With increasing availability of alternative mobility options for city transportation system, it is necessary to better understand how emerging mobility are impacting the travel demand and consumer-social surplus. However, few study has been conducted to evaluate the social welfare effects of the range of vacant trip in mobility oriented development(MOD) mode. This paper identified the vacant trip and loading rate evaluation model under mobility oriented development mode. recommended solutions to enhance the effective operation of the different mobility services under numerical illustrations, which can offer some beneficial guidance and theoretic basis to the efficiency of MOD in planning and management aspects.

Pricing Schemes

In this paper, we investigate the travel pattern of the day-long commuting in a bisection bottleneck network and the efficiency of pricing schemes with elastic travel demand. We extend the Vickrey model to morning and evening commutes and allow commuters to arrive at workplace late and depart from workplace early. The parking searching time is considered in the morning commute. Next, we derive the independent morning and evening commuting travel patterns without road toll and parking fee. Then, we propose three pricing regimes: duration dependent parking fees; optimal time-varying road tolls; optimal time-varying road tolls with duration dependent parking fees. We compare the efficiency of the four schemes with elastic demand. Theoretical analysis and the numerical examples show that optimal time-varying road toll is the most efficient pricing scheme. Charging a duration dependent fee neither improves nor deteriorates the scheme of time-varying road toll, if the toll rates are appropriately set. The regime of duration dependent parking fee only is less efficient than the regime of independent morning and evening commuting travel patterns without road toll and parking fee. In the regime of duration dependent parking fee, the social surplus decreases with the increase of duration dependent parking fee rate.

Wood industrialization provides a contribution to timber-based building. The Chilean market is based on attributes such as the experience and trust of companies. The sales price, meeting deadlines and quality are attributes that have motivated buyers. There are more attributes to assess that are important for the client and market country: building materials and safety, sustainability, and environmental assessment. Some of these valuations are provided by certifications such as life cycle analysis, reduction of energy, water, gas consumption, thermal, acoustic insulation, fire resistance, etc. The objective is to propose an evaluation tool using sustainability indicators for prefabricated lumber-based buildings, using technical benefits of wood as an option for manufacturing prefabricated structures. They constitute references that can be integrated with international construction standards and with it, a process of improvement of the current standards for the housing solution and protection of the environment. The methodology is based on standards compliance levels, according to current, voluntary, or referential regulations, seeking to differentiate the market offer of prefabricated homes through quality indicators, benchmarking and sustainability. The results are an evaluation model synthesized into three tables according to the category evaluated: materials, products, or structures. It concludes that, to meet demand, the market must adapt its offer to new requirements where it does matter how the housing is produced, not only in the economic aspect, but also its impact on the social aspect and the environment and what it offers in terms of quality of life. The lumber-based building sector needs sustainability attributes indicators to potentiate the companies and start a differentiation business.

New Energy Vehicles

In the competitive market environment, the growth of new energy vehicles (NEVs) faces many obstacles. Demand subsidy or production regulation-related policies are widely used to promote the development of NEVs. A comparative analysis of the effects of the two types of policies on the competitive vehicle market requires further study. To fill this gap, we investigate which type of policy is more preferable from the perspective of the social planner. In this paper, we construct a Stackelberg game with a welfare-maximizing social planner and two profit-maximizing manufacturers producing NEVs and fuel vehicles (FVs), respectively. Interestingly, although both types of policies can increase the quantity of NEVs, demand subsidy also promotes the growth of total vehicles at the same time; in contrast, production regulation reduces the total vehicles. Moreover, compared with the benchmark that no policy intervention, demand subsidy generally improves social welfare, while production regulation improves social welfare only with high consumer preference for NEVs. Nevertheless, production regulation always has a positive impact on the environment, whereas demand subsidy may have a positive impact only when the NEV is very environment friendly. The numerical results show that consumer environmental preferences and the regulation of environmental impact determine which type of policy dominates the other.
