The next model in the development phase towards outsourcing of routine maintenance activities is called the "Activity Based Maintenance Model" or what is now coined as the "Salesman Model". This model refers to those road authorities that outsource various routine maintenance activities. The reason can be either to balancing the work load, not having the resources, or work can be more efficiently performed by the private sector. This "Sales-man Model" is usually based upon the lowest price, based upon unit prices (sometimes hourly rates), and usually for 1 year or seasonal duration. The activities vary and have been typically utilized for snow removal (winter maintenance), grass mowing, line marking, rest areas, cleaning activities, sanitary works (trash removal) and other routine activities. Even resurfacing contracts are considered in this model.
Almost all road authorities at some point in time have used this type of contract to meet the maintenance requirements and most countries will continue to use this model.
