Control in Road

ControlInRoad - Controlling the spread of invasive species with innovative methods in road construction and maintenance.

In this project, engineers and researchers, experts from different disciplines, formed a consortium to develop and evaluate methods to prevent the spread of invasive alien plant species during road construction and maintenance.

Invasive Alien Plant Species (IAP) are a threat to biodiversity. Transport infrastructure habitats play an important role in facilitating the spread of IAP by providing an ideal habitat for their establishment and actingn as corridors for spread.

To control IAP the project will:

  1. Compile a list of IAP related to roads for selected European countries.
  2. Test new methods of IAP management
  3. Develop a best practice guide for road construction and maintenance
  4. Create a cost-benefit analysis for best practices


This survey addresses national and international experts with knowledge on the problem of invasive species or are interested in it for other reasons..

AIMS of the survey:

1. Create AWARENESS on the problem of invasive alien species during road construction and maintenance

2. ASSESSMENT of current KNOWLEDGE on:
     a. Invasive species
     b. Existing laws, standards and routines

     a. Possible problems caused by invasive species on road
     b. Measures to control invasive species in road construction and road maintenance

Areas of research

  • Invasive alien species related to roads in Europe
  • Evaluation of methods in vegetation management
  • Best practice guide
  • Cost benefit analysis


ControlInroad is financed by the CEDR Transnational Road Research Program Call 2016 “Biodiversity - Conflicts along the Road: Invasive Species and Biodiversity” with funding provided by the road administration of Austria, Germany, Ireland, the Netherlands, Norway, Sweden and Slovenia. The programme is being managed by the Rijkswaterstaat Water, Verkeer en Leefomgeving, Netherlands on behalf of CEDR. The Programme Executive Board (PEB) is chaired by Reinhard David, ASFiNAG, Austria.
