It takes between 45 minutes and 1 hour to travel from Porto to Aveiro, using either the A1 or the A29 highways. Travelling from Lisbon will take about 2 hours, using either the A1 highway or, best choice, the A8 and A17 highways.
Pay attention to Electronic Tolls: Some highways in Portugal have electronic tolls exclusively. This means that there are no cabins and the electronic identification of the vehicle is made at the moment of crossing the point of collection, in one or several sites along the highway. All lanes with electronic tolls are properly identified using the reference "Electronic toll only". You can enter but you have to pay the tool in the next 5 business days on a post office. For more informations regarding this system please go to Portugal Tolls or contact your can rental company.
There is a free parking lot next to UA's water tower building (GPS coordinates: N 40 37.733, W 8 39.300) and it's possible to find other parking locations around the Campus, however it's more advisable to leave the car at the Hotel and walk to the University, since the majority of the hotels are within a comfortable walking distance. See the Walking Map of Aveiro to have an idea of the distances inside the City.
