“…Since they feature so heavily in everyday urban traffic, buses are also the target of frequent complaints concerning erratic waiting and travel times. Studies exist of school buses [14], the effect of bus stops on city traffic [15,16], bus-flow optimization and vehicle location techniques [17][18][19], priority lane usage [20][21][22][23][24][25], and bus priority methods for traffic light control [26]. Moreover the notoriety of buses for arriving in threes, otherwise known as bus bunching or platooning [27], has been explained in terms of a snowball collective effect whereby a particular bus suffers a momentary delay for some external reason, introducing a bottleneck behind which other buses bunch.…”

In the hope of making passenger travel times shorter and more reliable, many cities are introducing dedicated bus lanes (e.g., Bogota, London, Miami). Here we show that chaotic travel times are actually a natural consequence of individual bus function, and hence of public transport systems more generally, i.e., chaotic dynamics emerge even when the route is empty and straight, stops and lights are equidistant and regular, and loading times are negligible. More generally, our findings provide a novel example of chaotic dynamics emerging from a single object following Newton's laws of motion in a regularized one-dimensional system.

“…As early as 1939, the first bus lane system in the world was constructed in Chicago [2]. Since then, due to their superiority in terms of the corresponding transportation capacity, construction cost, and construction period length, such systems have attracted widespread attention and research worldwide and have become widely accepted as a means of alleviating urban traffic congestion [3,4]. Under the guidance of bus prioritization, increasing numbers of cities have planned bus lanes [5,6].…”

Since bus prioritization policies can help mitigate urban traffic jams, the planning of bus lanes has drawn considerable attention. Existing methods suffer from a common limitation, which is that the limited spatial adaptability resulting from certain road condition information cannot be directly specified. Many bus GPS trajectories have been accumulated and can be contiguously gathered if needed. This paper proposes a trajectory-based bus lane planning method. First, we formulize the bus lane planning problem as a multiobjective optimization problem in which the road conditions, traffic flow, connectivity of bus lanes, and construction cost are organized as four constraints, and road utilization and bus punctuality are modeled as two objectives. Then, an evolutionary algorithm-based method is presented to solve the problem. We tested the model in the Nanshan District, Shenzhen City, China. Through a comparison with existing survey-based methods, the parameters associated with road conditions in this method are directly extracted from GPS trajectories, and this method is more effectively deployed than other methods. Since GPS trajectories can cover a wide area if needed, and because the proposed method can be effectively executed, this method can be adapted to large urban scales.

We propose a model of a bus traveling through a sequence of traffic lights, which is required to stop between the traffic signals to pick up passengers. A two dimensional model, of velocity and traveled time at each traffic light, is constructed, which shows non-trivial and chaotic behaviors for realistic city traffic parameters. We restrict the parameter values where these non-trivial and chaotic behaviors occur, by following analytically and numerically the fixed points and period 2 orbits. We define conditions where chaos may arise by determining regions in parameter space where the maximum Lyapunov exponent is positive. Chaos seems to occur as long as the ratio of the braking and accelerating capacities are greater than about ∼3.
