The streets of ancient Rome were very crowded, and traffic was often slow. This was due to the narrow streets, the large number of pedestrians, and the lack of traffic regulations. In order to alleviate traffic congestion, the Roman government built a number of roads and bridges. They also established a system of traffic regulations, which included規定禁止在白天使用某些街道, and giving priority to pedestrians.
Despite these measures, traffic congestion remained a problem in ancient Rome. However, the city's traffic system was relatively advanced for its time, and it helped to keep the city functioning smoothly.
