Telvent to Implement Its Toll System On Three Brazilian Highways

MADRID, Spain, April 10, 2008 (PRIME NEWSWIRE) -- Telvent (Nasdaq:TLVT), the IT
company for a sustainable and secure world, announced today that it will be in
charge of supplying, installing and starting up its SmartToll system on three
federal highways in Brazil. This project, valued at more than eight million
euros, will be executed in less than a year. With this new system, Telvent will
contribute daily to improving road safety for more than a million and a half
automobiles.

The OHL Brasil construction company, which currently holds the most kilometers
in Brazilian highway concessions, has entrusted Telvent to implement its toll
collection system, which will entail the installation of 19 toll booths, three
control centers (one per toll road), 348 tollways (of which 80 will be
automated), as well as Telvent's SmartToll management software. Through this new
contract, Telvent adds 1,200 kilometers to the 3,500 kilometers already under
the Company's management in Brazil.

Jose Montoya, Executive Vice-President of Telvent's Transportation division, has
expressed his satisfaction with the contract award: "We appreciate the trust
that OHL Brasil has on Telvent. We hope to be able to continue collaborating in
future projects. By obtaining this new contract in Brazil we reinforced our
growth prospects in the country and we contribute to improve the security of its
roads."

Toll control systems will be installed in the Fluminense highway, connecting Rio
de Janeiro to Vitoria, the Fernao Diaz highway, connecting Sao Paulo to Belo
Horizonte, and the Regis Bittencourt highway, connecting Sao Paulo to Curitiba.

Telvent carries out numerous projects in Brazil, among which the following stand
out: highway management, ticketing systems, the UTC development and maintenance
in Rio de Janeiro, Sao Paulo and Belo Horizonte, as well as the control system
for the storage terminal in Suape, and the SCADA water distribution management
