A comparison site (or group of sites) is used in order to control for factors other than the road modification.
Conversely, the set D (Table 3), including alignment and road standard modifications, can be potentially assessed by all the methods considered, since they include geometric variables.
As the model expands into regions that are less densely populated, and with more difficult road conditions, modifications to the model are expected to enable delivery optimization.
From Thurston's perspective, more people need to be sequenced and more research needs to take place before you can go down the road of modification.
Some deep and large gullies, due to road induced modification of water drainage at the origin of channelization in the steep lower-slope, were also observed in this area.
Our results suggest that interventions to reduce deaths as a result of MVCs should focus on both driver-related and road-related modifications.
Most previous research on edge effects had focused on abiotic factors, such as changes in light, humidity, or seed arrival patterns in newly formed "edges" where adjacent forest has been cleared for agriculture, roads or other modifications.
Transportation officials in Idaho and Montana say that their roads — with some modifications made and paid for by the companies, including additional pullouts along the route and raised or buried power lines — could handle the shipments.
In this context, it is important to understand that for a vehicle to qualify as fully autonomous, it should be able to navigate itself in real traffic within roads which have not been specifically adapted for its use, but this does not mean that there will not be broader modifications to road infrastructure to accommodate the AVs.
However, the effectiveness of polymer modification in improving road performance depends on a chemical-structural modification in the binder's composition to be effective and durable.
