Book excerpt: The 2000 HCM (Highway Capacity Manual) suggests the capacity of two-lane, two-way highways to be 3,400 pcph for both directions and 1,700 pcph for one direction. In fact, higher traffic volumes have been observed in previous studies. Also, a single capacity value cannot reflect the variety of traffic, geometric, and driver conditions that may exist on two-lane, two-way highways. In addition, observation of capacity is difficult, so a new simulation model is developed in this study. Capacity of two-lane, two-way highways is estimated using a microscopic simulation model, which is developed with MATLAB 6.5. Due to the absence of capacity data, the newly developed simulator, TWOSIM (Two-lane, two-way highway SIMulator) is compared to existing analytical tools such as TWOPAS and 2000 HCM method for verification of its performance. Using TWOSIM, the capacity (i.e., 100 percent no-passing zone, all passenger cars and commuters, level tangent section, 12' lane width, 6' shoulder width) for one direction is estimated to be 2,100 pcph at 60 and 70 mph average free flow speeds, 2,000 pcph at 50 mph average free flow speed, and 1,850 pcph at 40 mph average free flow speed. These estimated capacities are higher than the 2000 HCM's estimated capacity for one direction. The presence of passing zones was not found to increase capacity. Additional capacity values are estimated to account for the presence of a driveway, a horizontal curve, a grade, and various percentages of trucks in the traffic stream. These treatments were found to reduce capacity (5~38 percent reduction in capacity). Based on the results, recommendations are provided regarding changes in the 2000 HCM, as well as in the model calibration and algorithm improvement of TWOSIM.

Available in PDF, EPUB and Kindle. Book excerpt: This project presents research on estimating traffic performance on two-lane, twoway highways. The main research objective is to examine two new approaches / methodologies in estimating the Percent-Time-Spent-Following (PTSF), a major indicator of performance on two-lane highways. The first new approach, named the weighted-average approach, is based on the weighted average of speeds for various vehicle types within the traffic stream. The second new approach, named the probabilistic approach, is concerned with using probabilities in estimating the PTSF. The need for this investigation has arisen from the concern that the current analytical procedures, namely the Highway Capacity Manual (HCM) 2000, provide erroneous results as suggested by previous research. The project reviews recent literature on the HCM procedures and evaluates their effectiveness using both theoretical and empirical analyses. Furthermore, the two new approaches were evaluated using empirical data from three study sites located throughout Montana's two-lane, two-way highway system.

This book was released on 2015 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared to previous versions of the manual, the Highway Capacity Manual 2010 has provided more comprehensive capacity models for single and multilane roundabouts. The Highway Capacity Manual 2010 multilane roundabout capacity models are limited to two-by-two lanes, that is, two entry lanes and two circulating lanes. These capacity models are not valid for the three-by-three-lane roundabouts (three entry lanes and three circulating lanes) due to different traffic flow characteristics and features. This limitation of the Highway Capacity Manual 2010 model is also clearly mentioned in the manual. In this research, capacity models and curves were developed for three-by-three-lane roundabouts. More than 168 hours of video recordings were done on 12 three-by-three-lane roundabouts. The extracted data from the video recordings was used to understand the traffic operations and to develop the capacity models. It was found that lane utilization of the outermost circulating lane was low, and drivers preferred to use the middle entry lane for through movements as compared to the other two lanes. Based on the performance and usefulness, exponential regression models were selected for capacity estimation. The capacity curves were developed for the entry approach and for each entry lane of the three-by-three-lane roundabout. These models were used to estimate the follow-up headway and critical gap. The output of the proposed models showed that the entry volume decreases with the increase of the circulating flow at the three-by-three-lane roundabouts. The proposed models were also validated using a microscopic traffic-simulation model. A close association was found between outputs from both models. Transportation engineers can use the vii capacity models and curves presented in this research to perform the three-by-three-lane roundabout capacity analysis. Keywords: Three-by-three-lane roundabout, multilane roundabout, VisSim, capacity models, capacity curves, conflict areas.
