I I.ABSTRACT This paper is a report on a simulation study of FM 1709. The study considered the impact that increasing traffic flow rates will have on congestion on this road and what changes or improvements might occur if the road is widened. A model of the road was developed which represented the stretch of FM 1709 between Pate-Orr Road in the east and Highway 114 in the west and contained five traffic signals. SIMAN was used for developing and running the simulation. A brief discussion of SIMAN is included in the report. The operation of the model is described in detail and a flow chart is provided. Six treatments that were obtained by combining three levels of traffic flow with two model configurations were run for this study. The results that were obtained are disappointing in that problems with the program both in the coding and in the capacity that was available precluded acquiring meaningful average travel time data for comparison of the various treatments. However, time average data for the number of vehicles in the eastbound (main flow) queues are clearly indicative of worsening congestion in the one-lane model with increasing traffic levels, and it can be seen that the two-lane model is relatively free from these effects. Recommendations are then made concerning the reed for widening FM 1709. Finally, there is a discussion of possible ways to improve this study so that better results can be achieved.A Simulation Study of FM 1709 by Catherine Dottle This study of FM 1709 concerns the impact of traffic increases due to population growth in the area. FM 1709 is a commuter route from Keller to Grapevine and thence to Dallas. Much of Southiake is also served by this route. I must travel this road, which is one lane each way, every day. Rumors that plans to widen the road are in the works have been common since I moved to the area nearly ten years ago, but nothing has been done along those lines even though traffic congestion has worsened significantly. I decided to do a simulation study to try to determine what effects the projected growth in the area could be expected to have on the congestion on this road. I also wanted to see what changes in these effects would result from simply widening the road by an additional lane each way. As can be seen on the maps on pages 2 and 3, FM 1709 is in the northern part of Tarrant County and links Keller and parts of Southlake with Highway 114. The portion I modeled for this study starts at Pate-Orr Road at the east side of the more built-up part of Keller, where one leaves in-town traffic when going east. Then the portion being considered continues east through five intersections having traffic lights, as well as several more minor intersections, to Highway 114, where FM 1709 ends.-.
