In this work, a new class of Runge-Kutta (RK) type colocation methods for numerical integration of ordinary differential equations (ODE) is presented. Compared to classical RK methods, the derivation of methods is based on the weighted integral form of ODE. The approach makes it possible to increase the accuracy of established RK-type collocation methods while retaining the same number of methodʼs stages (i.e., the number of methodʼs coefficients). The behaviour of methods is demonstrated on an analytical (test) and numerical example.
