In this article, the goal was to assess spatial accessibility to the parks in Łódż for example of cycling, individual transport and public transport. Parks represent basic units of recreational greenery in the city. (Czerwieniec, Lewińska 2000). In Łódź are 43 parks, which are located mainly in the rail peripheral or right behind her (Jakóbczyk-Gryszkiewicz 2008). To determine the spatial accessibility to the parks in the analyzed city, were calculated the number and percentage of the population, which living in 2016 in isochrones: 0-5; 5-10; 10-15; 15-20; 20-25; 25-30 minutes from the parks. In the study were taken into account the different means of transport - car, bicycle and public. It was found that the most beneficial for the residents of the city is by bike. In the case of 3/4 of the population of Łódż travel time by bike to the park is less than 5 minutes. Bicycle and public transport provide access to the parks, the vast majority of inhabitants of the city in time to 5 minutes, while individual transport in time 5-10 minutes. Most preferably, due to the accessibility for the residents of the city, are located parks in the city center, and behind its borders, in turn, within the rail perimeter. Over there the population density is greatest, unfortunately, a small area of parks.

The accessibility of urban fire services is a critical indicator in evaluating fire services and optimizing fire resource allocation. However, previous studies have mainly concentrated on measuring the spatial accessibility of fire services, and little, if any, consideration has been paid to exploring the spatiotemporal dynamics of the accessibility of urban fire services. Therefore, we used real-time travel time to extend an existing spatial accessibility method to measure the spatiotemporal accessibility of fire services in a case study of Nanjing, China. The results show that (1) the overall accessibility of fire incidents and fire stations in Nanjing, China, is uneven, with relatively high accessibility in the southwest and northeast of the city center; (2) the number of fire incidents with low-level accessibility apparently increases in rush hours (i.e., 07:00–09:00 and 17:00–19:00 hours) in the southeast and north of the city center, and the fire incidents with medium-level and high-level accessibility easily change to lower levels under the influence of traffic congestion, with fire incidents with medium-level accessibility being affected the most; (3) the accessibility of fire stations changes over time with an obvious W pattern, with lower accessibility during rush hours than at other times, and several fire stations in the city center present an asymmetric W pattern; (4) the accessibility decline ratio for fire stations in rush hours is greater in the city center than in urban suburbs, and the decline ratios are strongly related to the travel time increase and the percent increase in uncovered fire incidents during rush hours. The results and findings demonstrate that our method can be used to explore the spatiotemporal dynamics of the accessibility of fire services, and so can guide policymakers in improving fire services.

Bus travel time on road section is defined and analyzed with the effect of multiple bus lines. An analytical model is formulated to calculate the total red time a bus encounters when travelling along the arterial. Genetic algorithm is used to optimize the offset scheme of traffic signals to minimize the total red time that all bus lines encounter in two directions of the arterial. The model and algorithm are applied to the major part ofZhongshan NorthStreet in the city of Nanjing. The results show that the methods in this paper can reduce total red time of all the bus lines by 31.9% on the object arterial and thus improve the traffic efficiency of the whole arterial and promote public transport priority.

