Evaluating Alternative Operations Strategies to Improve Travel Time ...

SHRP 2 L11: Final Report
• Predictive models for real-time systems operation
Integration/Cooperation
• Customized, real time routing
• Multimodal routing, schedules, trip planning
• Real time information on parking availability, roadway conditions, routing, rerouting
• Rapid incident clearance
• Latest onboard technology
• BRT and signal pre-emption
• Universal fare instruments for transit and road pricing
• Real time condition monitoring to predict long term infrastructure performance
• Combined sensors/ computer/ wireless link
• Advanced Automated Crash Notification Systems (AACN) in all vehicles
• Next Generation 9-1-1 fully implemented
• Hybrid Wireless Mesh Networks
Innovative technologies will support the following actions:
• Optimal routing and matching of supply and demand
• Real-time knowledge of departures and arrivals and travel times and congestion
• Dynamic, market-based pricing
• Funding that more accurately matches network user choices
• Improved relationship between land use and transportation
• Understanding and measuring congestion externalities
• Parking reductions
• Carpooling initiatives
• Improved dissemination and sharing of transportation information
• Street design for multimodal use
• Increased transit, bicycle, and pedestrian amenities
In addition to technological innovations, future concepts of “smart” and “compact” growth and
transportation planning will emerge. Integrated technologies will support this ideal vision of the
future. However, the integration of ideas and lifestyle rethinking will be the main drivers of this
visionary future. Radical changes in land-use patterns will be observed. Commuters will live closer
to job locations and related activities. With the full deployment of telecommuting capabilities,
suburban areas will see more “business centers” where workers that live nearby will go to work,
regardless of their employer location. Government may also support people living within a certain
distance of their place of employment. That will cause the miles traveled between jobs and housing
to be reduced dramatically, having a positive impact on travel-time reliability.
SUMMARY
Travel-time reliability will improve through the collection and use of more and better information,
together with agency integration and adoption of shared goals. The application of that information
can be used to balance and manage demand and transportation system (multi-modal) capacity
more effectively. That means using information to actively expand capacity in those places where
its value exceeds the cost of that expansion. At the same time, information can be provided to
travelers so that they can make informed choices about the best travel option for them, given their
own values of time and reliability.
