Analysis of a cooperative variable speed limit system using microscopic traffic simulation

The Driver Behaviour and Impact of Speed on Road Safety on the Motorways in Croatia

“…The phenomenon of occurrence of bottlenecks on the motorways and blocking traffic was considered in the work of Mendes et al (2014) and Chen et al (2015) [20,21]. Recent works (2015) based on the research of movement of vehicles on the motorways were made by Grumert [22], Seo [23], Chang [24], Montella [25], Jamshidnejad [26], and the paper in which basic parameters of traffic flow in cities are explored (Horvat et al, 2015. ) [27].…”

Fuel economy testing of autonomous vehicles

“…Through simulations they found that equipping just 5% of a vehicle fleet with this technology could significantly decrease congestion and decrease travel times. Grumert et al (Grumert et al, 2015) investigated setting variable speed limits for cooperative and autonomous vehicles to moderate traffic patterns and decrease emissions. They found significant increases in traffic harmonization and decreases in vehicular emissions when variable speed limits were used and as the portion of cooperative autonomous vehicles increased.…”

Dynamic Speed Harmonization in Connected Urban Street Networks

“…Khondaker and Kattan (2015) showed that VSL strategies reduced the total travel time and fuel consumption by 20% and 16% on freeway facilities, respectively. Grumert et al (2015) considered speed harmonization strategies on a freeway with connected vehicles where the speed limits were assigned to individual vehicles based on their distance to the incident location and the desired speed at that location. The results showed a more harmonized traffic flow and reduced emissions compared to a predetermined and fixed speed limit.…”
