Can we make assets and infrastructure last longer, given tight DOT budgets and increased demand? Every unit of distance traveled by a loaded “18-wheeler” causes over 9000 times the road wear of a light-duty vehicle. Congested roads escalate delay, emissions, and other costs, impacting community health and resilience. London and Sweden decreased demand with bicycling improvements and congestion charging. This session will consider current technology pathways alongside the demand pathways and a re-emphasis of approaches in a period of uncertainty.



How do we make our roads and infrastructure last longer, given tight budgets and all the demands DOTs face?  Every avoided trip is worth something to DOTs, whether it be their maintenance obligations or the ability to provide a reliable transportation system.  Los Angeles DOT is exploring implementing Infrastructure as a Service, with better road costing, perhaps through VMT charges. Every unit of distance traveled by one properly loaded “18-wheeler” causes over 9000 times the road wear of a light duty vehicle.  In addition usage that adds congestion to roads escalates delay and emissions and other costs, impacting health and resilience.  The first (delayed) driver in 5 miles of crawling traffic doubles his emissions, and this is about equal to the extra pollution he causes with the cars behind him.  London and Sweden have effectively brought down demand with bicycling improvements and congestion charging. Now, with technology changes like AVs and EVs in the pipeline, along with shared vehicles, what kind of demand are we planning for? What kind of demand could we need to plan for (higher or lower) and what is shaping that?  This session will consider whether we are on track with the technology pathways alongside the demand pathways and suggest if we need a rethink or re-emphasis of approaches or whether we are just in a period of uncertainty.  How will this affect DOT maintenance?
