optimization is an important methodology for activities in planning and design. the transportation designers are able to introduce better projects when they can save time and cost of travel for project by optimization methods. most of the optimization problems in engineering are more complicated than they can be solved by custom optimization methods. the most common and available methods are he...

OBJECTIVES To compare child pedestrian injury rates on one-way versus two-way streets in Hamilton, and examine whether the characteristics of child pedestrian injuries differ across street types. METHODS The rates of injury per child population, per kilometre, per year were calculated by age, sex and socio-economic status (SES). Child, environment and driver characteristics were investigated ...

Planning scholars have identified economic, safety, and social benefits of converting one-way streets to two-way. Less is known about how conversions could impact vehicular distances traveled—of growing relevance in an era fleet automation, electrification, ride-hailing. We simulate such a conversion San Francisco, California. find that its current street network’s average intra-city trip ~1.7 ...

this study is devoted to the formulation of the network design problem of one-way streets and the application of simulated annealing (sa) algorithm to solve this problem for a large real network. it discusses some points of views on one-way street networks, the objective function used for design, the way in which design constraints may be considered, and the traffic problems concerning one-way ...

In most studies, street networks are considered as undirected graphs while one-way streets and their effect on shortest paths usually ignored. Here, we first study the empirical of in about 140 cities world. Their presence induces a detour that persists over wide range distances is characterized by nonuniversal exponent. The one-ways pattern then twofold: they mitigate local traffic certain are...

In this paper a bimodal discrete urban road network design problem with bus and car modes is investigated. The problem consists of decision making for lane addition to the existing streets, new street constructions, converting some two-way streets to one-way streets, lane allocation for two-way streets, and the allocation of some street lanes for exclusive bus lanes. Two objectives are consider...
