    As a consequence of worsening traffic congestion in metropolitan areas, the shifting of travel between transportation modes is becoming a pressing need. Urban public transit systems are often seen as effective alternative modes to mitigate traffic congestion, so it is expected that such systems will see increasing ridership. Improving the quality of transit service and increasing the operational efficiency of transit systems are essential to attracting more passengers to public transit. In reality, the modal choice decisions are more sensitive to the amount of time that transit passengers spend in transferring between modes than the time they spend on board. This research considers the problem of developing synchronized timetable for anbessa bus and addis ababa light rail transit for mercato station when waiting time limit exist at each transfer stops, for passengers making connections. The objective of this research is to have maximum number of simultaneous arrivals. Previous studies defined simultaneous arrival as an arrival buses and train of different routes at a transfer point such that the time between these arrivals did not exceed the passengers waiting time range associated with transfer stop. A heuristic model is developed and applied for the case merkato terminal to evaluate the outcome. The total number of synchronization obtained by the model and passenger waiting time was compared for different headways of buses. Results show that as the headway of anbessa bus is reduced the number of simultaneous arrivals increases and waiting time of passengers reduced.
