1. 6. Analysis of side friction impacts on urban roads : Case study Dar-es-Salaam

   Författare :Masatu L. M. Chiguma; Karl-Lennart Bång; Christer Hydén; KTH; []
   Nyckelord :Side friction factors; urban road links; speed-flow relationships; macroscopic method; microscopic method; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

   Sammanfattning : Side friction factors are defined as all those actions related to the activities taking place by the sides of the road and sometimes within the road, which interfere with the traffic flow on the travelled way. They include but not limited to pedestrians, bicycles, non-motorised vehicles, parked and stopping vehicles. LÄS MER

3. 7. Driver Modeling based on computational intelligence approaches : exploaration and Modeling driver-following data collected by an instrumented vehicle

   Författare :Xiaoliang Ma; Karl-Lennart Bång; Mark Dougherty; KTH; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : This thesis is concerned with modeling of driver behavior based on data collected from real traffic using an advanced instrumented vehicle. In particular, the focus is on driver-following behavior (often called car-following in transport science) for microscopic simulation of road traffic systems. LÄS MER

4. 8. Framework for Estimating Congestion performance measures : from data collection to reliability analysis: case study of Stockholm

   Författare :Carlos A. Morán Toledo; Karl-Lennart Bång; Muriel Beser Hugosson; KTH; []
   Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

   Sammanfattning : For operational and planning purposes it is important to observe and predict the traffic performance of congested urban road links and networks. Congestion can be defined as traffic conditions caused by a downstream bottleneck or excess in travel time from what is incurred during light or free-flow travel conditions. LÄS MER

5. 9. Advancing Traffic Safety : An evaluation of speed limits, vehicle-bicycle interactions, and I2V systems

   Författare :Ary Pezo Silvano; Haris Koutsopoulos; Haneen Farah; Karl-Lennart Bång; Alfonso Montella; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic safety; urban roads; posted speed limits; road characteristics; free-flow speed; time headway; vehicle-bicycle interactions; logit model; yielding probability; cooperative systems and warning messages.; Transportvetenskap; Transport Science;

   Sammanfattning : Since the introduction of motor vehicles, the number of fatalities and accidents has been a concern for society.The number of fatalities on roads is amongst the most common causes of mortality worldwide (WHO, 2015).Even in industrialized countries the number of fatalities remains unacceptable.

7. 10. Impacts of Speed Limits and Information Systems on Speed Choice from a Safety Perspective

   Författare :Ary P. Silvano; Haris N. Koutsopoulos; Karl-Lennart Bång; Haneen Farah; Johan Olstam; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speed choice; urban; roads; speed limits; road characteristics; traffic safety; cooperative systems and warning messages;

   Sammanfattning : Driving a vehicle is considered a demanding task in a complex dynamic environment. For instance, driving a vehicle on urban roads, where motorized vehicles meet vulnerable road users (VRUs) creates a multifaceted environment with difficult trade-offs and interactions. LÄS MER