Batam Island’s role as an industrial development center causes fast-paced growth in many sectors with an uneven inhabitant distribution. With most people inhabit the Batam city.The hinterland area is characterised by islands and housing pattern of community clusters in the form of fishermen’s neighborhood along the coastal region with most of the houses are semi-permanent buildings. Most of people’s activities there are consisted of fishing. With limited infrastructure, the mode of transportation used in between the many islands there is with motor boats (Pancung). This is very much in contrast with the condition down the Batam City, in terms of its socio-economic, housing and other aspects.This research is aimed at figuring out the reason as to why people prefer to have their house located in rural areas and finding out the characteristic pattern of people’s movement around the Batam Island.Samples were taken using the sample random proporsional method. Samples were taken randomly from many districts with a proper ratio of people from weak, middle and upper class economic strata. The data were then analyized with cross classification.Results show that people chose rural areas because that where the industrial locations are so that it is closer for them to go to work, and the housin price or rent there are relatively cheaper too. Whereas people who chose to live in the Batam City do so because they want to improve their livelyhood by opening up alternative businesses other than working within the industry.People’s traveling destination is in and around the rural areas because it is where the industries are located evenly and the rest of them travel to the areas surrounding Batam Island. Such as people of Nongsa, 23% of the travel to the Kabil industrial area, and 12% of them go to the city center (Nagoya). In contrast, people of the Sekupang District, 29% of them travel only in and around Sekupang area. Other than that only 2% of Batam inhabitants travel to the islands surrounding Batam Island. Whereas for the people of Sei Beduk, 29% of them go to Muka Kuning and 14% of them to the city center. And for the people of Lubuk Baja District, 32% of them go to the city center (Nagoya), because it is actually the CBD center.The type of transportation used by people in rural areas are mostly private vehicles because they are thought to be more comfortable and safe, as is the case for Nongsa and Sekupang. Nonetheless, 2% of Sekupang inhabitants use motor boats to travel to the islands surrounding Batam Island. In Nongsa, 36% of the people use motorcycle, public transportation account for 32%, and in Sekupang car owners are around 35%. Contrary, the people of Sei Beduk are mostly using public transportation, 42%, due to the already availabel public road and vehicles and only 34% use cars.As for the distance covered by those people, Nongsa and Sekupang residents are 42% cover around 5-10 Km with a travel time of 20-30 minutes a day. Whereas the people of Sei Beduk, 45% of them only cover 105 km in around 10 minutes a day due to the proximity of their living place with the industrial location.On the other hand, Lubuk Baja (city center) people are 43% using cars,  for the are much more comfortable and allow them to have higher mobility. And only 31% of the inhabitants there use public transportation. Most of the people there cover 1-5 km (52%) to 5-10 km (27%) a day with a travel time of around 10 to 20-30 minutes.

A properly functioning public transport is one of the most important components of urban mobility for the population. Due to spatial inhomogeneity and overall socio-economic differences within a city, there are often considerable disproportions in the quality of transport services within its districts. Also, the city of Krakow is no exception in this case. For a comparison of public transport accessibility in 18 Krakow districts, 7 major quantitative and 5 minor indicators were created. These indicators include the most important characteristics of transport services such as accessibility, frequency, connectivity of connections, and ratios of tram public transport subsystem. The resulting values give a fairly comprehensive picture of the quality of the transport services. Overall higher values for most indicators occur in the central districts of the city. However, due to the complexity of the observed characteristics, it is possible to discover significant differences in the structure of individual indicators. Peripheral districts reach higher amplitudes, which means that in some aspect they have even better transport services than the city center. Yet, at the same time, we also find opposite extremes here, highly below-average values for most other indicators. A detailed analysis of the results provides a unique perspective on the disparities among districts. It can also serve for specific identification of strengths and weaknesses of transport services and its possible optimization.

Accessibility to and from urban centres allows small communities’ dwellers to participate in primary activities and use essential services that are not available on-site, such as educational, work and medical services. Public transport networks are supposed to enhance accessibility and pursue equity principles, overcoming socio-economical differences among people that can exacerbate during crisis. In this paper a methodology is proposed and implemented to assess small communities’ accessibility via public transit. A metric is defined based on the calculation of total travel time, taken as a proxy of travel impedance, with consideration of in-vehicle time, schedule delay and users’ arrival and departure preference curves (i.e. time-of-day functions). A “rooftops” model is specified and implemented under the assumption that travellers cannot accept (scheduled) late arrival or early departure time penalties before and after the participation in their activities in the main urban centre, as many activities rarely admit time-flexibility. Also, a public transport specific impedance factor (PTSIF) is proposed, in order to account for travel impedance determinants, which are a consequence of service scheduling and routing decisions and not due to inherent geographical and infrastructural disadvantages affecting car users too. An application of the methodology for the city of Cesena, Italy, and 90 surrounding small communities is presented. The city is served by train and bus services. Assessment of small communities' accessibility based on both total travel time and PTSIF is presented and discussed. This practice-ready quantitative method can help transport professionals to evaluate impacts on small communities’ accessibility in light of public transport service changes or reduction. Quantitative approach to support strategic decisions is needed, for example, both to assess public transport strengthening politics against depopulation of rural and marginal mountainous areas and to mitigate the effects of possible increasing concentration of services towards high-demand lines, which may follow as a consequence of budget cuts or contingencies, such as vehicle capacity reductions required by sanitary emergencies.

