Access control systems in Rome

The full-scale deployment of automatic access control systems in Rome has tackled a number of issues, ranging from the technical issues, to the management issues, and to a variety of bureaucratic and institutional issues.

Basic instrument for safeguarding Rome’s historic city centre (Limited Traffic Zone) is the installation of electronic gates for traffic monitoring and control. Historic city centre LTZ subsystem, operating from October 2001, includes the use of 22 gates on access roads to historic city centre that optically detect the plate of vehicles by APNR (Automatic Plate Number Recognition) techniques. They also control, according to the plate number, if vehicle is licensed or not to enter, and in case of eventual offence, they switch on the procedure of sanctioning according to rules in force. The 22 historic city centre LTZ gates also use short-range radio technologies (DSRC) for communication.

Thus, vehicles are identified through an exchange of information via radio between the gate (RSU Road Side Unit) and a device called OBU (On Board Unit) that is inside the vehicle. LTZ of Rome historic city centre is prohibited to cars during working days from Monday to Friday from 6.30a.m. to 6p.m. and Saturday from 2p.m. to 6p.m..On Friday and Saturday LTZ is also operative from 11p.m. to 3a.m. Following the good results obtained by the historic city centre LTZ, it has been installed a new Limited Traffic Zone, Trastevere LTZ. It consists of 12 gates along all the roads entering the area.

Trastevere LTZ subsystem came into service on 26th July 2006 and it includes the monitoring of entries only by optical system. An important innovation was the installation of variable message signs near the gate. The signs indicate to users the operating state of the gate. These will soon be extended on all historic city centre LTZ gates.

Trastevere LTZ works from Monday to Friday from 6.30 a.m. to 10 a.m. and on Friday and Saturday night from 9 p.m. to 3 a.m.

In the next few months 10 new electronic gates will be installed for monitoring other two LTZ areas named San Lorenzo LTZ (7 gates) and Villa Borghese LTZ (3 gates).

- Daily average of entries 130.000
- Average of entries in working times (6.30a.m. - 6p.m.) 70.000
- Daily average of offences (7% of the entries) 5.000

- Reduction of access flows -15/20%
- Increase of average speed (in LTZ) + 4%
- Increase of public transport average speed (in LTZ) +5%

LTZ access for authorised categories is based on an annual permit worth the equivalent of a 12-month public transport card (311.47 Euro) now increased by a new Council Act, where the cost for permit becomes 550,00. Authorised categories can also use a per day permit, whose cost is 20,00.
