Display Field: HANDLE

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Basic Description: The polygon feature class Fig. 6.3 Evidence for Right-Side Driving (filename- PBMP_RSDD_City_Poly_001 ) represents the percentage of certainty values from directional evidence that demonstrates driving on the right side of two-way streets at Pompeii as published in figure 6.3 of Poehler, Eric E. 2017. The Traffic Systems of Pompeii (New York: Oxford University Press). Data History: The attribute data for these features were derived from figure 6.3 and table 6.4 of Poehler, E. The Traffic Systems of Pompeii (New York: Oxford University Press) and were produced by in-field observation and documentation by the author between 1998 and 2016. Calculations of the evidence from curbstones and guard stones (stepping-stones were considered separately) were made as follows: “For each street, the number of directional wearing patterns and the certainty of each pattern was associated with a side of the street and then considered against the direction interpreted to determine which side of the street drivers were using. For example, on via di Nola, sixteen total wearing patterns were found, thirteen of which show vehicles moving either westbound along the north curb or eastbound along the south curb. These had a total certainty value of 40, which compares with a certainty value of 5 for the three wearing patterns found to suggest driving on the left-hand side of the road. The difference between these two certainty values is also expressed in table 6.4 as a percentage of the whole, in this case revealing that 88.9% of all the traffic on via di Nola moved along the right curb, while only 11.1% can be shown to have regularly impacted the left curb” (p. 150). After joining the information on surface types to the Streets (STR) layer, the streets were given a three meter buffer to improve visibility of the attribute data. Spatial data in this layer are based on a CAD file provided by the Soprintendenza di Pompei to Eric Poehler in 2003. The CAD file was created by digitizing the RICA Maps of Pompeii, 1984, supported by World Monuments Watch and funded by American Express. The RICA MAPs were drawn in part from aerial images taken at 820m and supplemented by on the ground survey. Inconsistencies among the features of this layer with satellite imagery or other maps of Pompeii may be the result of errors in the rectification of the original aerial images and differences projected between coordinate systems (PBMP data are in the Monte_Mario_Italy_2 projected coordinate system). On the creation of the RICA Maps, see Van der Poel, H. B., Corpus Topographicum Pompeianum, vol. IIIA. Austin, TX, 1986, XI-XIX. Symbologies: This feature class is symbolized as quantities (graduated colors) in five manually derived classes, with no display transparency, and scale visibility set to not above 1:40,000. Credits: These data were produced by Eric Poehler for the Pompeii Bibliography and Mapping Project after original CAD data provided by the Soprintendenza di Pompei.