The park and ride (P&R) parking type is usually located near peripheral public transport stops. These parking places are dedicated to people who, after leaving their vehicle in the parking, continue their journey to the city center using some form of public transport such as bus, metro, rail or tram systems. This article aims to examine the features associated with P&R parking locations in use in Cracow (Poland). The analysis included the number of entries and exits to and from parking during particular periods of the day, week and year, parking time of vehicles, and parking space use. A parking peak hour factor was also calculated, which expresses the crowding degree of vehicle entries/exits in/out parking during a particular period. In addition, the paper presents an analysis of factors determining users to P&R parking use. In the modeling process, logit models were used, which, as stated after analyzing the literature on the subject, were already used in various countries around the world to describe the behavior of P&R parking users. However, so far, such research relating to Polish conditions has been not published in the available literature. The obtained results allowed to state that the most important factors determining the likelihood of using P&R parking in Cracow are age, number of years having a driving license, monthly income (gross), and an average number of trips made during a day. Other variables, which not included in the study, can influence the P&R parking use. However, the presented results are the basis for conducting furtherer, more in-depth analyses based on a larger number of independent variables that may determine the P&R parking use.

Reducing passenger flow through highly frequented bottlenecks in public transportation networks is a well-known urban planning problem. This issue has become even more relevant since the outbreak of the SARS-CoV-2 pandemic and the necessity for minimum distances between passengers. We propose an approach that allows to dynamically navigate passengers around dangerously crowded stations to better distribute the passenger load across an entire urban public transport network. This is achieved through the introduction of new constraints into routing requests, that enable the avoidance of specific nodes in a network. These requests consider walks, bikes, metros, subways, trams and buses as possible modes of transportation. An implementation of the approach is provided in cooperation with the Munich Travel Corporation (MVG) for the city of Munich, to simulate the effects on a real city’s urban traffic flow. Among other factors, the impact on the travel time was simulated given that the two major exchange points in the network were to be avoided. With an increase from 26.5 to 26.8 minutes on the average travel time, the simulation suggests that the time penalty might be worth the safety benefits.

Roundabouts are progressively being utilized on occupied arterial streets for traffic quieting purposes. Be that as it may, on the off chance that one indirect leg is close to a conveyance center point, for instance, stopping territories of strip malls, the passage traffic volumes will be especially high in pinnacle hours. On the basis of the Al-Turkman Roundabout, which is one of the most important roundabouts in Baghdad city, linking the areas of east of Baghdad to the city center in the area of Bab Al-Moatham. This area is characterized by its high traffic volumes (congestion), especially at peak periods causing a low level of service (LOS) with increased travel time delay, costs, and CO2 emissions. The research relied on the use of the SIDRA software to assess these variables by collecting traffic volumes in this area. The research proposed a series of planning procedures which are divided according to serial time scales. These planning procedures are to address the problem of congestion and traffic jams in the area, improve the level of service, and reduce travel time, cost and CO2 emissions. The research concluded that the application of the planning proposals in the study area has improved the level of service from E and F to C, reduced travel time by 16%, reduced costs by 25% and reduced CO2 emissions by 29%.

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.

Parks are an important component of the green infrastructure in cities. They provide multiple benefits for residents’ life. Due to the uneven spatial distribution of parks, it is necessary to evaluate the spatial disparity about residents’ access to parks. The two-step floating catchment area method is suitable for measuring the accessibility of urban parks. However, few studies have noticed the representative of entrances of parks, especially adding them into the process of accessibility measurements. The floating catchment area is often determined by road speed and empirical travel time. In this article, the impact of multi-entrances of the park will be considered and real-time travel time is used in calculating accessibility. In a case of multi-entrance parks in Beijing, the average travel time of the sub-district is calculated, and with the support of the modified method, the spatial accessibilities of car driving, public transport and car-public transport mixed travel modes are obtained. The results show that the time–space compression effect of car driving is more obvious and the mixed travel mode presents the advantage of high accessibility index. This study has a theoretical and practical value for urban planning, such as advising urban planners on the siting of green park space.
