In traffic demand forecasting process, subdividing zones is needed to know trip pattern among smaller zones than existing O-D zone system. Trips among subdivided zones are generally estimated because it is difficult to obtain the real data. Generally, Production of subdivided zones is estimated by population ratio of subdivided zones with respect to existing zone. But it has a weakness which it can not explain properly characteristics of each linked trip (Especially in case of non home-based trip). Therefore new methodology to estimate production of subdivided zones for each linked trip is proposed in this paper. The methodology uses more socio-economic indexes and equations of regression for production. To evaluate the methodology, real data of Haenam County in Korea is applied. The error of estimated production by the methodology will be smaller than that by existing methodology. After all, more accurate traffic demand forecasting will be possible by the methodology.
