   Författare :Albania Nissan; Haris N. Koutsopoulos; Tomer Toledo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorway Control System; Mainline Control; Variable Speed Limits; Driver Behavior; Capacity; Intelligent Transport Systems; microsimulation model; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Mechanical energy engineering; Mekanisk energiteknik; Mechanical energy engineering; Mekanisk energiteknik;

   Sammanfattning : Variable Speed Limits (VSL) are often used to improve traffic conditions on congested motorways. VSL can be implemented as mandatory or advisory. The objective of the thesis isto study in detail the effectiveness of VSL. The focus is on both, design parameters and conditions under which VSL are most effective. LÄS MER

3. 2. 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
