Developing Notification and Enforcement Systems to Communicate and Administer Bridge Load Postings

项目名称：	Developing Notification and Enforcement Systems to Communicate and Administer Bridge Load Postings
摘要：	State and local law enforcement agencies in the US strive to enforce weight restrictions on trucks and heavy vehicles travelling on public roads as a matter of public safety and as a way of safeguarding vital transportation infrastructure. For instance, vehicles over 40 tons are not permitted on interstate highways under normal conditions. Moreover, other restrictions can be applied based on the legal load combination, a function of vehicle weight and axle spacing. The Louisiana Department of Transportation and Development (LADOTD) has a total of 13,000 bridges: 8,000 on-system bridges (state-owned) and 5,000 off-system bridges (local entity owned) which require significant resources to maintain and replace. In general, bridge owners have three critical tasks in common: inspect the bridge for deterioration or damage; determine if changes in condition have reduced the bridge’s structural capacity to safely carry legally permissible loads, measured by its load rating; and notify the public of any weight restrictions. Unfortunately, the bridge infrastructure is deteriorating faster than resources will allow for rehabilitation and replacement. As bridges deteriorate/age and live load increases due to industry demand for larger and heavier trucks, the load carrying capacity of the structure decreases, therefore load posting is required to ensure public safety. Therefore, the main objectives of this research are to: (1) Identify plausible notification systems that effectively communicate bridge load postings to dispatchers and drivers. (2) Investigate and suggest possible approaches to communicate potential detour routes. (3) Identify corresponding enforcement methods required to successfully administer bridge load postings. It is expected that the outcomes of this research will assist in improving traffic safety in Louisiana by developing a mechanism to communicate and enforce load restrictions on bridges. This is crucial to provide the appropriate level of safety for those utilizing these bridges especially on daily basis.
