Abstract. Jakarta Cikampek Toll Road is one of the famous toll roads in Indonesia that has been established since 1988. Unfortunately, due to the increasing number of vehicles each year, traffic congestion has begun. This traffic congestion can affect the travel time and travel cost which has been regarded as one of the most fundamental determinants of both short term and long term travel decisions. The objective of this research is to find out factors influencing consumer mode choice decision during severe traffic congestion in the toll road. We design the stated preference questionnaire with four alternative modes, car, travel shuttle, train, and bus using d-efficient design using NGENE software. The attributes for those four alternative modes are travel time, cost, congestion time, waiting time, access egress time and cost. In our questionnaire, the respondents are asked to answer their most likely chosen mode from eight possible attribute combination scenarios.Keywords : Traffic Congestion, Consumer Travel Choice, Jakarta-Cikampek Toll.
