. The use of appropriate curved shapes can better solve these geometric problems.

You can watch the chapter Building a traffic network of the EEP manual to discover the basics of these new curves. The most impatient can directly access the full article EEP curves to learn more.

Important : All the parameters of the new forms of curves apply equally to rail, road, tram and river tracks. The construction principles remain unchanged from one editor to another for all these communication tracks.

Tilt (Inclination)

The Tilt (Inclination) frame defines the elevation of the exterior side relative to the interior side of the road. Unlike straight sections, where both sides of the road are at the same level, in a curved section, the outer side is slightly raised above the inner side to counteract centrifugal force. The value of the elevation is expressed in degrees. To reverse the tilt, you can enter negative values.

Tilt properties

More settings

In the More settings frame, we find two options: Electric and One-way traffic.

Electric

Unlike the railway editor, activating this option to try to lay a conductor cable above a road will not be of any use to you. This feature is just there to materialize the location of future street light poles at each end of the sections. White circles marking the appropriate positions for the posts will appear and all you have to do is put them down. Here it is necessary to distinguish on the one hand, the models of roads originally designed with an overhead cable, in which case the cable will appear above the road and on the other hand, the models that are not equipped with an overhead cable. of this feature. In the latter case, even if you activate the Electric function in the road properties window, it will have no effect.

We can ask ourselves the question: “But why an electric cable above a road?” and the answer: “How about a trolley bus with tires and an overhead electricity collection? If your network has roads of this style, the Splines XXXXXXXXXX function will be very useful for you to lay your poles along the track.

One-way traffic

Activate this option to turn a two-way road in to a one-way. Once activated, all vehicles will drive in the center of the road. Of course, if the road has a central broken line, this configuration will not be visually credible. Ideally, select a road without central marking and if necessary reduce the width of the road using the manipulator (Gizmo) in the 3D window. We can see some examples in the images below:

One-way traffic option disabled
One-way traffic option activated. Cars drive in the center
One-way traffic option deactivated and road without marking

Properties of the zigzag course of the Catenary

This is the zigzag setting of the catenary wire. On an electrified route, the catenary wire is not always centered, but is moved laterally in relation to the center of the road, preventing premature wear of the pantographs. You can determine how far the wire is offset from the start and end of the section, easily and precisely by using the start and end of line sliders (values ​​are in centimeters).

Show switch lantern

Here it is necessary to clarify things. For a road, strictly speaking, we can not speak of a switch but rather a fork, junction, motorway ramp, garage exit … and more generally any section of road that connects to other sections.

Even for roads, you can decide whether or not to hear the sound of the needle as it moves. At least, this makes it possible to ensure the smooth running of the operation by an audible alert.

Several options manage the physical location of the direction sign: hidden, right, left or automatic.

Fork settings
Direction sign switched to [Main branch]
Direction sign switched to [Branch]

The other properties and options common to the connection and connection of communicating tracks are already covered in the article Rail Tracks editor starting at the paragraph List of associated contacts and on.

The same goes for the context menus of 2D and 3D windows that we can find in the article Rail Tracks editor in chapter Contextual menu.
