Infrastructure in Navenna

Because of the country's location at the Mesembric Ocean and long coastline, Navenna has well developed maritime infrastructure for the transportation of passengers and goods.

Road transport

Autostrade

Navenna's autostrade, equivalent to the Ingrean term motorway, form the network of the most important long distance roads in the country. Autostrade are reserved for high speed motorized traffic and pedestrians, cyclists, mopeds or other slow vehicles are prohibited. Autostrade have a uniform minumum standard defined in the Navennese traffic code - separate carriageways for each direction of traffic, at least two lanes in each direction, hard shoulder to the right side of the direction of travel, controlled access, grade-separated intersections and acceleration/deceleration lanes for traffic entering/exiting the autostrada respectively. Autostrade have a standard speed limit of 130 km/h (80 mph) but speeds are commonly lowered near cities and along high volume sections. Speed limits are also regulated dynamically along sections with active traffic management, which also feature variable information signage that can display information about driving conditions, traffic accidents, road works and estimated driving times based on current conditions. Most autostrade have rest areas located at regular intervals along the road that are only acessible from the autostrada.

Autostrade are managed and maintained by private companies who are assigned sections through public procurements. Concessions are granted by the Navennese Ministry of Infrastructure and Mobility. All autostrade are tolled, with the exception of a few short sections around the City of Navenna where the A-1 and A-5 terminate. Toll collection is with few exceptions organized as a closed motorway system where drivers pay based on the distance travelled. Tolls are collected at toll plazas at motorway exits either with drivers stopping at a booth and paying manually with cash or card, or using a detection lane to pay electronically using an on-board transponder. Manual payment is planned to be gradually phased out in favor of using the current transponder system or a new system using cameras reading the license plates of passing cars without transponders and sending a payment request to the registered owner of the vehicle.

Due to the country's small size, few autostrada route numbers are actually in use. The route numbers 1-6 are used for autostrade in the vicinity of the City of Navenna and are arranged in a rough radial system from west to east, while the numbers 7-19 are reserved for main routes in other parts of the country. Many route numbers are reserved for hypothetical routes that have planned itineraries but lack any traffic demand to justify their construction. A-2 is reserved for a future autostrada replacing the current N-6 between City of Navenna and Guinevento. A-6 was reserved for an autostrada connection across the mouth of the river Cesi to the densily populated barrier island east of the city, but plans for such a route was scrapped due to strong public opposition and concerns over ecological effects on the already strained ecosystem in the Navennese lagoon. Spur routes are numbered based on which trunk routes they connect. Only one such spur exists, A-51, which is numbered so due to being a short route connecting A-1 with A-5. The A-13 is about the same length as the A-51 but is part of a longer planned route and is thus not considered a spur.
