This collection contains asymmetrical roads.

These type of roads are a necessity when it comes to creating the perfect flow at intersections. Giving traffic the ability to have dedicated lanes for different directions. Improving traffic flow significantly.

Why are dedicated lanes good?
Imagine a four-way interesection made with the regular 'Two-lane Two-way Roads' (the most basic road there is). All the cars waiting for a green light at this intersection now all have to wait in one and the same lane. However, they do not all want to go to the same direction. Some want to go left, others straight through, and some want to go right. This setup now has three disadvantages:

1) When the light turns green, only one car passes the traffic lights at once. Thus resulting in fewer cars passing the light per cycle.
2) Vehicles (especially trucks) take up a lot of space. Having all vehicles wait in one lane creates long lines of traffic.
3) When you use TM:PE's 'Timed Traffic Lights' you cannot program them as efficient as you would with multiple lanes.

Now imagine you upgrade the 'Two-lane Two-way Roads' into asymmetrical 3+1 roads, with the three-lane side heading into the intersection, and one going from it. Now each direction has three lanes, resulting in:

1) The lines of waiting vehicles for a green light is now 3X smaller (or at least it can be if the direction traffic wants to go is perfectly divided across all three directions off course :)!
2) The amount of vehicles passing the traffic lights per cycle is now 3X or even 3,3X more!
3) Normally a 'Timed Traffic Light for an intersection like this has four steps per cycle (one step for each direction). But because of the dedicated lanes you can now give right-turning traffic an additional green light per cycle!

Play around with these roads at intersections, as well as the Timed Traffic Lights from TM:PE, and see how it improves your traffic flow! Practice makes perfect.

Note: I've added all asymmetrical roads based on Vanilla road textures into this collection, but from different creators. You'll find some variations of these roads from Delta 5-1 and Cylis are the same. The NExt2 replacements from Cylis however have rendered tunnels, while the versions from Delta 5-1 do not. You won't experience any issues when you subscribe to both versions, however subscribing to both does require additional memory. So I suggest you pick one version and leave the other. Which one you choose is up to you.
