Citizens weigh travel and parking costs and compare them to other travel options as well as walking to see which option is quick, comfortable, and affordable. Money comes into pathfinding choices in the form of fuel usage and potential parking fees. Comfort is calculated directly to the pathfinding cost with each option adding to the overall cost. When considering only the travel time, a small road can be shorter but its travel speed is lower than the longer highway’s travel speed so the agent chooses the highway in most scenarios if the highway is overall a quicker route.Ĭomfort is an important factor in pathfinding and includes planning the route to be as smooth as possible, avoiding unnecessary turns at intersections as well as finding a suitable parking spot or public transport stop to get off at. While other factors affect pathfinding, time is usually the most important as all agents tend to seek the quickest route to their destination. Time is an important factor when calculating a path. The core of pathfinding calculations is the four aspects: Time, Comfort, Money, and Behavior. Your city layout is only part of the equation when agents decide how to get around Pathfinding Cost They may change lanes to avoid a car accident or a stopped service vehicle or make room for a vehicle responding to an emergency. Furthermore, agents will adjust their route based on events along the way. This cost is calculated using multiple factors such as the city’s road network, traveling time, travel cost, agent preferences, and more which we will cover in more detail below. In Cities: Skylines II agents choose a route based on a pathfinding cost. Agents would take the fastest route to their destination and stick to it, patiently sitting in a traffic jam if one occurred, only changing their route if the road network was modified in ways causing their original path to no longer be viable. Longer response times could in turn mean the fire truck would not make it in time to stop the fire from spreading or save the building from collapse. In the case of a fire, this could mean the fire truck responding would come from the closest station even if it had a longer route because of how the roads connected it to the destination. In Cities: Skylines pathfinding was proximity-based, meaning agents would calculate their destinations or order services by straight line distance without taking the existing road network into account. Pathfinding works in a different way in Cities: Skylines II than its predecessor. Differences between Cities: Skylines and Cities: Skylines II Check out the highlight video below before diving into all the details. In this development diary, we look at how the traffic simulation works and what features the agents (citizens, services, and resources moving around in the city) take into account when making pathfinding decisions. Where do people live, where do they work and what places do they visit in their free time? Where are businesses located and how do they get the goods they sell? Are their customers citizens or other businesses? How do their customers find them and are there other, better shopping options closer by? All of this and more factor into how traffic moves around the city. Managing traffic in a growing city was a core part of Cities: Skylines and going into the sequel we knew we wanted to bring you a more advanced system, both to address the feedback you have shared over the years and to make the city feel more realistic and alive.Ĭitizens and traffic are a core part of a living and breathing city. Hi everyone! We are back with another development diary for Cities: Skylines II and today is all about the new and improved traffic AI.
