Always remember the traffic moves on the left. So you must be careful. Have a look first or you will go the wrong way. In many English cities, there are big buses with two floors. You can sit on the second floor. From there you can see the city very well. It's very interesting!

Enter Frank Blackmore. In the UK, he introduced the “Priority Rule” which — simply — mandates that traffic entering a circle must give way to traffic already in the circle. Blackmore worked out that this method increases traffic flow by 10%. Although this kind of roundabout became law ...
Whilst I am becoming quite alarmed at the plethora of signage that is sprouting up alongside our highways, many of which have dubious merit to say the least, there are some that are absolutely essential in the cause of road safety. The problem with increased roadside information is that, at ...
Using a traffic simulation model (VISSIM) with an emissions model (MOVES) to predict emissions from vehicles on a limited-access highway The Intergovernmental Panel on Climate Change (IPCC) estimates that baseline global GHG emissions may increase 25-90% from 2000 to 2030, with carbon dioxid.....
Based on speed profile: Enviver Versit+, VT, RoundaboutEM; - Based on vehicle parameters, such as power: CSIRO, CMEM, VT-CPFM, LPGemission; - Combining the above methods. The power-based CMEM model was developed in 2006. Emission processes fall into different categories that correspond to...
B2 is the gap function δ(v, β), in which the preceding vehicle needs to decelerate from speed 𝑣𝑙 vl to the anticipated deceleration speed 𝛽𝑙βl. When the leading car (L) decelerates at time t, the following car (F) takes a lag time τ (the follower’s response time) ...
These inputs could be useful for enabling more precise and dynamic control of the intelligent intersection, crosswalk, or roundabout. However, in this work, the scenario will be restricted to a static scheme with pre-established phase sequences. Figure 2. Overview of the proposed system ...
The scenario with the second lowest energy consumption is Scenario S8C, which assumes the use of a roundabout-type intersection. Vehicles turning left can perform this maneuver more efficiently. The highest energy consumption is calculated for Scenario S5C (all-way stop), as in the other ...
