As advances in technology find their way into the maintenance activities of departments of transportation, traditional methods are being challenged with innovation. The struggle results in finding a balance between applying past methods that have shown results and using new advanced technology to optimize resources. The issues that are prevalent implementing new and innovative technology in maintenance operations are very similar to deploying intelligent transportation systems (ITS). This paper details these challenges and presents resolutions for addressing these concerns. The paper is based on the findings of a project sponsored by the multinational Aurora consortium and exchange of information among members. One significant issue is that technology-based methods of resolving operations and maintenance problems may meet resistance from staff familiar with conventional, proven methods of performing their duties. Another issue is that deployment of new technology involves considerable investment in training to ensure proper results. The inability to effectively use a system as a result of lack of training creates frustration and loss of faith in the system. Furthermore, the cost of equipment is another issue. With funding for projects already spread thinly across various interests, the competition for funds remains fierce. Public agencies are seeking partnerships with the private sector to share costs for implementing and operating traditionally "public" responsibilities. The Aurora-sponsored project found that, particularly with Road Weather Information Systems (RWIS), the proprietary nature of new technologies tends to hold public agencies to using equipment from a single vendor. This is a concern because, ultimately, the benefits of deploying RWIS are most visible when the technology is implemented as a statewide network. The same will be true with ITS deployments. This issue can be resolved with standards and protocols, but they are slow in emerging. Although there are many challenges, recognizing their existence is the first step in resolving these issues. |
