That seemed good for checking the turning movements on an existing road. I really liked the feature where you select a polyline as the boundary (like a curb), then AutoTurn would automatically follow the edge, but not allow any part of the vehicle to cross the line. The process to put the model together (choosing the course) was different, but I think that the end results are about the same.ĪutoTurn had some really neat features, and it seemed like the vehicles were more polished as far as detailing of the actual vehicle. They both seemed like great products, and did essentially the same thing. I tried AutoTurn and Autotrack before we purchased AutoTrack. > But I don't know any other program so I don't know which one is better. > And their program is 99% exact to reality!

InĪddition, I far preferred its tools for editing a vehicle path such asįor driving a semitrailer around a roundabout and getting it wrong on Or Autoturn to demonstrate something far more akin to real life than youīecause I used Autotrack first, I found it better than Autoturn. Steering geometry to manufacturer's specification?īlood alcohol content of measuring techinician?īeing realistic though you will get good results from either Autotrack If your client just wants to make sure that the occasional SU truck can manuever, then the lisp routine would probably work fine, but if he is wanting to allow for constant use vehicles, then being conservative will allow the vehicle to manuever without slowing down too much and without too much risk of damaging something.ĭid they mention what sort of surface the vehicle was driving on? It models the actual car movements, including speed of making the turn, not just whether it "can" be done. I feel that this gives a more accurate (and more conservative) result. But it may be perfect for what you want!Īlso, AutoTrack (and AutoTurn I assume) has vehicle dependent turning rates, so you can set the speed (like 5 MPH) and the turning rate "lock to lock time" (time it takes to turn the steering wheel).
VEHICLES AUTOTURN HOW TO
That made it much more difficult to use, because you have to define the vehicle that you are using without very much information on HOW to define the vehicle. I was not confident that this lisp is giving accurate results, particularly because it depends on ME correctly imputing the vehicle dimensions and features. I tried it out before buying AutoTrack, but was wanting something easier and more "sure". It is a lisp routine which models turning. If what you mean by simple is "inexpensive", then turn.lsp should work. I also like that it has a "follow the line" mode, where you draw a polyline for the vehicle to follow. It has a lot of available vehicles including California standard vehicles, AASHTO vehicles, and some smaller "presentation" vehicles like a Mini and a Ford Focus. It was slightly more expensive than AutoTurn for a single license, but much less expensive for a network license. With the dongle, we can have it installed on multiple machines, and just use the dongle where needed. We went with AutoTrack because I liked it a little better, and it has the option of using a USB dongle for the license. I am not sure if it is simpler that AutoTurn (which I thought was pretty easy to use too, but different).
