2 years ago In 2016, Argentine mappers standardized on network=AR:national for national routes, network=AR:provincial for provincial routes, and network=AR:national:secondary for secondary provincial “routes”. (I haven’t seen any evidence that there are signposted secondary provincial routes; they actually seem to be secondary road inventory numbers rather than route numbers.)
In January 2021, one user switched quite a few provincial and provincial secondary routes over to a hierarchical format: AR:X or AR:X:secondary, where X is the province’s ISO 3166-2 code. This reflects the fact that provinces do not coordinate route numbering with each other, but there’s no documentation about this practice, other than a 2016 suggestion on the forum that was rejected in favor of the basic format. Unless the community affirms its acceptance of the hierarchical format, we should only support the one that’s documented on the wiki and somewhat more prevalent.
Unfortunately, virtually all ref tags on national and provincial route relations are prefixed with “RN” or “RP”, which is how the routes are identified on kilometer posts but not on shields. These prefixes are redundant on relation refs because network already distinguishes between national and provincial routes. Consistent with how the ref key has been documented for many years, this project intentionally doesn’t perform postprocessing on relation ref tags. In order for shields to look correct, the “RN” and “RP” prefixes will need to be removed from the relations’ ref tags while keeping them on the ways’ ref tags. For example, on autopistas, “RNA” would become “A”.
El 2016, los mapeadores argentinos estandarizaron las etiquetas network=AR:national para las rutas nacionales, network=AR:provincial para las rutas provinciales, y network=AR:national:secondary para las “rutas” provinciales secundarias. (No he visto nada evidencia de que haya las rutas provinciales secundarias señalizadas; de hecho parece que son números de inventario de caminos secundarios en lugar de los números de ruta.)
El enero de 2021, un usuario cambió muchas rutas provinciales y provinciales secundarias a un formato jerárquico: AR:X o AR:X:secondary, donde X es el código ISO 3166-2 de la provincia. Eso representa que las provincias no coordinan los números de ruta entre sí, pero no hay documentación sobre este uso, aparte de una suregencia que el foro rechazó en 2016 en favor del formato básico. A menos que la comunidad afirme el formato jerárquico, solo debemos apoyar el que aparece en la documentación en el wiki y es un poco más prevalente.
Desafortunadamente, prácticamente todas las etiquetas ref en las relaciones de rutas nacionales y provinciales incorporan el prefijo “RN” o “RP”, como en los mojones kilométricos pero no como en los escudos. En las relaciones, estes prefijos de ref duplican la etiqueta network que ya distingue entre las redes nacionales y provinciales. Según la documentación de la clave ref, este proyecto intencionalmente no postprocesa las etiquetas ref en las relaciones. Para que los escudos sean correctos, los prefijos “RN” y “RP” deben ser eliminados en las relaciones mientras que son preservados en las vías. Por ejemplo, en las autopistas, “RNA” se converterían en “A”.
Argentina’s national and provincial routes should be marked with shields that reflect the standard designs on directional signs. National routes are marked by a black-on-white pentagonal shield, while provincial routes are marked by a black-on-white rectangular shield.[^class] These designs are specified by the Manual de Señalamiento Vertical (2007). These simple shapes appear on both directional signs and as reassurance markers affixed to distance signs:
National routes also have a more elaborate shield for standalone reassurance markers, featuring the province’s name, “RA”, and the national flag. In some places, an oversized variant of this shield is even posted for tourists to take selfies with. Nonetheless, the simpler shapes are all that’s needed on a map, as this signposted map demonstrates.
All provincial route shields look alike and lack any indication of the province, but route numbers are only unique within a given province.
[^class]: There is a parallel system of classifying roads as trunk, secondary, and tertiary that is not reflected on signage, as far as I can tell; however, trunk roads carry national routes, and secondary roads carry provincial routes.
