The Dublin Transportation Office (DTO) is to carry out an audit of cycle and bus lanes in the Greater Dublin Area and surrounding towns.
The audit will include networks in Wicklow town, Arklow, Naas, Navan, Athy, Drogheda and Trim.
The DTO has advertised for companies across Europe to tender for the contract.
Along with collecting details on the position and number of cycle tracks and bus lanes, the successful consultants will be required to collect information on parking next to the lanes, traffic signals and notable hazards and features.
Some 4,500km of road will be studied as part of the audit, including an estimated 250km of cycle lanes and 170km of bus lanes.
In its tender documents the DTO said the estimated lengths were only guide figures, and the true lengths may be substantially more.
The information collected will be used to create an inventory of cycle and bus lane facilities in the Greater Dublin Area, and will be held by the DTO in an electronic database.
It will be used to assist in identifying areas for improvement and for new cycle and bus network measures.
The DTO has said it would maintain the database, and local authorities and other implementing agencies would provide it with information updates.
A spokeswoman said the audit would map exactly where the tracks and lanes were with a view to producing public literature.
"They will also check the condition of the cycle lanes so that the relevant local authorities can be contacted and the repairs carried out where required.
"The cycle tracks can be patchy; we want to make sure we have a total map of where they are. We are looking at it with a view to what can be done to improve facilities for cyclists in the GDA and to encourage cycling."
The closing date for tenders is March 9th.
