Exploring active transportation investments and associated benefits for municipal budgets: a scoping review

Municipalities play an important role in the planning and development of communities that support active transportation (AT), which refers to human-powered modes of travel, such as walking and cycling. Municipal-level stakeholders involved in land-use and transportation infrastructure planning consider multiple social, environmental and economic considerations to inform decision-making and investments in AT. Evidence around the fiscal benefits of AT investment for local governments has not been systematically identified. This scoping review sought to explore the existing evidence regarding investments in AT and opportunities for savings on municipal expenditures and revenue generation. In total, 7060 records were located and screened; of which 162 full-text articles were reviewed. Ultimately, 23 articles met our inclusion criteria and were included in this review. The available evidence focuses on potential economic benefits of AT in the areas of tax revenues, property values, consumer spending and employment, all of which are relevant sources of revenue generation in municipal operating budgets. An evidence gap was identified regarding AT infrastructure investments and benefits corresponding to municipal expenditures (e.g. maintenance cost savings). Notably, a large portion of literature was published after 2009, suggesting that municipal-level evidence on the fiscal benefits of AT investments may just be emerging.     

水泥稳定砂砾就地冷再生工艺及其节能环保意义

道路损坏后路基和路面材料的再生利用不仅能够节约大量宝贵的筑路材料,而且具有重要的环境保护意义。采用冷再生技术将原有旧路面材料以专用机械作业方式进行就地再生,并将其作为水泥稳定砂砾摊铺在原有道路上并作为新铺道路的基础是实现上述理念的成功尝试。     

市政排水系统厂站网一体化调度应用

随着城市化进程的加速,城市排水系统的运行面临着越来越大的挑战。传统的排水系统管理模式存在调度决策支撑不足、效率较低等问题,无法满足现代排水系统精细化管理的需求。探索排水系统厂站网一体化调度模式,对于提高排水系统实际运行效率和管理水平具有重要意义。对上海市某片区市政排水系统厂站网一体化调度应用进行研究,搭建厂站网一体化调度平台,集成排水设施基础数据、物联感知监测数据以及水雨情气象数据数据库,以污水管网干线模型为计算引擎,实现排水运行日常监管、一体化调度支持实际应用等功能,为排水系统高效平稳运行提供支撑。

Expertise in decision-making for large infrastructure projects: from UK trunk roads to High Speed Rail 2

At the decision-making stage, a large-scale infrastructure project is essentially a broad concept, and this means the expert analyses will differ from each other and become contested over time, leading to the emergence of rival narratives. It is only where there is a limited range of expert analyses that the bases for decision-making will remain relatively clear-cut. Over time the contested nature of expertise can significantly inhibit the construction of effective narratives, either for or against the project, and also make decision-making more complex and problematic. Decision makers may also seek greater clarification through the construction of narratives that rise above these disputed areas of expertise, and the scientific evidence becomes less important. This paper examines the changing nature of contested expertise through a comparative analysis of political decision-making between UK trunk roads policy and the case of High Speed Rail 2, through the framework of epistemic communities.

市政道路标志标线存在的问题及改善措施研究

With the transfer of rural population to cities, the municipal engineering construction is becoming more and more rapid, in which the investment in the urban roads convenient for citizens to travel and transport is increasing year by year. With the increasing frequency of the use of municipal roads, the signings and markings playing the role of warning and indication expose some problems that need to be solved urgently, which seriously affect the function and comfort of municipal roads. Based on a detailed analysis of the existing problems and impacts of the signings and markings of municipal road engineering in China, the targeted improvement measures are proposed to ensure the perfection of the functions of signings and markings and improve the efficiency of vehicle traffic, which escort the safety, convenience and comfort of municipal road engineering.
