SHRP 2 L11: Final Report<br />

focuses of the 2010-2014 U.S. Department of Transportation ITS Strategic Research Plan is <strong>to</strong><br />

fully develop the capabilities of Vehicle Infrastructure Integration (VII). Existing applications are<br />

mostly based on the need <strong>to</strong> survive a crash, whereas future applications will focus on the ability <strong>to</strong><br />

avoid a crash. Future vehicles will supplement or override driver control when necessary. The<br />

integration of several technologies will make the communication of vehicles and infrastructure<br />

possible.<br />

In the same line of technologies, the concept of shared smart cars will also be part of most urban<br />

areas and large-scale-trip-attracting developments such as airports and amusement parks. In these<br />

applications, the share smart car concept makes carpooling and conventional transit more effective,<br />

by solving the "last mile” problem.<br />

Regarding renewable fuel sources, the increase in electric and hybrid vehicles will follow the<br />

changes in funding sources. The additional cost associated with <strong>to</strong>ll roads and congestion pricing<br />

on the <strong>to</strong>p of gas taxes will lead <strong>to</strong> a shift from fossil-based vehicles. Hydrogen fuel will also<br />

appear as an environmentally friendly alternative <strong>to</strong> fossil-based fuels, especially in Europe and<br />

Asia. In North America, bio-diesel consumption will be widespread and will help offset the pricing<br />

costs for roadway users.<br />

In addition <strong>to</strong> technological innovations, future concepts of “smart” and “compact” growth and<br />

transportation planning will emerge. Integrated technologies will support this vision of the future,<br />

but, the integration of ideas and lifestyle rethinking will be the main drivers of this visionary<br />

future. As noted earlier, web and mobile applications will be the roadway user’s comprehensive<br />

data and information center. Radical changes in land-use patterns will be observed. Commuters<br />

will live closer <strong>to</strong> job locations and related activities. With the full deployment of telecommuting<br />

capabilities, suburban areas will see more “business centers” where workers that live nearby will<br />

go <strong>to</strong> work, regardless of their employer location. Government will also support people living<br />

within a certain distance of their place of employment. With that, miles traveled between jobs and<br />

housing will reduce dramatically, having a positive impact <strong>to</strong> travel-time reliability.<br />

The least-sustainable suburban communities will be redesigned in<strong>to</strong> work-leisure areas where<br />

“community-gathering” spaces will be created nearby residential neighborhoods. Walkable social<br />

activities will transform once old cheap land in the suburbs. (11) The actionable future needs <strong>to</strong><br />

combine multimodal transit, telecommuting, ridesharing, demand management, land use, market<br />

forces, pricing policies, technology, and a mind shift in roadway users’ approaches <strong>to</strong> traveling.<br />

In the future, ITS will need <strong>to</strong> inform and assist all trips imaginable on all roads and via all modes<br />

of travel. All of the elements needed <strong>to</strong> make driverless cars – radar, au<strong>to</strong>matic pilot software,<br />

computing power, wireless communications and, of course, navigation systems that know where<br />

you’re going are technologically feasible, and in many cases are even available commercially.<br />

Even without collective action, driverless technology will advance. The reason is that decades of<br />

experience have shown that we will pay for car safety. It is not hard <strong>to</strong> envision a gradual<br />

(12, 13)<br />

evolution as computers stealthily take on more and more of the driving chores.<br />

In the future, bicycles will play an important role on improving mobility. Dynamic routing, bike<br />

sharing and distributed data sensing are some of the innovations that will take place in order <strong>to</strong><br />

give roadway users comparable technology and information available across different modes. A<br />

trip <strong>to</strong> the grocery shop will no longer involve one mode of transportation only. Shared used of<br />

different modes will allow the shopper <strong>to</strong> use public transportation or lighter personal<br />

transportation (scooters, bicycle…) <strong>to</strong> go shopping and then use a smart car <strong>to</strong> bring bags back<br />

home. The following path will be a reality:<br />
