“…Fu [14] developed a model to reveal the relationship between feasible deviations, slack time, zone size, and dwell time. Zhao and Dessouky [15] analyzed the relationship between the service cycle time and the length and width of the service area. Nourbakhsh and Ouyang [16] developed a new structured point deviation system that outperforms fixed-route transit under low-tomoderate demand levels.…”

Flexible transit services, which bring together the characteristics of fixed-route transit and demand-responsive transit, have been proven to be cost-efficient in low-density residential areas. In this paper, a methodology is proposed to assist planners in making better decisions when choosing between route deviation policy and point deviation policy, which are two promising types of flexible transit services. A user cost function is developed to measure the service quality of the transit systems, and analytical models are constructed to compare the system performance under both expected and unexpected demand levels. Based on the experiments for various scenarios over a real-life transit example, the critical demands, which represent the switching point between the two competing service policies, have been derived. Our findings show that point deviation policy is more efficient at low-demand levels, while route deviation policy is a better choice at low-to-moderate demand levels. At unexpectedly high demand levels, route deviation policy is better able to accommodate rejected passengers than point deviation policy.

“…Quadrifoglio, Dessouky, and Palmer (2006) developed an insertion algorithm to schedule a MAST system; in this paper the efficient use of control parameters significantly improved the performance of the algorithm. Zhao and Dessouky (2004) studied the optimal service capacity through a stochastic approach. Malucelli, Nonato, and Pallottino (1999) also approached the problem, including it in a general overview of flexible transportation systems.…”

W e develop bounds on the maximum longitudinal velocity to evaluate the performance and help the design of mobility allowance shuttle transit (MAST) services. MAST is a new concept in transportation that merges the flexibility of demand responsive transit (DRT) systems with the low-cost operability of fixed-route bus systems. A MAST system allows buses to deviate from the fixed path so that customers within the service area may be picked up or dropped off at their desired locations. However, the main purpose of these services should still be to transport customers along a primary direction. The velocity along this direction should remain above a minimum threshold value to maintain the service attractive to customers. We use continuous approximations to compute lower and upper bounds. The resulting narrow gap between them under realistic operating conditions allows us to evaluate the service in terms of velocity and capacity versus demand. The results show that a two-vehicle system, with selected widths of the service area of 0.5 miles and 1 mile, is able to serve, respectively, a demand of at least 10 and 7 customers per longitudinal mile of the service area while maintaining a reasonable forward progression velocity of about 10 miles/hour. The relationships obtained can be helpful in the design of MAST systems to set the main parameters of the service, such as slack time and headway.

“…Therefore, these drivers are free to propose fuzzy requests to their customers. Third, driver performance appraisal is not only related to the number of clients served and vehicle miles driven, but is also influenced by customer reviews in online evaluation systems, thus incentivizing drivers to request customers to adapt their pick-up or drop-off locations or to give them high user ratings for efficiency and remuneration (Zhao and Dessouky 2008).…”

This research proposes a theoretical model to explain customer compliance with employee fuzzy requests in service encounters from a self-determination theory perspective. Utilizing data collected from 382 car-hailing users in south China, the model was examined through partial least squares structural equation modeling. Results revealed that identified and integrated regulations are positively related to customer compliance. Furthermore, identified regulation is positively affected by sense of relatedness, while integrated regulation is positively influenced by perceived autonomy support, self-efficacy, and sense of relatedness. This study provides important implications for scholars and managers by establishing a self-determination mechanism.
