Driver behavior plays an important role in modeling vehicle dynamics in a traffic simulation environment. To study one element of the general driver behavior, that of car following, an advanced instrumented vehicle has been applied in dynamic data collection in real traffic flow on Swedish roads. This paper briefly introduces our car following data(More)
—This paper first reports a data acquisition method that the authors used in a project on modeling driver behavior for microscopic traffic simulations. An advanced instrumented vehicle was employed to collect driver-behavior data, mainly car-following and lane-changing patterns, on Swedish roads. To eliminate the measurement noise in acquired car-following(More)
This paper describes results from a case study to calibrate and evaluate of the microscopic traffic simulation model MITSIMLab, to a mixed urban-freeway network in the Brunnsviken area in the north of Stockholm under congested traffic conditions. In the absence of detailed data, only aggregate data (i.e. speed and flow measurements at sensor locations) was(More)

Podcars or Personal Rapid Transit (PRT) has been discussed and analyzed in Sweden since the mid-1960's. Interests in PRT has gone up and down over time. Since the mid-1990's, however, the efforts of promoting PRT in Sweden have become more serious and frequent. Many pre-feasibility and a few feasibility studies were undertaken by researchers, consultants(More)
The name Personal Rapid Transit (PRT) indicates that passengers are served on an individual basis. It is an important quality of PRT that passengers do not have to wait for vehicles to be filled up. They travel alone or in company of their own choice. PRT vehicles like taxis are designed for small parties, typically for 3-5 passengers. In this paper we will(More)
