Pompeii had a grid pattern of narrower streets, which were suitable for one-way traffic. On this paper, the traffic-controlling is discussed, followed by the reconstruction of carts and some impediments related to the carts such as stepping-stones, public fountains, and parking animals/carts, and town gates. The main cart-traffic artery can be detected, finally, besides the broad streets called Cardo and Decumanus. Carts running in Pompeii: on the narrow streets a 4-wheeled carts were severely to be restricted to a minimum and the use of certain 2-wheeled carts encouraged. In addtion to the 4- or 2- wheeled carts, which should be preceded by a 'runner' (cursor) in Pompeii, pack donkeys and men carrying packs were also possible. The runner on the cart, who controlled the cart using the brake, was also definitely need, because of the slopes quite steeply in that town. Impediments on the streets: the stepping stone and public fountains were physical impediments against the cart traffic. Parked animals and carts, which also partially obstructed the streets, are negative evidence of well-regulated lane traffic. On a distribution maps of tethering holes of parked animals cut into sidewalks (Fig. 14) the designated find occurs in sufficient numbers and they spread for meaningful patterns to emerge as below. 1) All observed streets have holes cut into sidewalks on both sides except for a unique case of the southern part of Via di Porta Nocera. 2) Outside of the gates, there is no example of the holes. This means that animals could be quite popular in the transportation inside of the gates. 3) Some areas that form throughroutes to the Vesuvio, Sarno, and Nocera Gates tended to have a high frequency with which these holes are found, as well as a high occurrence at the wide streets around the Forum. 4) The holes in the north-east area of Pompeii occurred more frequently than in the south-west area. We possibly overestimate the capacity of Strada Stabia for transportation and underestimate that of Strada Consolare without any stepping-stones and public fountains as obstacles against cart traffic (Fig. 9). Gates: the town gates of Pompeii were built to a common design, narrowed to only one lane and providing one-way alternating traffic, except for the Ercolano Gate. That means the carts entering and exiting the town through the gates were stopped, even though the streets leading to the gates were enough to accommodate two lanes of cart traffic moving in opposite directions. An attempt has been made to classify these gates not by shape, but function, such classification do much to aid our understanding of the cart traffic. This comprehensive and orderly classification of their 5 types in Fig. 18: the highest is the Ercolano Gate build on almost flat ground with two-way lanes, two sideways, two passing places on both sides, and holding area on the outside. Main cart-traffic artery: Strada Consolare shows a few of design feature directly related to their function as the main traffic artery, most importantly to provide secure one-way alternating traffic, such as good visibility and waiting places. Cart drivers chose this route connecting to Via della Fortuna and Strada Stabia rather than the Strada Stabia leading to or from the Vesuvio Gate. Pompeian local government keep cart traffic moving not by standardising the construction of vehicles and streets, and not by controlling or regulating the behaviour of drivers either. But it forced cart drivers to follow the route they intended by avoiding snarled, inconvenient, and inefficient traffics.
