Maxis Explains SimCity’s Transportation Systems
Maxis takes a look under the hood of SimCity‘s transportation systems in a new blog post on the game’s official website, posted today. The post is worth reading if you are keen on getting an understanding of how vehicle behaviors, intersections and the like work in the game.
Interestingly enough, every type of vehicle in the game—be it a car, a scooter, or a truck—is assigned with a set of performance characteristics such as top speed, acceleration, and deceleration. These values are further altered by the wealth value of the vehicle, as well as packages these vehicles may be carrying.
The blog goes into some depth about the behaviors of emergency vehicles, which function differently from regular ones. In addition to how they usually behave, the game’s most recent update added some new functionality that prioritizes emergency vehicles over other road users. Here’s what that patch did:
The first change was to ensure that these vehicles could exit their garages and get onto the road as quickly as possible and deal with the emergency. This means that they will immediately reserve a spot on the lane outside the garage and drive straight onto it. Previously they would have to wait for a spot to open up which may never have happened during times of congestion. The second change was allowing them to use any lane on the road regardless of whether they were required to turn left/right at the next intersection, which as previously mentioned, would normally force the vehicle to attempt to get into that lane.
