Abstract
Transport Model is always needed and important for developing Transportation System Master Plan. Trip Distribution is one of the important parts of Transport Model, which is a result mathematical operation of trip generation and deterrence function. Trip Length Distribution Pattern is the foundation of Deterrence Function. The trip length distribution pattern can change due to the various trip length interval used. Analog to this, the Deterrence Function can also change. The research result indicate that the distribution pattern change significantly on trip length interval 1 to 3 km. For trip length interval of 4 to 8 km, the trip length distribution indicate the general characteristic of trip length distribution, i.e. the number of trips is high in short distance and getting down in the longer trip distance. The trip interval of 7 km gives the most accepted Tanner Deterrence Function .

Summary
Amaster plan of transportation system, either urban, regency, provincial or national need to be reviewed and re-developed for each 5 year. The number of trip can be significantly small in very short distance, follow by a peak value and gradually less and less [1], [7]–[9] These general characteristics, in European custom transport modeling, normally are modeled by three mathematical formulas: negative power model, negative exponential model and Tanner model. Gravity Model with Deterrence Function developed based on Trip Length Distribution Pattern with Trip Length Interval = 1 still can be found [10]. This generates a big question: Is using TLD Pattern with Trip Length Interval = 1 is appropriate enough?. The distances between the office to their houses were taken as working trip length with a certain distribution pattern
