Hello
I work in a infraestructure office in Chile. When I draw a bus bay I can't use an alignment offset to do it, because the transition type showed in the dialog Box "Offset Alignment Parameters" allows only 4 types of transitions (linear; Curve-line-curve; curve -curve - reverse curve; Curve - reverse curve).
Here, we need to use a Table that contains then incremental widening as function of the incremental lengh of the total transition.
For example:
If i need to draw a bus bay, and the design velocity is 50 km/hr, i will need a 20 m transition lenght. For each meter of the transition lenght, the incremental widening is diferent. If we assume that the bus bay has 3m of width, the transition will be:
1 m length --> 0.0029*3m width
2 m length --> 0.0126*3m width
..
5 m length --> 0.1073*3m width
10 m length --> 0.5*3m width
...
18 m length --> 0.9873 * 3 m width
20 m lenght --> 1* 3 m width.
The cuestion is. Could be possible to customize the transition Type, entering a table parameters, to represent this lenght/width relation? Currently we use polilines as feature lines to target the ensamblies to the curb.
I post a photo of the Chilean norm called REDEVU, in the page that shows this relation.
Thank you in Advance
