The Smoothing Effect of Carpool Lanes on Freeway Bottlenecks
Real data show that reserving a lane for carpools on congested freeways induces a smoothing effect that is characterized by significantly higher bottleneck discharge flows (capacities) in adjacent lanes. The effect arises because disruptive vehicle lane changing diminishes in the presence of a carpool lane. The effect is reproducible across days and freeway sites: it was observed, without excep...
متن کاملThe Offline Carpool Problem Revisited
The carpool problem is to schedule for every time t ∈ N l tasks taken from the set [n] (n ≥ 2). Each task i has a weight wi(t) ≥ 0, where ∑n i=1 wi(t) = l. We let ci(t) ∈ {0, 1} be 1 iff task i is scheduled at time t, where (carpool condition) wi(t) = 0 ⇒ ci(t) = 0. The carpool problem exists in the literature for l = 1, with a goal to make the schedule fair, by bounding the absolute value of E...
متن کاملCARPOOL: Connectivity Plan Routing Protocol
Basic Internet access is considered a human right, however geographical, technological and socio-economic reasons set barriers to universal Internet access. To address this challenge, we have proposed an access method based on message ferrying that enables free delay-tolerant Internet access to all, and developed Connectivity plAn Routing PrOtOcOL (CARPOOL), a reference routing protocol for the...
متن کاملOptimizing Carpool Scheduling Algorithm through Partition Merging
The rapidly increasing number of vehicles in roads leads to numerous problems in metropolitan areas. Several researchers show that carpooling can be an efficient solution to relieve the pressures caused by large numbers of cars. Previous research on carpools introduces several additional constraints to simplify the problem, but some of them are unreasonable in reality. In this paper, we focus o...
متن کاملReversible and Convertible Lanes
A digital road map is a representation of a physical road network that can be displayed or analyzed by a digital computer. Figure 1 shows a road map and its graph representation. Road intersections are often modeled as vertices and the road segments are connecting adjacent intersections represented as edges in the graph. For example, the intersection of ‘SE 5th Ave’ and ‘SE University Ave’ is m...
