The capacity of signalized intersections can be determined with the combination of signal timing and saturation flow. The performance on signalized intersections also depends on signal timing, e.g., stopped delay can be estimated with the combination of green time, cycle length and the other parameters. A method or a parameter for performance evaluation on signalized intersections should be able to evaluate the contribution of various traffic control strategies on intersection performance. Therefore, the problem of evaluation by traffic dependent control strategy was addressed in this paper. As example, this paper presents the result by traffic actuated control. Further research is to be expected in the future with respect to the conclusion of this paper.","PeriodicalId":123979,"journal":{"name":"Highway Capacity and Level of Service","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115607822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Capacity of weaving sections, however, is affected by many variables such as four directions of flows and variety of lane configurations, and it is difficult to estimate capacity of weaving sections through statistical analysis based on observed capacity data for various geometries and flow conditions. It is therefore considered that the capacity value may be reproduced by the aggregation of individual driver behaviors. Using vehicle trajectory data obtained from observations on several weaving sections on urban expressways in the Tokyo area, such microscopic variables as spacings and relative speeds of weaving vehicles were analyzed. Based on these analyses, a simulation model which is intended to estimate weaving capacity was developed. Such maneuvers of weaving vehicles as lane changing and acceptable gap searching which affect capacity were particularly precisely modeled. The model was validated for two congested weaving sections of the Tokyo Metropolitan Expressway. Simulated values of capacities were found to fit well with the observed ones.","PeriodicalId":123979,"journal":{"name":"Highway Capacity and Level of Service","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125111137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The speed-flow relationship was found to be linear. For platoon percentage and mean platoon length as a function of traffic flow loglinear relationships were used. For the mean platoon length as a function of platoon percentage a hyperbolic relationship was used. The percentage of vehicles driven with time headways less than 5 seconds was used as an approximation of the percent time delay (PTD) of the 1985 HCM. The measured flow levels on high-class roads corresponding to a certain PTD-value were lower than the level of service calculation procedure of the HCM would suggest. The probable causes of the differences are the difference of the HCM adjustment factors and those needed for Finnish road and traffic conditions and different speed-flow curves (Finland versus USA).","PeriodicalId":123979,"journal":{"name":"Highway Capacity and Level of Service","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116173453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
