  • Publication number: 20190266891
    Abstract: The invention belongs to the research technology field of urban transportation planning and traffic big data, and provides a method to quantitatively analyze the impact of urban built environment on road travel time. Firstly, the average speed and the built environment attribute information of each small road section are extracted, based on the taxi GPS data and the spatial geographic information data on the research route. Then, taking the average speed of each small section as the dependent variable, the built environment attribute of the road section is used as the key independent variable, and the virtual variable of the nearest intersection type of the road section is used as the adjustment variable. The regression analysis is carried out with considering the interaction between the key independent variable and the adjustment variable, and the key independent variables which significantly affect the average speed of the road sections are selected from the obtained regression results.

The optical grating, the electric motor and the optical grating positioner are all mounted on the substrate. The optical grating is circular or rectangular, and adopt transmission or reflection type optical grating. A light beam is incident on the optical grating and generates diffraction, and when the electric motor drives the optical grating to continuously move relative to the incident light beam, diffracted light will generate a frequency shift, thereby realizing the phase modulation of the light beam. The optical grating phase modulator has the advantages of high phase modulation speed, high regulation precision and wide regulation range, thereby improving the whole performance of an interference photoetching system.
