Pictures: Metro screened out of this analysis for now, as they have been determined to be inferior to electric trucks in terms of cost and ability to readily serve the multitude of freight origins and destinations served by trucks using the I-710 corridor.

S.3.2.5 ALTERNATIVE 6C: I-710 WIDENING AND MODERNIZATION PLUS TOLLED FREIGHT CORRIDOR

Alternative 6B also includes the assumption that all trucks using the freight corridor will have an automated control system that will steer, brake, and accelerate the trucks under computer control while traveling on the freight corridor. This will safely allow for trucks to travel in “platoons” (e.g., groups of 6 –8 trucks) and increase the capacity of the freight corridor. Alternative 6C includes all the components of Alternative 6B as described above, but would toll trucks using the freight corridor. Although tolling trucks in the freight corridor could be done under either Alternative 6A or 6B, for analytical purposes, tolling has only been evaluated for Alternative 6B, as this alternative provides for higher freight corridor capacity than Alternative 6A due to the automated guidance feature of Alternative 6B.

The design of the freight corridor will also allow for possible future conversion, or be initially constructed, as feasible (which may require additional environmental analysis and approval), of transport technologies (e.g., Maglev). However, Per Federal statute, unless otherwise excepted, all Interstate highways must be toll-free. However, current exceptions relating to tolling of Interstate highways include Value Pricing Pilot Program; Express Lanes Demonstration 11

LTH (ERS power simulations)

Phase 1 - Done Dynamic simulation of traffic flow Simulation of currents, voltages and component temperatures in the power system along the ERS Uses a short idealized fictive road as an example

Phase 2 - Planned Improved modeling of vehicles Use RV 40 Göteborg – Borås as a real world example of e.g.

traffic patterns and slopes System optimization, battery size vs amount of ERS installed

Vattenfall (Power infrastructure)

Planned activities during Phase 2 of the Slide-in Project:

• Analyses of power requirements, grid connection solutions and cost estimates for a grid infrastructure supporting a “Slide-in Electric Road” between Jönköping and Helsingborg / Malmö

(during Q4 2014)

• Further cost analyses of needed “Traction substation” solutions (at the road side) along the “Slide-in Electric Road”

(during 2014 / 2015)

• Analyses of “partial ERS” solutions on highways in cooperation with the project partners

(during 2015)
