SimCity 4: Rush Hour is an expansion pack for SimCity 4. It includes more options than the original SimCity 4, most of which are transportation related. These include Avenues, Car and Passenger Ferrys and more. Rush Hour also provides a tool which traces what sims use what route and where they go, and which kind of transportation they use. In addition, several mods for SimCity 4, including the NAM(Network Addon Mod), will only work with Rush Hour. Rush Hour is also included in the Deluxe eddition of SimCity 4 and the SimCity Box.
One-way Roads- Are the same size as normal roads but they only allow traffic in one direction.
Avenue- Are dual carriage roads with the same size as highways, and bushes and shurbs in the center. The only way pedestrians could cross is when a road/street/one-way crosses the avenue.
Ground Highway- Are much cheaper than elevated highways and have the same capacity. Can also connect to roads in the same way.
Elevated Rail- Cheaper than subways to set up, though more expensive to run, the Elevated Rail connects to your subway network, but has the drawback that it disturbs surface infrastructure during construction (whereas subways can be built under houses, etc.
Toll Booth- Put on roads, streets, avenues, and highways to receive some revenue. They also cause traffic delays and obviously only work when cars pass by.
Monorail- Works the same way as an elevated railway, which can pass over ground level road and rails; but are much faster and modern-looking than elevated railways.
Elevated to Subway- Connects elevated railways to subways and vice versa.
Ferry- Can carry passengers on water. They can be two types, passenger or passenger and cars.
Route Query- Provides information as to where and how sims get to work and get to home.
Difficulty Levels- On the original SimCity 4, it was near impossible to get a sustainable city as running costs, i.e for infrastructure like roads and for civic services, outweigh tax revenue. In Rush Hour, 3 difficulty levels were introduced, with the hardest identical to SimCity 4, and the easier levels having greatly amplified tax income. Toll booths were also introduced to raise money.
U-Drive It- An add-on which allows players to controll cars, airplanes, boats, and other vehicles. Some vehicles contain special features such as the police car which has a siren. There are two modes of driving, Free and Mission mode. In Free mode gets to drive where-ever you want, while during a mission you must complete certain objectives within a certain time limit . A vehicle recives damage if it crashes into other vehicles, or is driven into water/land, and will eventually burst into flames and explode. The color diamond above a vehicle will change from green to red, depending on the current state.
UFO- A new disaster which causes an large UFO ship to appear which flies around fireing lasers. It can also spawning three more 'baby' UFOs which will fire lasers of their own.
AutoSaurus Wrecks is also a new disaster which causes nearby cars to stick together and form a monster which will then proceed to cause damage to your city.
There are also some music tracks added to the game.
