Can Pierce Transit assign a bigger bus on my route so I can always have a seat?

We have a number of smaller buses for use where practicable. However, in our system, buses circulate among routes; after finishing a low-ridership route, a bus may immediately go on to serve one of our more popular routes. As far as expense is concerned, the cost of the fuel saved by using smaller vehicles is offset by our more rugged and reliable (and, therefore, less expensive to maintain) larger vehicles.
