[edit] Test Data Instances

Many of these are links to sites with general optimization test sets, not just transportation problem test sets.

VRPLib Vehicle Routing test problems
TSPLib Traveling Salesman test problems
MIPLib Last updated 2003?
Coral Instances from Lehighs' OR group. Site also contains set partitioning instances and open source optimization software
LINLib A collection of instances, many of them in GAMS and with some overlap with other links above
Argonne National Labs Have to provide email address to download, models in AMPL or GAMS. Haven't looked closely, but these may primarily be nonlinear models.
Arnold Neumaiers' Global Optimization site Many links to test sets for non-linear, combinatorial and various other optimization models.
QAPLib Quadratic Assignment Problem Instance Library
SNDLib Survivable Network Design Problem Instance Library
Hans Mittleman - ASU Links to various sites. Scroll down to see a link to a set of Fixed Charge Transportation instances
ORLib OR Library maintained by John Beasley (Large variety of OR problems)
Huseyin Topaloglu - Cornell University Stochastic programming test problems
Transportation Network Test Problems focusing mainly on traffic assignments.
Barrett Thomas - University of Iowa Test sets for the TSPTW and the Probabilistic Traveling Salesman Problem with Deadlines (PTSPD)
The National Highway Planning Network The National Highway Planning Network (NHPN) consists of interstates, principal arterials, and rural minor arterials.
