What is the TriTrack?

The TriTrack is a dual-mode electric car. Dual-mode means it can drive both on the ground and on an elevated guideway. It is a personal car that you purchase and keep in your own garage.

How many people does it hold?

A TriTrack car will hold up to four 180 pound passengers, or the weight equivalent. The interior has two comfortable bench seats.

How fast does it go?

On the ground, the TriTrack is governed down to 25 mph, legally classifying it as a Neighborhood Vehicle. On the guideway, it will speed up to 180 mph. By moving quickly, you can get across town and do what you need to do in a reasonable amount of time.

Isn't 180 mph dangerous?

In a standard car, driving on the ground, yes, 180 mph is very dangerous. However, while on the guideway, the TriTrack is computer controlled. Computers ensure that everyone on the track is moving at the same speed, and if one car fails, all other cars will instantly react to avoid a collision in concert. The car is held onto the track in all directions and there is no way for it to come off. The safety record of monorails is incredible compared to that of highways, and there will actually be many fewer fatalities with the TriTrack in place.

A commercial airliner goes 360 mph, and nobody complains about the speed.

Why does it have to be that fast?

Some people are nervous that higher speeds are too dangerous, but that is mainly only true on the ground. The real reason for the speed is the increased capacity of the system at the same cost. As cities grow and more and more people need to get across town, the transportation infrastructure needs to grow at the same time. Each guideway has the capability of moving 9,000 people per hour, equivalent to 3 highway lanes.

What about merging? Doesn't that complicate things too much?

The only merging that the TriTrack does is on the ground. The car can only get on the guideway at the beginning and only get off at the end, and there are always multiple lanes of guideway for each line on the grid. Each lane is a different length, and the driver gets on the correct length guideway for where they want to go.

How do I know which guideway to drive onto?

When you get in your car you have two options:
-If you know where you want to go, you get in the car and just go.
-If you aren't sure which guideway to get on, or if you want to avoid traffic, there is an onboard computer with GPS mapping software. You type in where you want to go, and the computer directs you to the optimal route.

How do you turn?

At 180 mph, you would need a 3 mile turning radius to make a comfortable turn because of the centrifugal force. In a TriTrack, you come down off the guideway, then get on a new guideway going the other direction. The guideways are at two different heights. One direction (i.e. North-South) will be at 17ft, and the other (East-West) will be 23ft. This eliminates intersections and lowers your risk of collisions.

What if someone doesn't drive onto the guideway just right? Is there any room for error?

There is a dedicated Merge Zone on the ground for transitioning from existing streets to the guideway. Once the driver crosses into the border of this merge zone, computer control takes over and accurately steers and speeds you to the guideway.

What powers the TriTrack?

There are actually 4 different Power Modes:

-On the ground, the car is powered by a battery mule. The batteries would likely be lead acid, similar to those in golf carts because they are inexpensive. The mule could alternately be filled with anything that fits in the space, including hydrogen fuel cells.
-When the TriTrack gets on the guideway, the battery mule is left behind and the guideway occupies the space where it was. To speed the car up and increase its elevation, there is a linear motor built into the track that interacts with permanent magnets in the car body. This 300 hp launch motor is powered directly by the power grid.
-While on the guideway, a smaller battery in the car maintains its speed. Because the car is so aerodynamic, it only requires 60-90 hp to stay at 180 mph.
-When the TriTrack reaches the end of the guideway and comes down, there is a linear generator to recapture some (96%) of the car's energy and slow it down. This goes directly back into the power grid. At the end of the guideway, a different fully charged battery mule joins with the TriTrack at 40 mph and the car is again ready for surface streets.

What sort of range does the TriTrack have?

Because the car picks up a fully charged battery pack with each hop, the range is virtually limitless. The grid is spaced ½ - 2 miles apart, so the most you would ever have go on the ground would be half the grid spacing. If you wanted to drive a TriTrack to a place that doesn't have a grid installed yet, you can convert it to a hybrid by attaching a trailer.

What if there aren't enough battery mules at the end of the guideway?

-There are several answers to this question:
Batteries take longer to charge than to discharge, so there will be many more mules than there are cars. Consequently, there will always be several mules waiting at the end of each guideway.
-Traffic patterns are fairly regular for any given day of the week, so it will not be hard to predict which areas will need more mules.
-If there is a big event going on, we'll know about it in advance and ensure that there are enough mules waiting.

How much does it cost to buy/drive? Is it expensive?

It costs about half as much as a traditional car to drive. According to AAA, the average cost of driving a new car in 2003, which includes depreciation of the car, financing, maintenance, gas, etc, is $.56/mile plus any tolls for driving on toll roads. The equivalent cost of driving a TriTrack is $.31/mile which includes a $.035 per mile surcharge for building the guideways. In 5 years, this $.035 would pay for the full cost of installing a grid in Austin.
Our calculators can help you get a better understanding of these numbers.

How will you get the land for the guideway grid?

The guideways are elevated, which means they can be put in place on top of existing right of way that is underutilized. The piers that support the guideway each take up only 1 sq ft of ground space.

Who is going to pay for/build the infrastructure?

-The city and state who currently build roads and highways would build the guideways. The guideway is fast and inexpensive to construct. With the TriTracker, guideway can be extruded on site at a speed of 3 mph, and the cost is $150,000/mile. For comparison, standard highways cost upwards of 10 times that amount.
-The power company would own the battery mules. With a huge infrastructure of batteries, the power company could flatten their daily demand curve, resulting in less idling time at the power plant, and thus a price reduction in the cost of all your electricity.
-The cars are patent pending, and the plans for building one would be licensed out to big automotive companies like Ford, GM and Daimler-Chrysler. You would buy your own car, just like you do now, but it would cost about half as much, $10,000 on average.

How long has the TriTrack been around?

The car has been in the development phase since the first oil embargo. We really started focusing on it in the past 5 years, and we've been promoting it for the past 2 years.

Are there any cars in production yet?

We have built a full body shell that has been tested for strength, weight and corrosion resistance, and we have a 1/8th scale model for display. We expect to have a functioning prototype within a year from receiving funding, and cars for sale to the public within 4-5 years.

How much funding do we need?

In order to build a full scale functioning prototype car and 3000ft test track, we will need $1 million. We are currently looking for personal investors and/or corporate sponsors who can help with some or all of that amount.

What keeps the TriTrack from falling off the Guideway?

6 wheels grab on all 3 sides of the guideway, both in the front and back of the car. In addition, the body shell of the car wraps around the guideway so that if the wheels break off, the car will still not be able to come off the guideway.
