Sell BRT lane space to pay for expansion

I read a lot of transit agency reports, about funding to acquire lane space for BRT. Ultimately they get stuck on waiting for funds from federal government. These agencies have value outside of central government, their ability to repurpose existing lane, shoulder and meridian space. Use that valuable power to sell BRT space, before raising debt. Presell to private passenger bus companies, then to light weight cargo movers.

Mixing HOT lans and high speed protected lanes

Easy to do if the protected lane(s) are center and HOT lanes just outside.  Then we can create merge zones.

Important along the Interstate 15 speedway project.  We want to purchase virtual exchange services from the existing HOT and regular lanes.  Vehicles from the protected speedway, slowed down to human driver rules, should lease existing exchange usage, rather than build anew.

Traffic bandwidth can be bought, by the day, the rate, or many other terms.  Traffic light priority and extension has a price.  Sell yield rights.  All of this makes is much easier to fund the DOT services and get a continuous high speed bus path.  Start pre-selling traffic bandwidth along the I-15 corridor, today, promise much higher speeds, up to 120; much longer articulated vehicles, and point to point logistics by way of virtual lanes.

Compatible transponders
Standard across the industry, so vehicles in the HOT lanes get beepers from the fast movers in protected lanes.

DOT fact finding on congestion pricing

Grush Hour reports on a fact finding tour (taxpayer funded junket) by leading DOT officials. Among the issues was this:
Something new that I learned from the Webinar: “Singapore estimates that the gas tax would need to be raised by $3 to achieve the same traffic reduction results as a $1 increase in their electronic road pricing system due to transparency of the charge.”
The transparency means more precision. Drivers can pick among more than one congestion option, each additional option inflates the production system generating more matches to the travel requirements of the drivers. The transaction costs of delivering more basic congestion options from a larger single option is minimal, subdivision is lanes over periods is simply software.

The new Congestion Pricing Technology

This first generation of automated traffic is only the dashboard device with communications , GPS and drivwe display. It is used to signal changes into the congestion priced lane and to display a pricing bar. These devices are about to be released into the retail sector. They can listen and talk, mainly telling each other and base stations who, what and where they are. The driver display is simple, but it can display the locations of cars around.

Base stations broadcast intersection light changes, re-broadcast vehicle locations. Base stations send back pricing information, and confirm charges.

There will be an after market to connect dashboard devices to collect turn signal and cruise control data from the car, and send cruise control commands back. Hence, we will see driver controlled road trains almost from the start.

There will be a confluence of forces, metropolitan governments going broke and drivers wanting to cut through traffic congestion.
