In case you want to build a bridge or a tunnel, just drag the road across the area and if it’s over a body of water or through a steep hill, a bridge or a tunnel will automatically be created.
There are also several types of road tools you can use to create a road grid more easily and quickly. The curve and arc tool, for example, can be used to quickly create perfectly circular roads. The rectangle tool, similarly, can help you lay down entire blocks at one click of the button.
If you are having trouble planning the spacing for the zones in your layout, you can use the white dotted lines. Hover the cursor over a road to make the lines appear. You can figure out the spacing by referencing the lines.
Once you lay down the roads, you might want to upgrade or downgrade them afterwards. You can do this without rebuilding all over again. Upgrades will of course cost you money and downgrades are free. However, you cannot upgrade streets to avenues without demolishing because avenues require more space compared to streets. To upgrade/downgrade, just select a road segment and you will get some options where you can determine its density.
Make sure to plan ahead when building roads, plan your avenues and streets and intersections keeping in mind the traffic and the building around it. For important building with a high traffic such as hospitals and landmarks, it is best to use avenues so you don’t have to deconstruct later on.
In case of traffic jams, the road menu will inform you. Pay attention to how severe the situation is and accommodate the traffic accordingly. If all else fails, remember that you can always turn to mass transit alternatives.
There is much more to road planning than that, however, but experience might be the best teacher in this case. Try to consider every angle, all the residents that need to use the roads. For example, the employees at the residential areas need to get to the industrial area to work. The industrial areas need to dispatch freights to the commercial areas to sell manufactured products.
The utility vehicles also need to make their occasional rounds and then there is the low land value around the utility buildings to consider. Other occurrences can also appear on a short notice like emergencies such as a fire, in which case a crowded street or a clean open road can mean the difference of life and death. There can also be a surplus of tourists especially around certain attractions.
How To Manage Roads
Although road planning and construction is an initiative task in your city, it largely depends upon various other factors for good operation, such as the location of your Residential, Commercial, and Industrial zones, the location of the highway, the ability of your city to attract tourists, and more.
Thus, it’s important to understand how to manage roads carefully. Sure, the High Density Avenue sounds like an attractive offer, but you shouldn’t go jumping towards such large road systems until and unless you know what’s at stake.
For starters, you need to understand that your roads limit the density of the nearby zones. If you have higher density requirements, then consider going for the best solution to road management, which is the Mass Transit system. This system will greatly reduce the amount of cars on the roads by adding public transport services such as buses and streetcars.
If you wish to create a city with only low and medium densities, consider building the Medium and Low density avenues and roads. This will cap the density amount in the zones in vicinity of the roads – an ideal way to control your city’s inflation.
Another important thing to remember is to avoid creating intersections near the Highway. The highway rarely uses public transport, so if you have intersections there, there is a huge chance of major backups. Perhaps the ideal choice for connecting your city to the highway is the Medium Density Avenue.
Your roads are also responsible for the freights that the industry carries to the commercial zones, and also the ones that may come from the Ferry Terminals and airport. It’s important to create a system that avoids conventional traffic to come in contact with these freighters. Try building linear roads that run from industries to commercial areas, and also link your industries to the trade depots in such a manner that normal traffic doesn’t come there.
Garbage and recycling trucks will also be in the process of transporting material from one place to another, thus stopping near ever building. Make sure to avoid building recycling plants in places where the trucks would have to go through the avenues.
Another thing you’ll wish to keep in mind are the Fire and Police stations. Emergency vehicles will automatically take the shortest route in your city, and it’s always important that you zoom in and track them once in a while to understand the efficiency of your roads. If these all-important vehicles get stranded in traffic, then there are massive risks of life and building destruction.
Thus, it’s always a good idea to locate the Fire stations and police stations in the central area of the city, ideally near a high density avenue (if you have one).
Last but not least is tourism. Ideally, your road design should be such that your tourists do not have to use the roads at all! Try placing tourism attractions like casinos and landmarks near train stations and ferry terminals.
Make sure that accommodation modules are also built so that tourists don’t have to travel inside the city to spend their nights. It’s also extremely essential that you have the Bus and Streetcar terminals up and running when you decide to create a tourism infrastructure.
