The concept of "unintended consequences of policy decisions" is introduced as one potential outcome of the implementation of transportation policy. An unintended consequence is one that diverges from an authorized or directed policy action. This concept is illustrated by an assessment of the short-lived transportation management systems mandate in the Intermodal Surface Transportation Efficiency Act of 1991. Policy implementation theory suggests four propositions as an assessment framework: intergovernmental linkages, communication between linkages, organizational capacity of the implementing agency, and interpretation of the policy message. Problems in all four elements contributed to unintended consequences of the management system mandate and its eventual reversal in 1995. Implementing transportation policies and mandates has become increasingly complex; a more informed understanding of the policy-making process, and the conditions under which unintended consequences can occur during the implementation stage, will influence better policy design and implementation efforts. |
