9 Each Stretch is divided in substretches located between two consecutive nodes (interchanges) Issues Addressed The Project AEDL was installed according to Technical Instructions of National Road Authority, EU Standards and other documentation including the EasyWay Deployment Guidelines. The Project includes command and control, traffic counting and classification, video monitoring, automatic incident detection, road emergency call boxes, variable message signs, tunnel management, weather stations, automated event management and automated traffic management subsystems

10 3. Description of the ITS Project 3.1. Service Area For the Project Traffic Control and Management System in AEDL BRISA Group the EasyWay Service Areas are: Traveller Information Services Traffic Management Services, ICT Infrastructure, 3.2. Key Words Key words to describe the nature of the project and the applications used are: Traveller Information Services Pre-trip Traveller Information On-trip Traveller Information Variable Message Signs Driver Behaviour Traffic Management Services Variable Speed Limits Automatic Incident Detection Use of CCTV Traffic Management using Rerouting ICT Infrastructure Traffic Management Plans Traffic Monitoring Control Center 3.3. Objectives For this project the objectives (EasyWay objectives and objectives of the project Sponsor) are as follows: Improvement in road safety Decrease in congestion, facilitate travel and mobility of people and goods Reduction in the impact on the environment 3.4. Systems and Technologies Applied ROAD SIDE SYSTEMS The systems installed in the road side were: Vehicle counting and classification system (CT \ SCCV) Variable Message Signs system (VMS)

11 Video-surveillance system (CCVT) Weather Station Meteorological system (EM \ WS) Emergency call box system (SOS) Tunnel control system The vehicle counting and classification equipments (CT \ SCCV) were installed in each substretch between each pair of consecutive nodes and are able to collect all suitable traffic data, including the following variables: Average speed, traffic volume, intensity Number of axles and distance between axles Instantaneous speed and classification of each vehicles. Two of these equipments are also prepared for weighing in motion (EPD \ WIM). Each variable shall be reported by lane and direction and the automated traffic data collection subsystem shall ensure the collection of data per lane of each Substretch. Figure 3 : SCCV road sensors on a site of A32 The variable message signs (VMS) subsystem contributes to an accurate and effective tactical management of traffic and complements this priority function with the installation of equipment permitting the strategic management of traffic. Each VMS includes one graphic area (48x48 RGB) on the left side and one alphanumeric area (3 lines with 18 characters of 320mm)

12 Figure 4 : VMS in A41 The CCTV cameras were installed at each interchange and also between two interchanges depending on the length of the substretch, thus covering the main points of the concession. Figure 5 : CCTV Camera and weather station at A

13 The weather stations were installed in specific locations and supply meteorological information about the weather conditions, including: Air temperature and relative humidity Wind speed and wind direction Present weather and visibility Road surface status Barometric value Figure 6 : Weather Station in A41 The emergency call boxes (SOS) are installed in both directions every 2 km in all the stretches of the network 1 and

14 Figure 7 : SOS emergency call box in A TUNNEL SYSTEM The AEDL Project included the installation of telematics systems in two new tunnels included in the concession: The Covelo Tunnel in A41, circa 600 meters long, with two galleries of 3 lanes each The Seixo Alvo Tunnel in A32, circa 400 meters long, with two galleries of 2 lanes each The Covelo Tunnel in A41 received the following telematics systems: Video-surveillance cameras Emergency call boxes near the entry, in the middle, and near the exit Lane control at the entry gates Technical management (local and remote) The Seixo Alvo Tunnel in A32 received the following telematics systems: Video-surveillance cameras Emergency call boxes near the entry, and near the exit Lane control at the entry gates Technical management (local and remote) These systems complemented the other tunnel infra-structure systems including illumination, ventilation, and fire detection and fire extinguishers

15 COMMUNICATIONS SYSTEM The communications system used in this AEDL project is based on a two level network with optical technology, using a 1 st level backbone structure between main points including the Traffic Control and Management System and a 2 nd level access structure connecting all the road side equipments. Each one of the two road networks has independent communications system.

17 The ITS systems installed in this project are operated by the main Traffic Control and Management Centre of the BRISA Group existing previously installed in Carcavelos (A5). Figure 11 : Main Trafic Control and Management Centre of the BRISA Group in Carcavelos (A5) Additionally a second videowall and one ITS telematics server was installed in the Control Room of Estradas de Portugal, the Grantor, to allow this one to operate network 2. All the ITS equipments are operated with the software ibrisa\atlas that was developed by BRISA, which allows access to all data collected and control of all roadside equipments with a web-browser. The following pictures shows some examples of the operation of the ITS equipment with the ibrisa\atlas software
