Abstract
Hospitals are essential components of a city; huge traffic demand is generated and attracted, causing contradiction between parking supply and demand. By sharing parking berths, limited space can serve more demand which is beneficial to alleviating parking problems. Aimed at improving the capacity of shared parking, the paper analyzes four parking groups in typical hospitals, which are medical staff, outpatients, emergency patients, and visiting groups. The parking demand of medical staff is rigid. For outpatients and visiting groups, longer walking distance is acceptable and more attention is paid to parking fee. By contrast, emergency patients can accept shorter walking distance and focus more on convenience due to urgency. Under this circumstance, parking behaviors selection models are established by means of Multinomial Logit Model. On this basis, time value is adopted to calculate the tolerance of alterative parking time. Moreover, this paper explores the variation of time window, under different parking impedance. A case study is conducted and suggests that start and end point of a certain time window can be influenced by external factors.
Highlights
As an indispensable part of the city, hospitals generate and attract a huge amount of traffic every day; contradiction between parking supply and demand is serious in most hospitals
Shared Parking [2,3,4] refers to a measure that one parking lot serves the adjacent buildings to meet the needs in all kinds of buildings by means of taking advantage of the differences between demand for time and space among several land uses
It is suggested that variables of parking fee, walking distance, and parking duration are significant since the significance test proved that these factors were the important ones to the decision-making process of outpatients
Summary
As an indispensable part of the city, hospitals generate and attract a huge amount of traffic every day; contradiction between parking supply and demand is serious in most hospitals. The supply of parking berths in hospital parking facilities is relatively constant; facing such ever-changing demand, there will be unbalanced use of the parking resource, manifesting in the fact that parking facilities in daytime are insufficient to meet the demand but at night there are plenty of idle berths [1]. Shared Parking [2,3,4] refers to a measure that one parking lot serves the adjacent buildings to meet the needs in all kinds of buildings by means of taking advantage of the differences between demand for time and space among several land uses. By using Multinomial Logistic Model, the main factors which will influence parking time, like parking purposes, parking prices, and parking fee payers, and so on, are selected and confirmed by Ruan [8]. Guo et al [10] proposed a static game theoretic model to capture the competition among drivers for parking berths
