Peak Parking

Park-and-ride (PnR) facilities provided by Australian transport authorities have been an effective way to encourage car drivers to use public transport such as trains and buses. However, as populations grow and vehicle running costs increase, the demand for more parking spaces has escalated. Often, PnR facilities are filled to capacity by early morning and commuters resort to parking illegally in streets surrounding stations. This paper reports on the development of a location-based parking finding service for PnR users. Based on their current location, the system can inform users which is the best station to park their cars during peak period. Two criteria—parking availability and the shortest travel time—were used to evaluate the best station. Fuzzy logic forecast models were used to estimate the uncertainty of parking availability during the peak parking demand period. A prototype using these methods has been developed based on a case study of the Oats Street and Carlisle PnR facilities in Perth, Western Australia. The system has proved to be efficacious and has the potential to be applied to other parking systems.

Prioritizing public transport is one of the most effective measure to increase the attractiveness and competitiveness of public transport in relation to individual vehicles. The main goal of this study was to examine the possibilities for reducing the travel time of tram vehicles by giving priority at signalized intersections in terms of sharing the traffic lane with personal vehicles and under conditions of strong conflict flows with private transport. For this purpose, we used the simulation tool VISSIM and its module EPICS. A methodology for determining weighting factors for prioritizing public transport flows was developed based on conflicting passenger flows in public transport vehicles and passenger cars. Three scenarios were tested in the study area: (1) “do nothing”; (2) unconditional priority; and (3) conditional priority. The results showed that unconditional priority led to unsustainable traffic conditions for personal vehicles and public transport. In contrast, conditional priority reduced the travel time of public transport on certain corridors by between 7.64% and 18.76% in the morning peak period, and 5.60% to 22.50% in the afternoon peak period.

Operating Strategies

Transportation is a live wire for national development regardless of a nation industrial capacity, population or technological development. It gives expressions to policy initiative in areas like health, education, employment, etc., and in the absence of it, these facilities would be inaccessible. Viable operating strategies for public transport between Federal University of Agriculture, Abeokuta (FUNAAB), Ogun State Nigeria Campus and Camp Terminus in Abeokuta were evolved. Traffic study was conducted for seven (7) days to determine traffic volume and peak periods (morning and evening) along the route. Questionnaires were administered to the road users to obtain factors (availability of vehicles, travel time from Camp Terminus to FUNAAB, road condition, operational cost, comfortability of the vehicle) needed to generate operating strategies. These factors were subjected to statistical analysis. The traffic volume revealed that Private cab had the highest traffic flow for a.m. peak period (8: 00 – 9: 00 am) from Mondays to Thursdays while Public cab had the highest on Fridays to Sundays, and at the pm peak period (4:00 – 5:00 pm), Public cabs had the highest traffic volume on Wednesdays, Saturdays and Sundays while the Private cabs had the highest on the rest days of the week. The analysis of the sampled population showed that public cab had the least total time travel (36.1 minutes) followed by mini- bus (37.8 minutes) while the school bus had the highest (43.7 minutes) and this justified the reason why 40% of the population choose to travel by public cab, 33% by mini– bus  and 27% by the school bus. However, for the viability of the operating strategies, more public cab and min-buses should be provided to ply the road because of their lesser travel time, also provision of more school buses because of the large number of passengers they carry per trip should be provided.

This paper studies how the price affects the demand for public transport in the peak- and off-peak period in the public transport in Stockholm. Further, the study investigates how differences in price elasticities of demand in the peak- and off-peak period can enable an increase in revenues as well as the total number of passengers while dampening the peak-load problem through price discrimination. The data is set up to examine the effect of the price on the number of passengers travelling by subway from January 1999 to December 2008. A number of control variables are used to isolate the effect of a price change in our econometric model. Thereafter, the elasticities of demand for each period are calculated in order to find Ramsey prices that can be used when a monopoly firm maximizes profit and minimizes the welfare loss. The study concludes that the price elasticities of demand differ between the peak- and the off-peak period and that SL should charge a higher price in the peak-period and a lower price in the off-peak period to both increase their revenue, the total number of passengers, and reduce their problems associated with the peak-load demand.

Causes Of Delays

This research presents studies on a segment of highway to determine the quantitative factors that inuence transit services. Travel time and delay study is one of the method to determine quantitative factors. Tour time is described as the average period of time required to journey from one region to some other. Total departure time consists of gadgets which include total working time, places and general delay time. The examine section was done in Prithvi chowk to Tal chowk of Prithvi Highway which is turned to be 12.5 km long. Additionally, it has been found that the principle variables affecting travel time are: postpone time because of forestall selecting and choosing up passengers, bus model and bus size.32 trips public transport carrier and a 10 trips non-public automobile journey have been held during peak hours. Models are developed the use of SPSS software to become aware of the relationship between the causes of delays and the overall-time delays. Travel time and learning delays can help reduce the number of private vehicles operating and increase the number of public vehicles in order to reduce congestion and improve the e efficiency of the public transport system. It turned into determined that there was a full-size distinction in tour time among the use of the public transit services and the car.

Service Efficiency

In a public transport network, an integration between lines generally involves, on one hand, the reduction in the number of direct links, which forces users to perform more vehicle switches, and on the other hand, the possibility of supplying a greater number of rides with the same mileage. Thus, the conversion of a direct link scheme to a feeder-trunk one to improve transit service efficiency in weak demand areas produces both negative and positive effects on accessibility. This paper deals with the built of a model able to estimate an equivalent travel time, taking into account the discomfort caused to users by the vehicle switch and the benefit arising from the greater availability of public transit rides. To validate this model and highlight benefits and limitations resulting from feeder-trunk supply schemes an application to a case study was developed.
