# Highway system of São Paulo

The highway system of São Paulo is the largest statewide road transportation system in Brazil, with 34,650 km. It consists of a hugely interconnected network of municipal (11,600 km), state (22,000 km) and federal (1,050 km) roads. More than 90% of the population is within 5 km of a paved road.
It has also the largest number of two-, four- and six-lane highways in Latin America. According to the National Confederation of Transports, it is the best highway grid in the country, with 59.4% classified as excellent.
The term used in Portuguese language for highway is rodovia, and for road is estrada.

## Management systems

The responsibility for building, maintaining, expanding, managing and exploiting the state roads fall into the following categories:
* DERSA Desenvolvimento Rodoviário S.A. A state-owned company, responsible for some state-built roads and highways, such as Rodovias Dom Pedro I, Carvalho Pinto, Ayrton Senna, etc. (see below for the names and specific information about highways);
* DER Departamento de Estradas de Rodagem. A state department belonging to the State Secretary of Transportation;
* Ministry of Transportation, responsible for the federal highways and roads crossing the state, such as Rodovias Presidente Dutra, Régis Bittencourt, Fernão Dias, etc.;
* Municipalities, responsible for vicinal roads and roads within counties.
* State concessions to private companies.
By the law nº 9.361, of July 5, 1996, the state government implemented a comprehensive program of privatization and public concession of highway infrastructure management and economic exploitation (Programa Estadual de Desestatização - State Program of Desestatization), whereby most of the highways under the tutelage and built by the state began to be managed by private companies. In order to implement the Program, the highway grid was subdivided into 12 sections, with a total of 3,500 km, interconnecting 198 counties with a population of approximately 20 million inhabitants (54% of the state's population).
The following 12 companies were contracted under a public bidding system:
* AutoBAn, (owned by CCR S.A.)
* Autovias, (EixoSP, owned by Obrascón Huarte Lain)
* Centrovias, (EixoSP, owned by (Obrascón Huarte Lain)
* Colinas
* Ecovias
* Intervias
* Renovias
* SPVias, (owned by CCR S.A.)
* Tebe, (TEBE S.A.)
* Triângulo do Sol
* Viaoeste
Until August 2005, these companies had invested R$ 6 billion (approximately US$ 2,5 billion) and generated a revenue of R$ 2 billion for the state. The concessions led also to the duplication (double laning) of more than 480 km and the construction of 110 new roads. All conceded highways are equipped with fixed emergency phones every 1 km, horizontal and vertical signalling equipment, surveillance cameras, and round-the-clock, free-of-charge mechanical and emergency relief vehicles. which make São Paulo highways the most sophisticated and with the highest safety and service standards of Latin America.
All conceded roads, including those managed by DERSA, are toll roads, in order to pay for the services and investments. Roads managed by the state (DER) are generally not tolled. Toll collection is made in toll gates spaced along the road. Sometimes tolling occur only in one direction of the road, in other cases, in both directions. Toll pricing is set by the State Secretary of Transportation and vary from US$ 1 to US$ 4.
The entire São Paulo system of highways (16 in the total) use a unified non-stop electronic toll collection named "Sem Parar", based on RFID tags glued to the vehicle windshield, which comprises about 34% of the traffic through these roads. The system has 560,000 of these tags installed and generates 11 million of electronic transactions and revenues of ca. R$ 120 million (approximately US$ 52 million) per month.

## Naming and numbering system

Within São Paulo, numbering of highways works as follows, starting with letters SP:
* even numbers - indicates that the highway is radial, that is, connects the state capital to the interior. The number of the highway gives the clockwise angle that it makes with an imaginary line stemming from the state capital and extending northward. Thus SP-270 (Rodovia Raposo Tavares) starts in São Paulo and extends westward (thus a 270-degree clockwise angle with the imaginary north-extending line). Example: Rodovia Anhangüera, SP-330.
* odd numbers - indicates that the highway connects two or more places away from the capital. The number gives the distance, in km, between the capital and the nearest point of the highway. Thus, SP-425 (Rodovia Assis Chateubriand) connects two cities away from the capital, and its nearest point is distant 425 km from the state capital.
It is customary in Brazil, and particularly in São Paulo, to give also official names to the highways and roads, usually to pay homage to some politician, significant personality, national hero, etc., or to some symbolic or collective concept.
