Reliability-based congestion pricing model under endogenous equilibrated market penetration and compliance rate of ATIS

A reliability-based stochastic system optimum congestion pricing(SSOCP) model with endogenous market penetration and compliance rate in an advanced traveler information systems(ATIS) environment was proposed. All travelers were divided into two classes. The first guided travelers were referred to as the equipped travelers who follow ATIS advice, while the second unguided travelers were referred to as the unequipped travelers and the equipped travelers who do not follow the ATIS advice(also referred to as non-complied travelers). Travelers were assumed to take travel time, congestion pricing, and travel time reliability into account when making travel route choice decisions. In order to arrive at on time, travelers needed to allow for a safety margin to their trip.The market penetration of ATIS was determined by a continuous increasing function of the information benefit, and the ATIS compliance rate of equipped travelers was given as the probability of the actually experienced travel costs of guided travelers less than or equal to those of unguided travelers. The analysis results could enhance our understanding of the effect of travel demand level and travel time reliability confidence level on the ATIS market penetration and compliance rate; and the effect of travel time perception variation of guided and unguided travelers on the mean travel cost savings(MTCS) of the equipped travelers, the ATIS market penetration, compliance rate, and the total network effective travel time(TNETT).

Cancer Pain with Standardized Nursing

Background: The incidence of cancer pain in patients with malignant tumors is relatively high, and pain control is poor, which is closely related to many factors, especially the nursing way. Objective: To explore the effect of standardized nursing model on pain control in patients with malignant tumors. Methods: 50 patients with malignant tumors treated in the Affiliated Hospital of Chengde Medical College from January to December in 2021 were randomly divided into 25 cases in the control group and 25 cases in the observation group. The pain control and medication compliance of the two groups were compared. Results: There was no difference in the corresponding score of admission pain between the two groups (P > 0.05), and the pain score of the observation group was lower than that of the control group (P P Conclusion: Standardized cancer pain nursing can ease the pain of patients, and the medication compliance is better.
