The Structure


Inter-dependencies between COLOMBO work packages

COLOMBO is divided into "work packages" (WPs) where certain aspects of the overall solution are treated. The research and development is performed in the following work packages:

  • WP1: Low Penetration Rate Cooperative V2X Traffic Surveillance
  • WP2: Self-Organizing Traffic-Light Control System for low Penetration Rates
  • WP3: Automatic Algorithm Configuration and Tuning
  • WP4: Optimisation of Energy Consumption and Emissions
  • WP5: Simulation Tools and Evaluation

Two further work packages are concerned with the dissemination of generated knowledge and with the management of the project, respectively:

  • WP6: Dissemination and Exploitation
  • WP7: Project Management

Each of the work packages is again divided into smaller "tasks", representing steps towards achieving the goals.

The evaluation scenarios developed in WP1, Task1.1 will be used in later research within work packages 1-5 for evaluating the developed algorithms. Within WP5, Task5.3 these scenarios will be embedded into an evaluation system for traffic lights, yielding in a re-usable, well-defined system for evaluating a traffic light system’s performance. The results of data collection methods developed in Task1.2 and Task1.3 will be used in WP2 as measures consumed by the traffic light control developed in WP2. WP2 will additionally use the configuration system developed in WP3 for choosing the best policies. WP4 supports a model for emission computations, used in work package 5 for determining the environmental impacts of the developed solutions. WP5 supports the traffic simulation which interacts with the developed systems, allowing to a) retrieve values from the simulation for being used for traffic state determination, b) change the simulation in accordance to the developed traffic light system’s propositions, and c) to produce measurements for valuing the results.

WP6 collects the results obtained within the work packages 1-5 for their dissemination. WP7 controls the overall process.

WP1: Low Penetration Rate Cooperative V2X Traffic Surveillance

This WP is dedicated to the development of self-organizing solutions for traffic surveillance which gather data from on-board vehicle devices, such as vehicular communication (V2X) systems or PDAs. The work includes (i) the determination and specification of measures that can be collected, (ii) the development of self-tuning algorithms for data collection and fusion taking into account different sources and different vehicle classes, including conventional stationary detectors, and (iii) the evaluation of self-organizing opportunities to disseminate information obtained from data fusion to incoming vehicles and traffic management facilities. Based on collected data, solutions for incident detection and local emissions modelling will be developed and evaluated. A strong focus will be put on the systems functionality at even low penetration rates. This WP will also deliver a comprehensive set of evaluation scenarios to be used in subsequent steps across other work packages for evaluation purposes.

WP2: Self-Organizing Traffic-Light Control System for low Penetration Rates

This WP is devoted to the design and implementation of a self-organizing, adaptive and sensor-aware traffic light control system, based on the concepts of emergent behaviour and swarm intelligence. The outputs generated by the traffic surveillance methods developed in WP1 are used in WP2 as an input to the traffic light controller. A set of policies specified by experts will be designed for particular traffic conditions such as low, medium, high traffic density, congested traffic as well as for pedestrian crossings, bicycles, public transport. A dynamic probabilistic policy selection algorithm based on sensor input will be implemented along with a learning mechanism for adapting to drivers behaviour.

WP3: Automatic Algorithm Configuration and Tuning

The primary goals of WP3 are (i) to provide the tools and algorithms for an automatic offline configuration of the traffic lights control developed in WP2, (ii) to provide means for the online adaptation of strategy parameters and (iii) to optimize the traffic light controllers using offline and online configuration tools based on a simulation-based optimization. The secondary goal of WP3 is to give service to other work-packages where algorithmic tools are used that need to be appropriately configured for optimizing their performance.

WP4: Optimisation of Energy Consumption and Emissions

One part of this work package is devoted to extend the involved PHEM emission model by vehicle classes for the year 2020 population for predicting long-term impacts of the developed systems. Additionally, a model of a pollutant emission reducing driver behaviour will be developed. Within this WP, PHEM will be coupled to the used traffic simulation SUMO. Finally, a guideline for developing ecological friendly traffic light systems is generated.

WP5: Simulation Tools and Evaluation

This task integrates the sub-systems and algorithms developed in WP1-4 into a single execution system. Besides this, the used open source traffic simulation SUMO will be extended by pedestrian and bicycle traffic in order to improve the representation of traffic at controlled intersections. The execution system will be used to measure the performance of the traffic surveillance / traffic control systems developed in COLOMBO. Based on scenarios generated in WP1, a generic and sustainable traffic light control evaluation schema will be established. For the evaluation of configurations, increasingly advanced versions of the simulation and evaluation tools developed in this project in WP5 will be used.

WP6: Dissemination and Exploitation

The goal of WP6 is to organise the dissemination and further the exploitation of the results of the project. The approach is two-fold. Firstly, the classic approach of publications and presentations at suitable conferences will be used. Secondly, an Advisory and Dissemination Board (ADB) consisting of stakeholders will be active during the whole duration of the project, organising open workshops for stakeholders at key moments in the project. Further dissemination material (web-site, brochure) will be set-up here.

WP7: Project Management

The main management activities – communication between partners, European Commission, and across work packages; coordination, monitoring, and reporting; meetings organisation; legal, financial and administrative management – are collected in WP7.
