Abstract Street design plays an important role in controlling vehicular speed. This has a direct impact on enhancing the safety of road users and quality environment for residents living adjacent to streets. The increasing accidents every day is worrisome. other adversely affected when drivers travel at high speeds. Speeding also cause noise air pollution, which may negatively community livabil...

block stops. There are few streets over which street cars are operated that are wide enough for the street-car lane, a lane for moving vehicles, and a space for parking. The usual condition is that the moving vehicles must use the car-track space, since the other lane is used for parked vehicles. Just one parked vehicle per city block will keep the outside lane from being used by moving vehicle...

Many natural and man-made lineaments form networks that can be analysed through entropy and energy considerations. Here we report the results of a detailed study of the variations in trends and lengths of 1554 named streets and 6004 street segments, forming a part of the evolving street network of the city of Dundee in East Scotland. Based on changes in the scaling exponents (ranging from 0.24 ...

STUDY OBJECTIVE To examine how child pedestrian exposure to risk, as measured by the mean number of streets crossed, varies according to indices of material disadvantage and ethnic group. DESIGN A questionnaire on pedestrian exposure to risk was distributed to children for completion by parents and return to school. Children from 40 schools were selected using a probability cluster design. ...

Processive molecular motors which drive the traffic of organelles in cells move in a directed way along cytoskeletal filaments. On large time scales, they perform motor walks, i.e., peculiar random walks which arise from the repeated unbinding from and rebinding to filaments. Unbound motors perform Brownian motion in the surrounding fluid. In addition, the traffic of molecular motors exhibits m...

World cities need more green areas to promote social, economic, and environmental well-being; the problem, however, is that space available for infrastructure (GI) within built environment limited. Finding empty, free, or underutilized spaces be repurposed GI has been a challenge. Streets are public, numerous, evenly distributed, being desirable place fulfill this requirement. However, they als...

We consider the problem of a robot inside an unknown polygon that has to nd a path from a starting point s to a target point t. We assume that it is equipped with an on-board vision system through which it can get the visibility map of its surroundings. Furthermore, we assume that the robot is contained in a simple polygon that belongs to the class of generalized streets. We consider three prob...

We define an elliptic equation for Hermitian metrics which is related to the Einstein condition. Solutions to this equation are closely related to Kähler-Einstein metrics, and are automatically Kähler-Einstein when a certain non-positive condition is satisfied by c1(M). Given this, a natural flow equation arises taking Hermitian metrics to Kähler metrics. We prove short time existence and regul...

We present a four-stage meta-heuristic for routing vehicles in an urban environment, with the goal of traversing every street. While the theoretical aspects of street traversal are well-studied, our algorithm is designed to accommodate several obstacles to practical street traversal that are known to be NP-hard, such as turning penalties, the usage of multiple vehicles, and the presence of onew...

Mean streets represent those connected subsets of a spatial network whose attribute values are significantly higher than expected. Discovering and quantifyingmean streets is an important problem with many applications such as detecting high-crime-density streets and high crash roads (or areas) for public safety, detecting urban cancer disease clusters for public health, detecting human activity...
