城市交通问题是本世纪以来发达及发展中国家一直为之困扰的问题,尤其是大城市,交通拥堵造成的时间浪费,运营成本的上升,交通事故的增多和噪音、空气的污染等问题则更为严重。如果不能得到有效解决和根本治理,则威胁到我国经济持续、快速、健康的发展。将从我国的交通拥堵现状出发,分析造成城市交通拥堵问题的原因,以期找出解决城市交通拥堵的方法途径。 相似文献

随着我国社会经济的不断发展,我国城市的规模也在不断扩大,随着而来的就是城市人口迅速增长和城市车辆数量的快速增加。在这样的背景下,给城市的交通运输行业带来了极大的压力,尤其是在上海、北京、广州这样的特大城市之中,人民群众对于拥有一个方便快捷的城市交通运输环境的渴求更加突出。针对这样的情况,就需要分析产生城市交通拥堵问题的原因,并通过对原因的分析,从源头上对城市交通问题进行疏导,寻找出具有针对性的解决手段。 相似文献

Pareto-improving and revenue-neutral congestion pricing schemes in two-mode traffic networks 总被引:2,自引:1,他引:1
This paper studies a Pareto-improving and revenue-neutral congestion pricing scheme on a simple two-mode (highway and transit)
network: this scheme aims at simultaneously improving system performance, making every individual user better off, and having
zero total revenue. Different Pareto-improving situations are explored when a two-mode transportation system serves for travel
groups with different value-of-time (VOT) distributions. Since the congestion pricing scheme suggested here charges transit
users negative tolls and automobile users positive tolls, it can be considered as a proper way to implement congestion pricing
and transit subsidy in one step, while offsetting the inequity for the poor. For a general VOT distribution of commuters,
the condition of Pareto-improving is established, and the impact of the VOT distribution on solving the inequity issue is
explored. For a uniform VOT distribution, we show that a Pareto-improving and revenue-neutral pricing scheme always exists
for any target modal split pattern that reduces the total system travel time. 相似文献

Evolutionary game-theoretic model for dynamic congestion pricing in multi-class traffic networks 总被引:1,自引:1,他引:0
This paper describes an evolutionary game-theoretic learning model for dynamic congestion pricing in urban road networks,
taking into account route choice stochasticity and reliability considerations, and the heterogeneity of users, in terms of
their value of travel time and real-time information acquisition. The learning model represents the dynamic adjustments of
users to travel cost changes which may take place in the day-to-day as well as the within-day timescales. The implementation
into a simplified and a real urban road network signifies the important implications of modeling the dynamic and stochastic
learning components of users’ behavior for accommodating the efficient deployment of congestion pricing schemes. 相似文献

AbstractOver the past four decades considerable efforts have been taken to mitigate the growing burden of road injury. With increasing urbanisation along with global mobility that demands not only safe but equitable, efficient and clean (reduced carbon footprint) transport, the responses to dealing with the burgeoning road traffic injury in low- and middle-income countries has become increasingly complex. In this paper, we apply unique methods to identify important strategies that could be implemented to reduce road traffic injury in the Asia-Pacific region; a region comprising large middle-income countries (China and India) that are currently in the throes of rapid motorisation. Using a convolutional neural network approach, we clustered countries containing a total of 1632 cities from around the world into groups based on urban characteristics related to road and public transport infrastructure. We then analysed 20 countries (containing 689 cities) from the Asia-Pacific region and assessed the global burden of disease attributed to road traffic injury and these various urban characteristics. This study demonstrates the utility of employing image recognition methods to discover new insights that afford urban and transport planning opportunities to mitigate road traffic injury at a regional and global scale. 相似文献
