The Black Arcs Inc. is a civic technology company with their main focus on the visualization of real urban areas in a "video-game" format. They provide a tool called CitiSketch that visualizes whole communities in order to address civic issues. This technology simulates "scenarios" on urban planning decisions and presents the impacts in real-time. For example, the location of a school in a specific region can produce different traffic patterns. With this simulation model, it becomes possible to address and visualize the impacts on the every day life of the citizens and also, decide the location that will have the most positive impact to the community. To achieve this, the software models individual people in the city as independent agents that perform duties/activities as a person would in real-life. The software currently shows different planning strategies for towns with populations up to 10,000 people. For larger populations, the tool suffers from performance degradation due to the large number of agents that are acting independently and the subsequent computing workload it requires. The simulation requires life-like agents to model people; therefore population size reflects the number of agents, which reflects the computing demand and limits the city size. Overall, the software has scaling issues that need to be addressed and resolved in order to make it applicable for urban areas of any population size.

黑弧公司是一家公民技术公司，他们的主要重点是在“视频游戏”格式的真实的城市地区的可视化。他们提供了一个名为CitiSketch的工具，可以将整个社区可视化，以解决公民问题。该技术模拟城市规划决策的“场景”，并实时呈现其影响。例如，学校在特定区域的位置可以产生不同的交通模式。通过这个模拟模型，可以解决和可视化对市民日常生活的影响，并决定对社区产生最积极影响的位置。为了实现这一目标，该软件将城市中的个人建模为独立的代理人，他们像现实生活中的人一样履行职责/活动。该软件目前显示了人口高达10，000人的城镇的不同规划策略。对于更大的群体，由于大量的代理独立行事，以及随后的计算工作量，该工具遭受性能下降。模拟需要逼真的代理人来模拟人，因此人口规模反映了代理人的数量，这反映了计算需求并限制了城市规模。总的来说，该软件存在需要解决的扩展问题，以便使其适用于任何人口规模的城市地区。
