The research aimed to know the amount of estimation trip distribution models using the gravity method. In addition, to know the validation levelby comparing traffic flow resulted from the model and observation. This research was conducted in Surakarta as areas of studdy dividing the areainto 65 zone, 51 internal zone and 14 external zone. The road network that is analyzed is the arterial roads and collector roads. The methodwas used is gravity model as production and attraction constrained as estimation model MAT 2013 with EMME/3 software. On this modelthere are parameters ?that function as determinants of the magnitude of the spread of values that occur in each zone. Calibration method for obtainingparameters ?that are later used in the calculation of the estimated results of the MAT (obstacle function with Tanner) is the Newton-Raphson method of calibration. The calibration is done by a process of repetition until the convergence parameter value reaches the limit usingMatlab software application assistance. The Traffic volume values obtained by imposing a new matrix and incorporate current observations (trafficcount) to the road network by the method of loading User Equilibrium, is loading method which has the assumption that the total amount of thetrip will be entirely charged to all segments of the road network. Test Validation using the coefficient of Determination (R2). From the results ofcalculations with the help of Matlab is obtained by 0,0006. From the results of calculations with the help of EMME / 3, obtained by the totalnumber of movements in Surakarta is 35923.9 smp / hour. The level of validation (R2) is obtained by 0.77. Validation in the category of high,has 77% similarity with the original conditions on roads.

Origin Destination Matrix is a two-dimensional matrix that contains information about the amount of movements among locations (zones) withina certain area. Origin Destination Matrix Estimation is used to determine the distribution of the trip in order to analyze the performance of theroad network in Surakarta. The study aims to determine the distribution of the movements of the traffic flow in the city of Surakarta representedwith OD Matrix 2025.OD Matrix year 2013 Estimation is obtained from process by prior matrix data, calibrated using the generation andthe pull model by regression analysis method to produce the amount of generation and attraction in 2025. The data used to calibrate the data issocio-economic in that year. For generation, the most significant variable is the number of the population, while the amount of land areasignificantly affects the traction effort. After obtaining a number of generation and attraction for 2025, subsequently estimated using a model withconstraints generation Gravity and pull (DCGR). Parameter ? = -0,15127 use values obtained from research Isnaini (2013).The study wasconducted by dividing the study area into 65 zones with zone 51 internal and 14 external zones processed using the program EMME/3 andSPSS 17. Distribution of movement Surakarta years presented in the form of a matrix and simplified into the form of a bar graph. Totalmovement that occurs is equal to 55.074.29 pcu / hour , movement between internal-external zone seen in largest graphs is 28.27%, the nextorder of the internal-external movement of 25.21% and the internal-internal of 23.98%. For external-external zones were relatively smallmovement that is 14.69%. The smallest movement occurs in intrazona is 7.86%..

Transportation problems such as congestion, noise and air pollution, accidents, delay and other problems happen because the bigger movement tofulfill life necessities which is more complex. It can be solved by using good transportation planning. MAT is a two-dimensional matrix containsinformation about the amount of movements inter location (zones) within a certain area. MAT can provide a detail indication of the movementsneed, so MAT plays important role in the study of transportation planning and management. This research was conducted in Surakarta by dividingthe study area into 65 zones with 51 internal zones and 14 external zones. In analyzing of road network, it includes arterial roads and collectorroads. The aims of this research are to determine the magnitude of Origin Destination Matrix estimation of the data traffic using applicationEMME / 3 at Surakarta in the year of 2013, and also the research is intended to know the level of validation of traffic flow using the result ofmodeling of traffic flow observation in the field. In this research to estimate the MAT in the plan, it use the limitation Gravity Model productionand attraction movement. This research also uses Matlab software application to get the value of the parameter ?with exponential-negative barrierfunction. The traffic volume value was obtained by imposing new matrix and incorporating current observation (traffic count) in the road network.Test validation using determination coefficient (R2 ). The value of parameter ?by using application software Matlab is -0,00042. The result of thecalculation by using EMME/3 shows the total number of estimation of movement Surakarta in the year of 2013 is 37298,98 smp/jam withlevel of validation (R2 ) is 0,78. This case shows the value (R2 ) of this study fall into the category of high validation, has 78% similarity to theoriginal condition in Surakarta city streets.
