Method for evaluating real-time operation levels of wide-range urban public transport line networks on basis of GPS (global positioning system) data of buses

The invention discloses a method for evaluation real-time operation levels of wide-range urban public transport line networks on the basis of GPS (global positioning system) data of buses. The method includes preprocessing data; matching maps with one another; computing travel time indexes; computing station stopping time indexes; computing congestion indexes. Erroneous, repeated, missing and redundant data of the real-time GPS data are processed at the step for preprocessing the data; spatial-time locations of each single GPS point on the corresponding map are estimated at the step for matching the maps with one another; the travel time indexes are travel time indexes of each single bus on a single secondary road section on the basis of map matching data of the single bus, so that travel time indexes of whole road networks can be obtained; single stopping time of each single bus at each single station is computed according to the duration from the moment when the bus is positioned at the station to the moment when the bus leaves the station, and accordingly the station stopping time indexes of the stations can be solved; the travel time indexes and the station stopping time indexes are combined with one another and are analyzed and processed at the step for computing the congestion indexes, and an index which can represent the degree of crowdedness of the road sections by the aid of bus travel time and bus station stopping time can be ultimately solved.

The invention discloses a system and a method for utilizing a portable intelligent terminal to assist in automatic navigation. The system comprises a navigation apparatus and a portable intelligent terminal that is connected to the navigation apparatus by a network. The method comprises the following steps that: the portable intelligent terminal obtains position information by a satellite positioning module and sends the position information to the navigation apparatus; and the navigation apparatus uses the received position information and a current position of the navigation apparatus to carry out navigation route planning and carry out navigation; meanwhile, the current position information of the navigation apparatus and the planned route are sent to the portable intelligent terminal as well as the navigation apparatus and the portable intelligent terminal mutually send respective current position signals in real time. According to the invention, searching for location is simplified and intelligentized; the speed and the accuracy for personnel searching are improved; and the hidden trouble in road security and traffic violation is eliminated. Moreover, the navigation apparatus and the portable intelligent terminal carry out mutual feedback on respective real-time positions, so that the navigation apparatus and the portable intelligent terminal can obtain a navigation route in real time and obtain each other's real-time position information.

Identification of white leghorns red plumage mutagenic mutant genotype and cultivation method for supporting system of red plumage pink shell layer chickens

The present invention discloses a method for breeding the commercial strains of red feather pink-shell laying hens. It provides a primer pair for identifying the red feather causative mutation homozygous genotype of white leghorn chickens, which is composed of the single-stranded DNA molecule shown in Sequence 2 of the Sequence List and the single-stranded DNA molecule shown in Sequence 3 of the list. After the primer was designed according to the upstream and downstream nucleotide sequences of the 18,288,303rd deoxynucleotide in the positive-sense strand of the 11th chromosome as shown in the sequence information of the chicken reference genome Gallus_gallus-4.0 version published in NCBI, the genotype (SNP) at this site is tested through the restriction fragment length polymorphism, the genotype of the site (SNP) was tested through the restriction fragment length polymorphism; the offspring hens obtained by cross breeding the homogenous female parent (the homogenous female parent was obtained through expanded propagation of the white leghorn chickens with the red feather causative mutation homozygous genotype) and the Rhode Island Red rooster as a male parent are all of red feather phenotype, meeting the market demands and enjoying a broad prospect for promotion.
